Editorial
In the world of modern AV we’ve grown to assume that some resources come at little or no cost.
Once system memory was considered so precious that we would spend days doing insane things like writing self-modifying code and hand-coding loops in hexadecimal to avoid any assembler overhead, just to squeeze the whole application into the 8kB that came with the controller. When data screamed across the phone network from one shoe-box sized modem to another at 2400bps nobody redrew an entire screen, just the few bytes that had changed recently. When storage media meant floppy disks that held an astonishing 128kB, nobody kept older versions of documents or embellished their work with cute pictures.
Thankfully those days are far behind us, with bandwidth, storage space and processing cycles now so cheap under most circumstances that they are effectively free. The desktop icons for most contemporary spreadsheets are orders of magnitude larger than the entire 27kB executable file for the original VisiCalc program, which still runs (very, very fast) on today’s Intel/AMD CPUs and is still quite a serviceable spreadsheet.
It’s common to hear IT people use the expressions “bandwidth is free” and “MIPs are free” (Millions of Instructions Per Second
– a measure of the processing speed of a main processor/CPU), this is hardly a statement of fact but more a reflection of our attitude that their cost is an insignificant part of the way we now operate.
The relative abundance of bandwidth, processor power and storage space have led to a scourge on our industry (and most others), the multi-megabyte email. I just adore sitting in a café with only one bar of signal 3G strength waiting while uncompressed TIFF files of the company logo, a background texture pattern and a signature in a highly-decorative font are downloading, only to find the email also includes copies of every email we’ve ever exchanged, a list of all of the company’s branch offices throughout the world (including links to maps and lists of trading hours), the completely-unenforceable 200-word company disclaimer, and finally, the 40-character URL of the data file I actually needed.
Okay, I kinda understand the idea behind a bit of corporate branding or even product promotion as part of communication with clients, but there seems to be no control over how much network bandwidth, disk archive space and mail system processing time this harmless little pursuit is now consuming. The peak of this insanity though is the use of
multi-megabyte decorations and signatures on internal emails between adjacent desks to say that a client called while they away from their desk and would they call them back please. A few days ago I noticed that after a clean-out earlier in the week, I had 87 new copies of each of the two graphic images attached to our company emails. These ones aren’t too big because our graphic design department had optimised the file sizes, but some of these were attached to one word internal emails.
In an industry that’s substantially more ‘bandwidth aware’ than most, we have no excuse for doing things like sending out 1.7MB uncompressed TIFF files of our company logo accompanying media announcements that we’re a clever technology company who sends data reliably across very low bandwidth channels.

If you would like a copy of VisiCalc to play with as a journey down memory lane, just drop Andy a line and he’ll send it to you as an email attachment. No doubt it’ll be smaller than the corporate signature block on your email.

Those of you who know me and have worked with me will know that I’m just a tiny wee bit of a sceptic: always ready to question the real value of a product, idea, work practice, sales claim, design or the numbers on a spec sheet (see it isn’t just you – I’m like that with everybody). You can imagine the depth of that scepticism when, out of the blue, InfoComm offered AV’s readers free access to a website named InfoComm iQ that listed all the audiovisual products available from a vast number of international manufacturers. What’s more they had the temerity to tell us that the database behind the website was constantly being updated, with hundreds of new products added every month.
Having unsuccessfully attempted to create a much smaller version of this concept for ALIA, the lighting association, I knew that such a claim was preposterous. Building the database was the easy part, especially if you have a passion for highly-normalised data structures. The impossible part is getting the data from the manufacturers, doubly so if the data has to be in some standard format like the English language or if quantities like weight or length have to be numbers. And even if you could get all that data once (we never got that far on the ALIA project), the idea of getting regular updates from manufacturers is just a fantasy.
Visitors to the AV website during the last four years may have stumbled across a section labelled ‘Product News’ which is our feed of the amazing InfoComm iQ project. It’s a damned good idea and immensely useful – until you need to find out where to get a product, and discover that the database only covers resellers and distributors in North America.
A couple of years ago, when we discussed this fairly substantial drawback with John Fuchs, InfoComm’s Senior Vice President responsible for iQ, he went away and thought about it and after talking with the programming team for a while, came back
with a significant suggestion: AV-iQ, a version of the system focussed on the Australian and NZ readers of AV. In fact, they liked the idea so much back at the InfoComm iQ secret headquarters (located under an extinct volcano – it’s where they plan World Domination), that they’re now building a swag of regionally-focussed versions of iQ that provide information on the locally-available products and the local resellers.
InfoComm and Alchemedia (the company that publishes this magazine) have been out on the road talking to local importers, manufacturers, distributors and resellers, getting them to become a part of AV-iQ and thus provide the data to add to the existing international and North American material to give us a truly local version of the information and it’s this set of really useful research tools that’s about to be launched at Integrate 2012.
The mystery remains as to how the iQ team was able to develop and populate such a huge database system and how they manage to keep getting the momentum running on product updates and additions. The story goes back about 40 years to an AV integrator named John Fuchs, who needed a better printed catalogue for his business. Here’s the story in his words:
HUMBLE BEGINNINGS
John Fuchs: “When I started my integration company in 1972 I felt a need to have a product catalogue that represented the products my company was bringing to the marketplace, as did many other manufacturers and integrator dealers.
“It was common for a dealer/integrator to have exclusive representation of some lines, so there was high value in investing in marketing those products into your marketplace. Manufacturers each had their own product catalogue but to go into a broadcaster or major corporate account and hand them a bundle of 40 product catalogues from that many manufacturers wasn’t well received.
“Many of us invested in producing an annual product catalogue of a couple of hundred pages and we would talk about projects that we’d done, and effectively it was a marketing tool we handed out. But the cost kept going up and up and it wasn’t uncommon to spend as much as 50 dollars per catalogue.
“However, there was a company called Daniel’s Publishing which saw the opportunity to consolidate the effort. It went out and built relationships with the manufacturers and was capturing product data on a frequent basis and updating its files. It became the default solution if you wanted print catalogues.
“In 1986, together with one other person, I started Professional Systems Network Inc. (PSNI), an organisation of geographically-dispersed integrators throughout the U.S. that enabled us to take care of national accounts that required local installation and support, and I happened to have several of those kinds of customers. It worked out really well and continues successfully today.
“It was also an opportunity to consolidate the production and development of the catalogues that all members of PSNI participated in. So we went from each ordering 500 to 2000 catalogues from Daniel’s Publishing, to representing 20 dealers and buying 50,000 to 60,000 of them. And while all of the catalogues had the same product content, we built them so that you could have 16 pages of custom content in the front of the book and of course the covers could be custom as well. It worked very well and we saved a lot of money.
“A couple of years later I was elected to the InfoComm board of directors, and because of my experience with the PSNI group and working with Daniel’s Publishing, I was assigned the task of negotiating the printing of InfoComm’s own industry catalogue at Daniel’s Printing, and at that point I represented about 80% of their business, so I became pretty involved in how they did it.

INTELLIGENT iQ
“Then in the late ’90s along comes the web, and I just felt the world of the printed catalogue was limited. I looked at the web and thought we’re going to be able to make a difference. And about the same time I was fortunate enough to have a buyer come along for my integration company, so my partner and I sold it, and with the money, among other things we bought Daniel’s Publishing. We converted them from a Quark print-based organisation to an electronic, HTML-based environment and hired people who built the software that we know today as the IQ catalogue environment.
“But before we completed the development work, the 2001 dot com crash came and there we were, with a wonderful concept, a nearly-completed functional, but not-totally-completed business model, and frankly millions of dollars invested, but no access to the necessary funds to finish it. As I had retired from the InfoComm board in at the end of 2000, I simply went back to the board members and showed them what we had and what the potential was, and we were able to negotiate a small deal, nowhere near the recovery of the investment, but we were able to negotiate the sale of the operations of the company to InfoComm. They were nice enough to employ me to continue to operate it, and after a year and a half or so it became my business unit to operate, and that’s the way it’s gone for the last 10 years.
“We created a central resource where all of the products from everybody could be seen and evaluated. At the product level or the vendor level you could then find where the local provider for that opportunity or product or service is located. So it’s a high level of connection capability to funnel new opportunity and new partners.”

GETTING TO KNOW AV-IQ
AV-iQ can make a huge difference to the way you work. Even before AV-iQ goes live in time for Integrate, its forebear, InfoComm IQ, has for years been an immensely powerful and constantly-updated online tool for locating categorised information about an ever-growing range of audiovisual products available in North America. Simply because the IQ database is so big and so widely used, it has acquired sufficient momentum that no company dealing in that region is prepared to be left behind in maintaining its product information or announcing new products as they enter the market. IQ provides not just a comprehensive list of available products, but monthly listings of every new product added to the database.
IT’S A LOCAL THING
AV-iQ builds on this and takes it several steps further by providing an Australian and New Zealand perspective on this huge pool of data. Not only does AV-iQ limit the data available to those products actually suitable for local conditions and available from local distributors and resellers, it also provides you with information on who and where those resellers are and how to contact them. If you really do need to look at products available for other regions, it’s a simple matter to switch on listings for the Americas, Europe, the Middle East and Africa or Asia.
That local data is not yet complete. Obtaining the local information is a big task that will progress as local companies realise the value of AV-iQ and either take up their free listing or go for the paid listing that provides AV-iQ users with more comprehensive details. If you think your business or products should be listed, please get in touch with the AV-iQ team.
If you find that information from your usual suppliers isn’t listed yet, then you can give them a prod to get on with providing the info to AV-iQ so that it’s all available to you from the one place. If they import products, there’s every chance that all the necessary data is already in the IQ database and simply needs tagging as being available here in Oceania (which in the case of AV-iQ means Australia, New Zealand, Papua New Guinea and some of the Pacific islands).
COMPARING YOUR EQUIPMENT
Aside from the capacity to find data on a huge amount of audiovisual equipment AV-iQ allows you to perform side-by-side comparisons of up to four products from anywhere in the database, suddenly simplifying the problem of selecting the most appropriate product for the task. This is the killer-capability of AV-iQ.
The product comparison tool is about to vastly increase in power with the introduction of a new and significantly more powerful method for storing specifications. As the only suitable standard available, the IQ team have adopted the standardised equipment data format specified for Building Information Modelling (BIM). Capable of holding very detailed and complex data about all manner of devices, the BIM-format product information will empower the AV-iQ comparison tool to provide much more accurate apples-with-apples comparisons, allowing you to use the tool as a sharp and accurate scalpel, rather than a chainsaw.
BIM format data will also greatly enhance AV-iQ’s search capability, allowing the use of data filters to limit searches within a category to products with specific properties such as focal length, weight, or power consumption. As the existing data format for specs is at best haphazard, the addition of the refined search involves a major rewrite of the search engine and is currently under development and slated for release this year.
GETTING YOUR OWN IQ
By registering for My iQ (it’s free) you can save the results of your searches and data comparisons and design your own email news services that will keep you informed about product updates in particular categories or from specific manufacturers or news on topics that interest you.
The AV-iQ toolset can facilitate a surprisingly wide range of AV tasks whether it’s designing a system, preparing a quote, finding a supplier, documenting a job, keeping up to date on the gear you’ve got or making decisions about the gear you want to own. The hype on the front cover of this magazine may actually be true: AV-iQ probably can change everything about the way we work. – Andy Ciddor

Despite the stagnation in the US economy and the decision by former mega-exhibitor Extron Electronics not to exhibit this year, InfoComm 2012 in Las Vegas was about the same size as the 2011 show. At 34,268 show visitors, attendance was up by 4% from 2011, while enrolments in the wide variety of InfoComm University courses were up by an impressive 15.6% to 6940.
An imposing 933 stands covered over 4.5 hectare (487,000sqft) of floor space across two of the Las Vegas Convention Center halls, each slightly larger than the playing field of the MCG. Although I was only able to stop in and visit about 5% of those stands during the three days of the show, I did spend the first two hours of the show doing a brisk, non-stop walk down every aisle, trying to get a feel for the lay of the land.
Perhaps because of the world economic slowdown and some resulting diversion of funds from blue-sky research to product development, I wasn’t struck by any entirely new, attention-grabbing technology at this show. Maybe it’s just not a year of big-headline AV technology breakthroughs. However, I was impressed to see some ideas and technologies that made their debut as proof-of-concept prototypes over the last few years, becoming good, solid, useful products.
AS SEEN THROUGH A PRYSM
The standout example would be Prysm, which two years ago made a big, noisy splash demonstrating its Laser Phosphor Display cubes without making it too clear exactly what technology was inside, why it was so cool and clever, or what on earth you could do with them if you could actually buy some. By the 2011 show, Prysm was simply showing LPD cubes for high-resolution in-store displays, without even mentioning the underlying technology. By InfoComm 2012 there were real, well-finished high-end display products that
are now in demonstration centres on most continents, except this one. The decision appears to have been made to market this as a premium, high-resolution product for displaying high-value products. I suspect this means that LPD panels have turned out to be expensive to manufacture.
Prysm’s use of laser-excited phosphors to produce images comes just a couple of years after we abandoned an earlier technology that used beams of electrons (known in previous centuries as cathode rays) to excite phosphors for a similar purpose. And it’s beginning to look like the next few years of developments in materials technologies may herald a new age of phosphors.
WHAT DO YOU USE A PHOSPHOR?
For some years now, semi-conductor manufacturers have been allegedly producing ‘white’ light from blue LEDs by partially coating them with a phosphor that emits yellow light, then trying to kid us that Blue + Yellow = White (yeah, but at a CRI in the very low 80s). The next step down the road to producing better, broader-spectrum light sources is already being taken by light source manufacturers whose customers simply can’t pretend that ‘white’ LEDs will do the job. At InfoComm we saw the HS luminaires for film, video and photographic applications that have appeared from PRG in the last few months. These use LEDs to excite custom blends of Intematix phosphors to produce reasonably-believable colour rendering (CRI of 95). Of course Kino Flo has been using UV-excited phosphors in its fluorescent tubes (but not its LED fixtures) to do this for the last decade and a half. Watch this space (and our soon to be published stable mate – Light+Design) for more about of the New Phosphor Age.
A WARPED (& BLENDED) PERSPECTIVE
A couple of InfoComm shows ago there were demonstrations of two or three variants on the process of camera-based computer vision systems capable of automated blending and warping of multiple projector images. By the 2012 show there were real, working point-and-shoot versions of the technology available, both as value-added features built into image processing boxes (such as Calibre’s HQView530) or as stand-alone specialist products like Scalable Display Manager from Scalable Display Technologies.
The most impressive example of this technology I saw at InfoComm was a 32-megapixel image displayed on a 3.5m wide rear-projection display on the Projectiondesign stand. The image was built from a matrix of 16 of Projectiondesign’s F22 projectors, each accompanied by a WB1920 multi-image processor and linked to a Scalable Display Manager computer and a single DSLR camera. While the image quality was brilliant and it was a lot of fun to watch the software run through the process of realigning the 16 projectors, the most impressive part was having a peek behind the screen at the shelving system supporting the projectors. That was until I started to have flashback-nightmares about endless arrays of SAV slide projectors clacking their way back to slide No.1 on a reset to top-of-show.
HD-BASE-T PICKING UP PACE
The most dramatic example of rapid product maturation and acceptance at InfoComm has been the sweeping uptake of HDBaseT, and the even more rapid uptake of its younger sibling HDBaseT-lite. Just two years ago, during the run-up to InfoComm2010 Valens Semiconductor, which had developed the HDBaseT technology, signed an agreement with LG Electronics,

Samsung Electronics and Sony Pictures Entertainment to push the technology as an industry standard. What’s impressive about this technology is that it pushes full-bandwidth, uncompressed HD video, audio, control signals (such as EDID and RS232), 100BaseT Ethernet and 100VA of power up a 100m length of Cat5e/6 UTP cable. The Valens transmitter and receiver chipset pack all of those signals into the theoretical 10.2Gbps that can be wrung from four intimately-entwined twisted pairs. Last January, to the immediate interest of the industry, Valens released a lower spec (consumer electronics) version that delivers almost all of the above (minus the Ethernet) on 70m runs of Cat5e/6.
In the two years since its release, virtually the entire consumer electronics and AV industries have realised that this is an effective and low-cost way of doing all kinds of things, from home entertainment systems to digital signage, classroom and meeting room systems, exhibitions and museums. They’re signing on to the HDBaseT alliance in their droves and producing products ranging from matrix switchers to display panels and projectors. There were product announcements, product demos and product prototypes all over InfoComm 2012.
The hordes of AV enthusiast kids from Rave magazine and website, who were running round InfoComm in packs of up to 10 – all dressed in bright green T-shirts and getting very excited – awarded HDBaseT ‘Best New Technology for 2012 at InfoComm’. I suppose they must have walked past the HDBaseT alliance stand for the previous two years in their rush to cover this immense show. Now I’m terrified I missed something really important in the nearly 900 stands I didn’t have time to stop at and study in detail. – Andy Ciddor

Midas has made a move into the compact digital console market and the new Pro1 is quite a departure from Midas’ existing inventory. Even Midas admits the Pro1 breaks new ground for the company. An emphasis has been put on making the Pro1 easy to operate so audio engineers new to Midas won’t feel out of their depth. At the same time there is straightforward compatibility with existing Midas show files and operators working with earlier Midas consoles can load files directly into the Pro1 regardless of which Midas digital console it was created on. The Pro1 has 40 primary input channels including 24 XLR preamps and eight aux returns, all of which feature four-band Midas parametric EQ and insert points. The aux returns can be used as returns for the Pro1’s internal FX processors or as additional microphone channels, if needs be. The feature list goes on, too long for here. What we can tell you is the RRP for the Pro1 will start at $13,750.National Audio Systems 1800 441 440 or [email protected]

This new KVM extender supports HDMI video inputs and outputs and extends USB 2.0 alongside uncompressed HD over a single Cat 5 cable. KVM Australia: 1800 222 898 or www.kvm.com.au
1/ BARCO’S NOT-SO-BRIGHT IDEA
We’re not convinced about this one. Barco has added three heavy-duty and high-definition three-chip DLP projectors to its rental portfolio. The HDF-W22 puts out 22,000 lumens, the HDF-W26 26,000 lumens and the HDQ-2K40 a healthy 40,000 lumens. What’s interesting is that all three projectors will be available with a unique adjustable brightness feature. The ‘light-on-demand’ technology means rental companies can tune the light output of their projector to the specific needs of their customer’s event – rental companies only ever need three projector types to generate any brightness level from 10,000 lumens right up to 40,000 lumens, minimising any rental inventory. Presumably locking out higher outputs will ensure customers don’t get more than they paid for, but with the optional GSM module, the rental company can adjust the light output remotely. Or you could just provide a small, cheaper and less powerful projector and leave the 40K beast in the warehouse where it’s not racking up unnecessary operating hours and it’s still available for the big gigs...Barco: (03) 9646 5833 or [email protected]
6/ NEW CHRISTIE 4K NATIVE PROJECTOR
The new Christie D4K25 targets high-resolution markets including amusement parks, automotive designers, planetariums, and applications where native 4K resolution for precision image detail is critical. It also has the ability to use different lamp powers, extending lamp life and reducing cost of ownership, with the Christie D4K25 equipped with automated image alignment for maximising lamp output and brightness. Three sizes are available offering 10,000, 18,000 and 25,000 lumen. Lamp life for the three are an estimated 1500, 2500 and 3500 hours respectively. It has a motorised lens mount and field-alignable digital micromirror devices to ensure that setup is fast, and maintenance time and costs are reduced. Four 3G HD-SDI inputs come standard, enabling native high quality content to be displayed without any need for optional extras or custom units.VR Solutions: (07) 3844 9514 or www.vrs.com.au

3/ CANVAS STRETCHES ACROSS NETWORK
Jupiter Systems has announced its new Canvas visualisation and collaboration solution that allows users across a network to simultaneously see, share and annotate a video or desktop stream. Rather than an audience being in the same room at the same time to view a single display, Canvas allows users to share video streams and captured desktop streams over an enterprise network and every linked PC desktop becomes a display wall. At the heart of the new system is a sharable collage of visual objects. Users can annotate directly on moving video (instead of first needing to capture a still image of a screen). Canvas enables its users to draw with a mouse, finger or stylus on the video itself. Canvas provides object-level security for all sources. For example, if a canvas of video sources is shared with a remote user, only those sources the remote user has permission to view are displayed. System access requires user authentication using standard user name and password combinations established by the client’s IT department.

5/ MULTITOUCH ADD IR PEN
MultiTouch has announced infrared (IR) pen support for its interactive multi-touch displays. The MultiTaction IR Pen software will enable users to write, draw, sketch, and brainstorm designs and words on MultiTaction Cell displays using most IR pens, and to distinguish clearly between pen and touch interactions. MultiTaction IR Pen software will be bundled as a standard feature in all new MultiTaction displays, and will be offered as a free software upgrade for all current MultiTaction displays. The software enables an unlimited number of pens to draw on a single display or an array of connected displays. Clients can develop collaborative applications that enable more efficient and productive communication. Lightwell: (02) 9319 0311 or www.lightwell.com.au

EXTRON CONTROL: A WORK OF ART
The Art Gallery of NSW attracts over a million visitors annually, many to take in the gallery’s world-class modern art collection. In 2008 John Kaldor, a devoted international benefactor and patron of contemporary art in Australia, donated his $35m collection, resulting in the development of 1500sqm of new gallery space.
And here’s where AV takes interest, given the Kaldor collection relies on audiovisual equipment to either show the art in its best light or actually within the piece itself.
John Harman joined the Art Gallery of NSW in 2008 and was quickly brought up to speed by Laurence Hall, AV Services Manager, with what the new gallery would require. Central to the solution was the design and integration of the control room where the multimedia is based with audio and video that can be extensively patched. John: “Essentially the system we put in has the ability to route audio, video or both pretty much anywhere in the entire gallery.”
The effective management of the space came down to knowing how to control a wide range of audiovisual products, without the traditional time restraints and dependency on programming. During the initial design phase John consulted with Ivan Smith from Data Scene, an innovative, specialist control systems solution provider who suggested Extron’s IPLink range for its flexibility and ease of configuration use. “It’s able to take a range of different display and playback devices and control them,” says Ivan. “For example at one point
we had six different types of plasmas, all different vintages, all part of the artworks, all with different control codes.” With an extensive library of device drivers on the website, Extron is able to affectively cater for the various changes in each new model.
Contemporary artworks are supported by a patched network of audio, video and control signals from an extensive rack area designed by John. Five Extron IPLink control processors reside within the space, simultaneously integrating 24 audio and 24 video channels, completely configured by the Art Gallery. Utilising Extron Global Viewer software the Kaldor Gallery is able to be scheduled for operation and shutdown, monitoring and control of 25 projectors (Ethernet), 25 flat panel displays (RS-232), 14 DVD players (IR and RS-232), and 24 channels of audio. “I like the internal web server,” states Ivan. “It makes support very simple, especially for the Art Gallery as they can put everything online and browse to each device’’.
The Art Gallery of NSW public programs are instrumental to engaging a wide audience, with over 100,000 students a year participating in its popular education programs, most going through the gallery’s Centenary Theatre. With control system gremlins appearing within this environment, upgrading the code-based, proprietary system was going to be very costly. Ivan again came to the rescue with an IPLink-based control system. With the addition of two Extron
TouchLink TLP 700MV, seven-inch colour touchpanels and the IPCP 505 Control Processor, the Art Gallery of NSW has been able to realise full control potential of the Centenary Theatre facilities. Dynalite lighting control, Christie video projection, slide projectors, screen drapes and masking, two DVD players, a set-top box, three computer inputs and six channels of audio via an Allen Heath T-80 mixer are all managed through TouchLink. “The nice thing about Extron Control is the macros are very simple,” says Ivan. “And compared to programmed systems, the result is the same but the complexity in configuring is far less, so it’s faster and easier to troubleshoot”.
The integration of Extron Control products into the new Kaldor Family Gallery and the Centenary Theatre has afforded the Art Gallery of NSW complete configurable control of its facilities. Reconfiguring audio visual Contemporary works and product replacement has become effortless through the use of Extron software and download of drivers. “The flexibility of control made it limitless,” says John. “Its versatility to control is the thing I like most about it”. “You know if these things are successful or not if you see them there 10 years later,” explains Ivan. “I have got a feeling that this is going to be there for a long time”.

When the International Olympic Committee declared “Syd-en-nee” as the successful bidder for the 2000 Games it was to have on-going consequences for our industry beyond what many people even imagined at the time. The Sydney games was an unparalleled success leading to them being declared “the best Olympic Games ever” – probably something the IOC President at the time, Juan Antonio, has rued ever since, because subsequent games’ hosts now wait with bated breath to hear those immortal words said again about their efforts – suck it in fellas, it ain’t ever going to happen. For the record, Juan Antonio wasn’t being so original. Six years earlier the 1994 Lillehammer winter games were declared “the best Olympic Winter Games ever”. Maybe Juan printed out the wrong speech and had to wing his way through the mistake?
NEXT STOP EARLS COURT
The grand spectacle of the Sydney Olympics owed a lot to the technical innovation and prowess of the Australian production companies involved – and it has been a hard act to follow. It’s led to an interesting trend. As the ensuing Olympiads in Athens and Beijing were held, not to mention the Commonwealth Games in New Delhi (has all the gear come back yet?), instead of being an almost exclusive opportunity for local production companies to strut their stuff, the Games’ organisers have still encouraged overseas providers to submit tenders. The reality they recognise is there can be no substitute for knowledge and expertise when it comes to the sheer scale of production we see at events like these now–and Australian companies got that in spades-full in 2000. When you’re staging an Olympic-like event we have seriously
gotten our act together. Despite these accolades, you might think the logistics of sending large, trained crews and a warehouse full of gear halfway across the world would make it uneconomical or, at least, the tenders couldn’t be competitive against the locals in the first place. Again, having the experience is telling when it comes to keeping large productions cost-effective. Shipping containers of equipment over distances becomes a relatively small component of the overall – admittedly large – budget.
So it shouldn’t come as too much of a surprise that several Australian production companies are heavily involved in the London Olympics all thanks, in part, to the legacy of the 2000 Games. One of them is Sydney-based The PA People, which is playing a big role in providing communications throughout all the sports venues for the duration of the competition including the following Paralympics. It should be pointed out that this is completely separate from the opening and closing ceremonies. That’s because the ceremonies are true entertainment productions that have little to do with the sporting side of things – it’s two (or three, really) entirely different production environments. Think about it – Sir Paul McCartney would throw a crap javelin… unless maybe he was aiming for his second wife.
NICK OF TIME
We all witnessed that it was apparently going to be a nail-biting finish to get London and all the sporting venues ready in time – it’s an obligatory news headline leading into every Olympics. It’s fair to say that a lot of requirements for communications were decided later, rather than sooner. Normally, establishing final communication points is pretty much
the last thing done after other technical aspects are satisfied anyway. While the basic design on many venues was clear earlier on with the likes of commentary boxes, scoreboards and OB vans inked-in on the plans, other considerations such as extra cameras locations and audio positions were all subject – as you’d expect – to the whims of media producers and directors arriving and demanding that their two cent’s worth (or should that be tuppence?) be heard and acted upon. The comms for each venue centred around a Clear-Com Eclipse matrix, either a Pico or a Median system. Clear-Com V- Stations were typically provided for the Sports Producer, Announcers, Audio Operator, Vision Mixer and Scoreboard Operator while the Timing, Results and Graphics operators were accommodated using beltpack units.
TONS OF TALKBACK
That’s a lot of talkback cans – and a lot of people trying to get a word in over everyone else.
It’s where Clear-Com’s HelixNet digital partyline had a significant impact on the systems’ designs. The ability to run four discrete channels over a single microphone cable allowed the venues to require less physical cabling – the ever-present spaghetti-like mess of microphone cables – yet still provide dedicated channels to the appropriate comms positions. Even so, with a total of 36 sports arenas to cater for with each one requiring multiple comms outlets for all the operators mentioned above, the numbers mount up. The PA People supplied nearly 400 HelixNet Beltpacks hooked up to 48 master stations. Well over 500 Clear-Com CC-300 one-sided headsets were on hand along with the ubiquitous Beyer DT109 cans and
In The Loop:Olympic CommsThe PA People provided comms for many of the Olympics sporting venues. Here's how they did it.

DT790s. A thousand microphone cables were put in the packer and half as many Cat-5 cables.
Also deployed were 340 Motorola hand-held radios and 130 interfaced radio bases. Many of the comms requirements dealt with operators who couldn’t use a cable connection and a wireless solution had to be provided. Interestingly, the fact that The PA People are based in Australia and the equipment was temporarily imported into the UK for the Olympics created a solution for what might otherwise have been an insurmountable problem. London’s congested radio spectrum wasn’t going to have enough room to allow for the influx of literally thousands of extra transmitting devices. OFCOM is the regulatory body for television and radio communications in the UK and fortunately OFCOM saw the answer right away. Much of the equipment brought in from overseas for the games already used operating frequencies that avoided the issue of the crowding in existing spectrum. It was simply a matter of rubber-stamping these frequencies until the Olympics were over.
PERSONAL BEST?
Among the glamour of the television coverage with its zillion camera angles, the flashing lights, the HD digital scoreboards, the huge PA systems belting out the national anthems (mostly everybody’s except ours) it’s normal to overlook the guys in black tee-shirts sneaking around and making sure everything works. Even more ignored is the talkback and comms systems that keeps everyone in the loop – literally – and how that without it working flawlessly things can go pear-shaped very quickly.
It’s been a quiet, yet mammoth undertaking and while our “overweight, underpowered, over-twittered, social media-addicted” athletes are were a little disappointing, we can certainly put our production companies, including The PA People, up on the winner’s podium. Cue the national anthem – the one about being “girt by sea”, not the sheep-stealing thing.

The number of women’s loos have doubled. It might sound like an irrelevant stat for a magazine such as AV, but it speaks volumes. When Hamer Hall was designed back in the ’70s not much had fun-damentally changed in the design of concert halls for 200+ years. They were big auditoria designed for big symphony orchestras to stretch their legs. But as the women’s loos factoid suggests, the designs were becoming increasingly paternalistic and antiquated.
Since Hamer Hall’s opening in 1982, ‘concert halls’ have become multipurpose and multi-functional. Concert halls need more than an announcer’s tannoy, they need full-blown concert PA systems and a room that can handle high SPL.
Hamer Hall for some years now has been doing its darnedest to move with the times. In fact, prior to it closing down for reno-vations, there were actually more amplified gigs than there were Melbourne Symphony Orchestra concerts. Stand-up comedy, Circus Oz, musical theatre, rock and pop concerts… Hamer Hall was cater-ing to performers and an audience its designers simply couldn’t have foreseen in the ’70s.
The $136m overhaul is clearly significant – financially, aestheti-cally, and practically. What’s more it’s a triumph for the technical team. Led by Head of Production, Frank Ward, the tech team’s initial ‘blue sky’ brainstorming has been rewarded with a world-leading per-forming arts centre.
But first, the acoustics.
THE ACOUSTIC PROBLEM
The Hamer Hall upgrade recog-nised the fact the auditorium it-self needed urgent attention. The sound of the hall was seriously lacking. What could only be de-scribed as an acoustics dream team was engaged. Marshall Day and Kirkegaard Associates tag-teamed on the acoustics, while Schuler Shook undertook the theatre con-sultancy duties.
Identifying the problems wasn’t difficult. The MSO complained they couldn’t hear each other or the room/audience – there was a seri-ous disconnect. This unfortunate acoustic quirk of the room meant the stalls area nearest the stage (for the people in the expensive seats) was less than immersive. In fact, committed MSO patrons would of-ten plumb for the cheap $25 tickets in the dress circle because it provid-ed a better sonic experience.
Superficially, since the refurb, the hall doesn’t look transformed. The differences may appear subtle but they are profound. Acute an-gles in the stage surrounds have been softened. The upper balcony ‘arms’ and walls near the stage have been removed, allowing a more pleasing reverberation to de-velop in the room. The floor area of the stalls has been narrowed by three metres and in so doing has decreased the overhang from the circle above – which has made the room more acoustically ‘intimate’, providing for a greater sense of envelopment. Good envelopment brings patrons psycho-acoustically closer to the orchestra and comes
as a result of hearing diverse sourc-es of reflections – not just the wall next to you.
Lastly, as a couple of acoustic glacé cherries, a flocked paint has been applied to the rear walls to re-duce some of the HF zing for people nearest the boundaries, and deploy-able acoustic drapes are available to dampen down the room further if required.
How’s it sound? As of going to press, Hamer Hall had only been open a week and the MSO hadn’t actually had it’s first public hitout. Saying that, in tests, the MSO and Australian Chamber Orchestra are much, much happier. Mostly, thanks to an amazing innovation – a variable acoustical reflector.
REFLECTOR REFLECTIONS
Any acoustical performance on stage is going to need a reflector overhead of some sort in order to take the sound and bounce it back to the musicians so they can hear themselves playing on stage and also to reflect it out into the audi-ence. Building such a reflector per-manently into the architecture isn’t such a big deal, but when you’ve got a rock band with thousands of watts of foldback going full throt-tle, these reflectors become a total sonic liability.
Previously, Hamer Hall had the traditional ‘80s acoustic dishes sus-pended above the stage but they provided patchy assistance at best — brass wasn’t getting much of the violas but plenty of the violin, by way of (a fictional) example [no-body gets much of the violas – Ed].
Hall You Could Wish For$136m is a lot to throw at a refurb, but Hamer Hall’s technical department isn’t complaining.

FEATURE 033
What’s more, the area above the stage was a mess. The acoustic dishes weren’t as ugly as they could have been thanks to the even-uglier PA rigging and lighting bars con-cealing them from full view.
So the trick for Hamer Hall was to design an elegant system that could be flown in and out, and, what’s more, not interfere with the operation of fly bars and winches. As far as the team was concerned, such a system didn’t currently exist anywhere, so it needed designing from scratch. Bob Shook, principal of US-headquartered theatre con-sultants, Schuler Shook, picks up the story:
“We wanted to ensure the hall had a new degree of technical so-phistication in order to keep to a schedule: the Melbourne Symphony on Wednesday night, Tina Arena on Thursday night and Circus Oz on Friday night. And the people that do that want the minimum of la-
bour and time spent going from one setup to another.
“Schuler Shook introduced the idea of the ‘Technical Zone’ over the stage. It’s an insertion into the auditorium. Its primary purpose is to contain a sophisticated degree of mechanical and automated rigging. It allows stage lighting, stage scen-ery and stage effects to be raised above the stage with a minimum of person-power. And it also supports the new acoustical reflector.”
Ah, yes, the pièce de résistance, the acoustical reflector…
Bob Shook: “The new acoustical reflector is the result of a collabo-ration between the acousticians, Kirkegaard Associates and Mar-shall Day, Ashton Raggatt Mc-Dougall (ARM) as architects and Schuler Shook as theatre consul-tants. An acoustical reflector has to fulfil so many different roles: It has to first and foremost work for the orchestra, and for other different
types of acoustic music performed in Hamer Hall. It also has to look like it belongs in the space. That was ARM’s task. Schuler Shook’s role was to design something that could be there when necessary and not be there when it wasn’t, and to be there in different configurations depending on the type of event.
“The reflector itself weighs about 12 tonnes and can be reset into a number of different configu-rations [i.e. it’s not just either up or down; it can be re-shaped] and minimised when it’s not needed for non-symphonic events – all in less than a minute.”
The design was handed to Jands which engineered the five panels, and according to all sources did so ‘magnificently’. It fulfils quite a for-midable brief: the assembly of each of the five panels tilts on four axes; the panels house the orchestra light-ing; the panels contain penetrations for the microphone reelers and
pin spots to drop through; there are slots for the flybars and some lighting rig to fly under the reflec-tors; each panel is three metres wide but is only 0.8 metres when folded away; one of the panels has a mid-dle section that lifts independently to allow passage for the centre speaker cluster…
Jands built the frames, with giant crank shafts and ASM steel-band hoists doing the articulating. It en-gaged a boat builder to manufac-ture the exterior – a fibreglass resin and aluminium-honeycomb panel which met the acoustic require-ments, with a bronze skin provid-ing the aesthetic. We’ve put a short video of the panels in action on our website. Have a look and I’m sure you’ll agree that these panels are as beautiful as they are ingenious.

BACK OF HOUSE JOY
Hamer Hall was designed to accommodate a resident orchestra. Bumping in and out huge productions wasn’t on the radar 30 years ago. But in more recent years the load-in facilities have proven to be a real bottle neck.Under the direction of Schuler Shook’s Jim Hultquist, the dock has now doubled in size and, thankfully, doesn’t share space with the food and beverage services. The back of house hydraulic scissor lift is now a capacious 8m x 3m, with egress to a spacious room — more than enough real estate for a mass choir or AC/DC’s backline. A healthy 3m-wide door now opens to the staging area – enough to back a car through, or indeed (more likely) huge sleds of equipment onto stage.
Overhead, the flying system has been completely overhauled. The previous setup was a labyrinthine nightmare. And with the new Tech Zone being instituted (with its 70 tonnes of steel, including five tonnes of bolts!) it allowed all the new ASM stage winches to be housed above the choir sides in acoustically treated rooms. A Waagner Biro automation system has been implemented and also controls the two stage lifts which retain their old motors. The new flying system is capable of picking up 16 tonnes of staging equipment and is millimetre accurate. All this work was carried out by Jands.
a new Meyer Sound PA. It replaces the old Meyer MSL4-based system and was selected as a result of a rigorous and fiercely contested shootout. With Meyer’s D-Mitri acting as the digital ma-trix backbone, 12 system inputs feed a whopping 102 outputs. From input stage, there are three Digico stage racks (two on stage and one upstairs for the flown orchestral mics) addressed by the two Digico SD7 consoles via an Optocore fibre-based network loop. The audio travels out of the Digico systems via AES digital into D-Mitri, with D-Mitri going about its business in AVB (Audio Video Bridging protocol) via a dual-redundant Cat-6A network.
Nick Carol, Head of Sound: “We have two DCM [D-Mitri Core Matrix] units. One’s a re-dundant unit. Then from three DCPs [D-Mitri Core Processing units] – one of them is a spare – we run AVB to all the output/input boxes and two AVB streams on different switches to get to the different nodes.”
With 102 outputs you’d think perhaps that every speaker in the house is individually ad-dressable. Erm… not quite.
The main L/R Milo arrays (nine elements per side) are complemented by four Melodie delay
hangs (six per side with a 5600HP flown sub). A low-profile centre cluster of eight Minas takes care of conductor announcements. UPM-1P speak-ers are used for under-balcony fill to refresh the high-end deeper into the room. Two lines of front fill speakers are installed, depending on whether the orchestra pit is being used or not. Additional, high-powered front fill can be brought in to line the front of stage for high-SPL shows.
If seating is occupying the orchestra pit floor space, the main PA hangs can track back, down-stage, by 2.5 metres to ensure those front rows don’t have sound directly overhead.
The system design allows for a ‘clean stage’ configuration – for dance events, AGMs, smaller amplified shows and the like – where two layers of recessed Mina arrays in the stage surrounds take care of infill duties. These arrays sit behind perforated panels and are all-but invisible. For acts that require a greater level of amplifica-tion and have on-stage monitoring, the techni-cal team can bring out ground- stacks on stage – each comprises five Meyer Melodie mid/high units and two 700HP subs.
In its acoustic configuration, doors close over the ‘invisible’ in-fill arrays, ensuring the room

How’s it sound? Unfortunately, I don’t have 100,000 people fol-lowing my tweets and I’m not vice regal, so AV didn’t make it to the opening night. But AV attended the third night of Philip Glass’s Qatsi trilogy (12 musicians, half of which were miked up, the other half were playing synth sources) and was duly impressed. It wasn’t a high-energy show, but the PA provided an effort-lessly sweet response. It was ‘sound reinforcement’ in the true sense of the word – just enough, and delight-ful. Meanwhile, Nick Carol, Head of Sound, can’t wipe the smile off his face.
Nick Carol: “We had ([legend-ary system optimisation engineer)] Bob McCarthy in to align the PA and like us he was amazed by how
even the sound pressure levels are in this room. Front to back he couldn’t remember a more even room.”
LIGHTING
The Hamer Hall lighting depart-ment, led by Adrian Sterritt, also had its fair share of ‘firsts’.
Above the stage, the new acous-tical reflector takes care of work-a-day house lighting for the orches-tra. The reflectors incorporate 55 tungsten source lamps for an even white wash (on State Automation sine wave dimmers). The moving rig now packs 18 x Vari-Lite VLX wash lights, 21 x Robe MMX spots, 28 x ETC D40 Lustr LED fixtures, ETC Source Four Seachangers and ChromaQ cyc floods.
Adrian Sterritt: “We would like to have gone all-LED if possible, but we couldn’t because there is no profile moving head that’s bright enough at this point. So that’s why we went with the MMX which uses an 800W fast fit globe. It also punches above its weight for the 800W, it’s full of built-in features and it is quite fast. Meanwhile, the Seachangers give us a great vari-ety of light – full CMY mixing. It
means that we can turn off the oth-er lights, go fanless, and still have the Seachangers to change colour – which is important for orches-tral nights. It’s a similar situation with the ETC Lustrs – fanless. On orchestral nights we can still go co-lourful without fan noise.”
Upstairs in the control booth the lighting department welcomes a brand new PRG V676 4000-chan-nel lighting desk. For redundancy’s sake an additional Mac runs the V676 software.
Adrian Sterritt: “The V676 is streets ahead. It’s designed to do moving lights, data, and it inter-faces with media servers much better. You can configure it in any way you want, and, with the touchscreens, it’s very easy to jump around quickly.”
A Virtuoso network runs the desk while an ArtNet network talks to the 384 State Automation SCR dimmers. On the end of the ArtNet network are a plethora of PathPort nodes (for turning the ArtNet into DMX).
Adrian Sterritt: “We tried to future-proof the venue by putting in so many network points. We’ve
got a fibre ring around the venue and we also have network points from the fibre to breakout, so we can get network almost anywhere in the building.”
ALL IN THE EXECUTION
In extensive, expensive and compli-cated renovation jobs such as this, rarely does the operator, the engi-neer, or the resident ensemble re-ally get what they want. Everyone goes in with the best intentions but budgets and technical compromises more often than not blunt the scope and execution.
Occasionally we hear about good news stories, and Hamer Hall looks to be one of them. From the outset, Head of Production Frank Ward sat his team down and asked them to forget about budgets for a minute and simply dream – what would their ideal setup look like? ‘Sure, sure…’ you can sense the scepticism that must have been in the room even now. But according to Frank, 36 of the 40 points on the wish list have been realised. And in my book, I give that an ‘A’.
Two Digico SD7s (for front of house and monitors) replaces the old Digico D5. Both consoles share two engines (one for redundancy’s sake). At FOH a neat rack of popular outboard items should keep most visiting engineers happy, including TC Electronic delay, a TC M3000 effects device, along with a Lexicon PCM81 and 91 for reverb. Upstairs a studio will allow performances to be recorded. A Digico SD10B will be the centrepiece, with ADAM monitoring and RME audio interfacing.
COMMS
The Hamer Hall refit includes a new Riedel digital intercom system. This system comprises an Artist 128 matrix, a Performer digital partyline system and an Acrobat digital wireless beltpack system.The Artist matrix provides the brains for the entire communications and BOH backstage paging matrix. Critical areas, such as the stage manager’s desk, the FOH mix position and the lighting control room are all fitted with Artist panels, allowing discrete point-to-point communications alongside the traditional ‘loops’. The power of the matrix also allows stage managers to make BOH backstage pages from anywhere, including their wireless packs, in full digital quality.Dual power supplies and redundant CPU cards means this system-critical infrastructure is as bullet-proof as you can get.The Performer partyline system replaces the traditional wired beltpacks found in most theatres. By using AES digital signalling, they are able to get two channels of full-range audio down a standard single one-pair audio cable with minimal noise floor. This means the overall volume of the beltpacks can be kept down, minimising fatigue on long shows. By utilising the new audio cabling throughout the venue, the technicians now only have one patchfield to manage instead of separate comms and audio patch points.The Acrobat wireless system uses 1.9GHz DECT (cordless telephone) technology to talk to 12 wireless beltpacks to operate in full-duplex from a single base. Six distributed antennae allow technicians to roam freely around the backstage and BOH areas without dropout. Since these beltpacks are connected directly to the matrix via MADI, each beltpack acts like a ‘wireless panel’; giving the users access to discrete calls and advanced functionality. By going to the 1.9GHz digital range, Hamer Hall frees up spectrum to allow for the digital dividend without compromising their widespread 2.4GHz wi-fi networks.The system was designed in collaboration with Riedel Australia, and was installed by the KLM Group.

ADD TO CARTMetcash – Australia’s biggest distributors to independent supermarkets – uses smart AV to ensure the prices are ‘down… down, down, prices are down…’
Text:/ Robert Clark
Remaining competitive as an independent business in the supermarket industry can’t be easy, especially considering it is dominated by a powerful, nationwide duopoly. For Metcash, a distributor for many smaller retailers including Independent Grocers Alliance (IGA), it is a daily battle to out-think and out-manoeuvre the ‘Big Two’. When the company decided that a high-capacity distribution centre was needed in Sydney’s west, it was evident early on that it had to achieve high productivity and efficiency targets to keep its clients’ costs down.
The General Manager of Operations (GMO) at the new Huntingwood facility contacted Simon Alder of Alder Consulting to provide AV solutions for the 80,000sqm building (that’s six football fields), and it was clear from the outset that efficiency was a major concern. Of
the initial brief, Alder says, “although Metcash is a very big distributor and wholesaler, its stores are actually quite small. So it had to do it smarter and more efficiently than everyone else but didn’t quite know what that entailed.” The original tender Alder produced was for traditional AV services such as video-conferencing, but after learning of Crestron’s push into what it calls Integrated Building Technology, he decided to widen the scope of his submission. He did some research and returned to Metcash with the suggestion that it combine the control foundation of an AV system with the latest in energy-saving building management systems (BMS) from Crestron. With a cost-benefit analysis revealing that a fully-integrated system could provide significant savings, Metcash enthusiastically commissioned his services. “The GMO was quite receptive to the idea
of power and energy management,” says Alder. “Metcash is on a 15-year lease, and after two or three years, once it gets its return on investment, there will be significant cost savings. Every dollar it’s able to save on energy means less it will have to spend. It can then pass on those savings to all the independent stores.”
GIVEN THE GREENLIGHT
The technology that caught Alder’s attention was Crestron’s Greenlight system, which sits above traditional BMS services to control all facets of a building’s AV and energy usage in real-time. At the user end of the tech is the Fusion software, which brings multiple systems – such as lighting, air-conditioning and security – under the one umbrella. Alder explains: “Traditionally you might have a light switch and a thermostat and a security log, those sorts of things,
FEATURE040
on the wall, but what Fusion does is allow you to combine them into a simple user interface (UI). All the initial systems still do their own things in the background and we’re not actually modifying what they do; all we’re doing is using their capabilities by calling up the presets, or their functionality, and tying it in with the other systems.”
A key example of this uniform integration is the innovative use of the building’s advanced Mobotix security cameras. It was discovered during installation that they could be linked directly to the BMS and provide accurate movement locations of forklifts and staff. This allowed the Fusion software to adjust the lighting system in real-time, based on activity on the ground. Alder explains they were not planning this approach from the outset: “Initially we were going to control the lighting with a beam catch
– in much the same way as when you walk into a shop through the beam and a chime goes off. But then we’d just be limited to that beam, and when the shelves were getting stacked the beams would get knocked and out of alignment, so we were looking for a solution. Then we saw that the cameras were on every aisle, and could give us a detailed, per square-metre picture for the entire length of the aisle. So that gave us considerably more control and more flexibility, with the added advantage of the cameras being up out of the way.” The camera processing can also track the direction in which workers are travelling, which allows the software to progressively raise and dim the lights as they move.
Another important factor in minimising energy usage for Metcash was managing their array of over 80 forklift charging stations. In a normal setting this could present a significant
and extended draw on power but through the Greenlight system Alder was able to link each station to the head-end control unit, giving the user the ability to restrict charging time to low-demand periods.
POWER SWITCH
Central to such accurate measurement and control of energy usage is the system’s Metering Control Unit (MCU). It has three-phase (plus neutral) voltage inputs connected to the facility’s breaker panel, which allows it to monitor both voltage and current. This information can be provided in real-time or logged power usage data to the Fusion software. With this information, the UI displays energy usage through charts and graphs that illustrate the building’s historical and real-time energy consumption. The MCU also has the ability to monitor consumption
“Key to the success of the system was the simplicity of its UI and the accuracy and accessibility of the
information it could provide.”

by area and/or any of the over 250 devices in the building via individual branch monitors, which link to it through current transformer interfaces. The MCU is also Ethernet-based and communicates to the Fusion UI through an automation control system linked via the LAN.
Key to the success of the system was the simplicity of its UI and the accuracy and accessibility of the information it could provide. Alder believes it compares very favourably with previous systems: “Before, if you had an air-conditioning system, for example, going at full blast for three months, you could see at the end of that period it used 20,000kWh, but it wasn’t necessarily clear what that meant in real terms. In these systems, however, you can see its usage in real time and associate it with a dollar value, and if you want, you can have on the screen ‘at 23° it’s going to cost you, say, $250/hr; jump down to 22° and it’s costing you $220/hr’. This control system will allow you to make all of these complex calculations in real time and give you the relevant information for the user. And even people who aren’t technically oriented can have a look at the data, and say ‘okay, well I don’t need to use this so we can turn it off, and we can save $15,000 a year’.”
COMPETITIVE EDGE
Crestron ultimately presented an award to Simon Alder for his innovative use of its technology, but he believes it was just the right time and the right place for the technology to flourish. “It shows what can be done when you have a client who is really willing to do what they can to get ahead,” he says. “And what happens when you’ve got the support of a company who knows the product is new but is willing to really put in and assist in getting it off the ground. I think the more we start exploring the boundaries, the better the results, not only for our industry but for all the other industries.”
For Metcash, the benefit of a BMS that not only gives it powerful and accurate control over its facility but actively saves it money is that of a competitive edge in its industry. As Alder explains: “I think it shows that if we manage to use a great piece of technology to save hundreds of thousands of dollars for a wholesaler, then maybe down the line, that means the average family is saving a little bit of money when they go to the grocery store. So it’s quite nice to think about it that way.”

When the Melbourne Exhibition Centre’s vast new convention centre was opened in 2009 to create the Melbourne Convention and Exhibition Centre, AV went along to have a look at what all the fuss was about. To save you trying to find who’s borrowed your much-thumbed copy of AV Issue 7, here’s a brief summary of what we found at the time:
DOWN MEMORY LANE
In addition to the aggressively low-energy, low-waste approach taken in the building’s design and construction, we were impressed with the decision to equip all 30 of the meeting and conference spaces at a level that would meet the requirements for better than 80% of hires, without moving much more than a hand-held wireless microphone or moving the control point from its long room (portrait) position to its wide room (landscape) operating position.
We marvelled at how the lower level of the 5553-seat plenary hall could be transformed from flat floor to tiered seating in just 10 minutes at the press of a couple of touchscreen buttons and divided into three independent halls by sound-isolating operable walls at the press of a few more. The question in many people’s minds back then, was whether this impressive system would be needed for fast turnarounds often enough to justify the very substantial investment.
The backend systems that support the MCEC’s 30 meeting rooms really made an impression. The nested-star architecture, with a central control room monitoring three satellite control and
equipment rooms, that in turn each feed a cluster of 10 or so meeting rooms, looked like a workable balance between minimised cable runs, operator proximity to the spaces, and centralised control.
Although we didn’t have room to write much about it at the time, in the banquet room we were shown a very spacious venue, fitted with a great deal of cable infrastructure and lots of rigging points, but not very much in the way of gear to hang from them.
BACK TO THE FUTURE
Fast forward through three very hectic years of operations with growing occupancy rates and high demands on the centre’s facilities, and let’s see what’s happening in the real, working version of the MCEC.
For the first two years of operation (during the warranty period for the building) AV maintenance and repairs were carried out by Rutledge Engineering, which had installed and commissioned the technology for the consortium that built MCEC. Since then, technical support, operations, equipment maintenance and repair have been handled completely in-house by MCEC.
Many of the simpler meetings and presentations are now run entirely by hirers using the installed equipment, secure in the knowledge that all in-use venues are monitored by MCEC support staff in either a local control room or master control, with help just a touchscreen button away. Technical Services Manager, Paul Rumble is proud of the fact that many clients never actually get to push that button, because the
support staff have already spotted the problem and either intervened remotely or despatched a tech to the room.
Found in every single meeting room, the custom-designed MCEC lecterns, equipped with everything from both AMX and computer touchscreens, to a wine-chiller and a local computer with its full-size keyboard secreted in a draw, have been a great success. The only drawback to the system has been that the huge range of options and controls on the AMX touch panel have intimidated, and sometimes bewildered, less tech-savvy presenters. To make tech support simpler and reduce the fear for untrained users, a new top-level system screen contains three big, friendly buttons for ‘Computer’ ‘DVD’ and ‘Help’ (though I didn’t see the words Don’t Panic). All existing functionality remains on the next layer of screens.
The Gala Venue lift system that transforms the lower level of the plenary hall from tiered seating to a flat floor continues to be operated by Brookfield Multiplex, a member of the consortium of bodies that built and own MCEC. By now, there’s no question the seating system enables events to be packed pretty tightly into the plenary hall and its three subdivided alter egos. In fact, the plenary complex is getting enough work that the lighting equipment originally intended to be shared with the banquet hall now permanently lives in the plenary hall area.

added to the fleet as a backup for the plenary halls’ existing FLMHD18 and FLMHD14 projectors. And on the matter of projectors: after three years of hard work, the meeting room fleet of HD projectors is scheduled to be replaced this year, so the hunt is now on to find machines that are green, reliable, bright, well-networked and cost-effective to own.
The banquet room has already had all four of its projectors replaced with Christie Roadster HD10Ks to enable good quality projection at the higher ambient light levels required for many functions, especially those with live stage performances. As an added benefit, larger (6m) projection screens are now available as an upgrade for banquet hall functions.
Large national and international events at MCEC are increasingly requiring high-bandwidth video linkups for media coverage, web streaming and live connections to other venues. To enable uncompressed high-definition video to be produced or displayed in any of the meeting rooms, a venue-wide network of HD-SDI cabling and routing has now been installed alongside the existing fibre network by the house technical and engineering staff. It’s ever-so-slightly ironic that a venue which proudly started from day one with an all-digital HD digital video network has upgraded its capabilities by adding 75Ω coax in its newfound digital role.
While death-by-PowerPoint and simple DVD replay still form the basis for many of the presentations hosted at MCEC, an increasing number are using multiple sources that include media servers, network feeds, blended multi-source images, cameras, computer generated effects and interactive material.
These presentations require more than can be achieved with the basic source-selection and overlay capabilities of the standard lectern and PC-based system found in every room, so MCEC staff are constantly putting together custom systems for each booking. As the time taken to assemble, configure and test every system has to be billed to the client,

MCEC have been looking for a way to offer these facilities at an affordable and competitive price. Enter the Video Desk.
After some months of testing various prototype configurations on presentations across the spectrum, the operations and engineering teams have settled on a design for a standard mobile video presentation system built into a desk that can be wheeled into any space in MCEC to run a multi-source and/or multiscreen presentation. Each desk has three 24-inch monitors, two computers with swish video cards, a Barco Screen Pro II video processor, a vision mixer with digital effects and a PTZ remote controller for the cameras located in every room. Soon there will be a dozen of them rolling around the venue.
A MORE SUMPTUOUS BANQUET ROOM
On my original visit to MCEC I got a strong impression that the 1500-seat Grand Banquet Room which can be divided into two independent spaces was treated in the fitout as a bit of a technical Cinderella. The kitchens were superbly equipped, but it seemed that nobody was sure how much work the conjoined banquet spaces would attract, so only basic infrastructure was installed, to allow for a range of future possibilities.
I also noticed the kind of big slap echo that most people (except someone on the original design team) would expect from a pair of very-large, totally-rectangular boxes with acoustically-reflective walls. This is hardly a major selling point for rooms that will feature background music, live bands, stage performances, and endless slurred speeches at weddings, bar
mitzvahs and awards nights – not to mention the odd conference plenary session.
The first step in the solution was to change the acoustics of the rooms to defeat the standing waves between the highly-reflective parallel walls. The ‘back’ wall of the space was modified in shape from being flat to having a series of vertical angled-panels (like a louvred door on its side) to break up the front-to-back reflections. Meanwhile, the ‘side’ walls and the operable wall that divides the space were treated with panels of an acoustically-diffusing material (it looks like carpet) to substantially reduce the reflections from these surfaces without totally deadening the space. The result is a large venue that no longer sounds like one.
With the rooms less live, it was then possible to use a larger PA to fill the space with the bigger, bolder sound needed by so many clients. The existing Nexo GEO boxes were combined and redeployed as a live performance PA and a brand new Meyer UltraSeries system was bought for the banquet room. The PA is flown from some of the new chain hosts that have been hung on rigging points in high-use locations.
AND ON A LIGHTER NOTE
The new, dedicated banquet room lighting rig is also flown on chain hoists hung from the original constellation of ceiling rigging points. While those hanging points may have proved very useful for the current applications of the space, the extensive DMX lighting control network has not proved to be so valuable. With the sparse distribution of luminaires over such a large space, the traditional DMX daisy-chain
topology is much more cumbersome than a DMX-over-Ethernet star arrangement. DMX distribution is being handled by a network of Pathport Ethernet-to-DMX nodes connected via Pathport’s Ethernet protocol, running over the venue’s widely available IP network.
WI-FI FOR THE MULTITUDES
In this second decade of the 21st century, no conference, meeting, working breakfast, trade function or school excursion can take place without plentiful internet connectivity. Never more so than when you’re hosting a conference for thousands of physicists or a symposium for nuclear magnetic resonance diagnosticians who all want to check their emails and tweet about the quality of their dessert at every opportunity.
MCEC is the first venue in the country to offer blanket-coverage of free 512kbps wi-fi. The system is substantially more sophisticated and more capable than what you get from stringing a few commodity wireless access points around the foyer. During a recent physical science conference where evidence for the existence of the Higgs Boson was revealed via an international video link, the system handled a peak of around 5000 simultaneous wi-fi sessions, although its capacity excedes 15,000.
It’s always interesting to visit a new facility a few years after it has opened and see which of the attempts to predict the needs of the future occupants were successful. It will be even more fun to watch the process soon to take place at Darling Harbour in Sydney as the SCEC is demolished and rebuilt.

This is an excerpt from the course INS201 Installation Online, an interactive course addressing advanced science and technology concepts for the AV installer. The program is designed to be easy and cost effective for self-paced learning. The course outlines installation processes and procedures. In addition, it contains more than 40 downloadable PDFs of step-by-step installation instructions.
SELECTING A RACK
All cables eventually lead to electronic equipment, and much of the equipment is typically located in a rack. An equipment rack is the skeletal framework in which key components are arranged and interconnected.
Rack design is the process of selecting options to meet the needs of a specific installation. Equipment is not just mounted in a rack haphazardly. Special consideration is given to how much heat a piece of equipment emits, the types of signals to/from the equipment, if the equipment has an interface component for a typical user and more. This requires substantial pre-planning and design of all system elements, rather than leaving portions of the system configuration to be ‘thrown together’ once the installers arrive at the site.
For example, when carefully planning the design of equipment racks and how system power needs will be addressed you must consider:• What are the major considerations for equipment rack layout?• Is the necessary electrical cabling installed to the rack?• Are all the pipes, conduit and trays running to the rack?• Do the pipes, conduit and trays have enough room to carry the cables to the rack?• What joinery will be needed to finish the rack?• How is cabling run within the rack?• How are system power requirements best communicated to the rest of the design team?• How will heat created by the AV equipment in the rack be handled?
RACK TYPES
The design subtleties of the rack enclosure are purposeful and, in many cases, standardised.
The following are examples of permanent installation racks.Wall-Mounted Racks attach to any type of wall with the proper hardware. They swing open so the technician can access the equipment from the rear for service. AV designers should understand the structural issues associated with the installation of this type of rack to determine if the wall can hold the weight of the populated rack.
Wall mounted rack empty and in use
Fixed Racks are used for most audiovisual equipment. Most have mounting rails which secure the AV equipment.
Gangable rack and simple freestanding rack
Slide-Out Racks are used where there is only a limited service area. The whole rack is pulled forward for installation or service. This type of rack may also have the ability
to rotate or spin in place for installation, wiring and service. These types of racks are mainly used with existing cabinets or joinery.
HEIGHT & WIDTH
Panel Width varies depending on rack type. The interior width of a rack needs to be wide enough to accommodate different types of equipment. The standard equipment rack for audiovisual equipment has a rack space of 19 inches wide (483mm). Racks for computer and communication equipment have 24-inches (610mm) of rack space.Rack Height varies from over 2.1m to less than 30cm tall. Racks are also classified by their vertical mounting space. This specification is given as the number of Rack Units (RUs) available for equipment mounting. A single rack unit is 1.75 inches (44.45mm). Equipment can also be measured in RUs. An audio mixer might be one (1) RU high, while an amplifier might be two (2) RU high. Some equipment, like large switchers, can be 10 RU or more.
On each of the side mounting rails there are typically two or three punched holes for one rack unit. Caged nuts are inserted in the holes for mounting the equipment. The picture below shows the standard EIA spacing for mounting holes. Notice that they are not evenly spaced.
Equipment manufactured for rack mounting has ‘ears’ – extensions on both sides of the face plate which align with the holes in the mounting rail. Sometimes the ears are ordered separately
and attached to the sides of equipment first. Rack screws through the ear holes secure the equipment in the rack. To prevent delays during the installation process check to be sure that the equipment ordered is suitable for rack installation.
RACK ACCESSORIES
If you think of a rack as an organisation space, they are a lot like a cupboard. Just as you can have space dividers, shelves and drawers in a cupboard, similar accessories are available for racks.
Rack blanks are metal panels mounted in empty spaces between pieces of equipment. They can be flat or flanged. Flat blanks are not as sturdy as flanged ones. Both are more appealing than an open space in a rack. Blanks are available as a solid or with vent holes, and in different finishes and colours. You should choose ones which match the installation needs.
Manufacturers also make rack accessories, including:• Drawers, perhaps for storing microphones, remote controls and cables• Shelves, good for consumer equipment which isn’t rack mountable• Sliding shelves, providing easier access• Media holders, slots and dividers for CDs, DVDs or video cassettes• Lighting, helpful in a dimly lit presentation space• Security doors and locks, for securing the entire rack or just one drawer

TerminationThe Fifteen Minute Rule
By Matt Caton
Most of us have been seduced, at some stage, by the drawing power of the excessive home entertainment centre. You know the power. You possibly first noticed it when you installed it in a client’s boardroom. Maybe you notice it every time you set up a concert. You’ve certainly noticed it when you’ve walked into somebody’s house and spotted the massive ‘infinity inch’ plasma / LCD / LED, often accompanied by a world class ‘drum n bass’ sound system and a full reclining cinema chair. It’s enough to incite levels of jealousy that will see even the most discerning budget-watcher go out and buy their own.
So you’ve now gone and bought your own version of the ‘perfect’ home cinema. You sit down, start watching the movie, and for the first 15 minutes, it’s pure heaven. But then something happens. Something so complex that it far outreaches the capabilities of this writer to accurately describe it. Your senses begin to adapt, it becomes your new ‘norm,’ and suddenly the massive screen and crystal picture quality doesn’t seem that impressive anymore.
This phenomenon is often referred to in scientific circles as the ‘Fifteen Minute Rule.’ (It should be noted that this is in no way true, and the Fifteen Minute Rule is something I just made up along the way, but please indulge me.) No matter what the visual feast being delivered to you is, after about 15 minutes, you become so immersed and so ‘used to’ it, that it becomes irrelevant to you.
AT THE MOVIES
Now think about about this; how many
Hollywood blockbuster films have you seen where the filmmaker attempted to wow you for two hours with nothing but special effects? Usually, these films are created by Michael Bay, and sadly even the occasional one from James Cameron. The introduction sequence blows you away and for the first fifteen minutes, you can’t take your eyes off the stunning effects. It doesn’t really carry the movie all the way through though, does it?
It also goes the other way. If you watch a movie with subtitles, or in black and white, or with a grainy picture (from the DVD your sister brought back from Bali), the first fifteen minutes are somewhat excruciating. You begin to question how you are going to make it all the way through, and furthermore, question why you would want to. But after a non-specific measurement of time (lets just say, fifteen minutes), you begin to get used to this visual and eventually you don’t even realise that you are reading subtitles or haven’t seen a single RGB pixel for almost two hours.
WHAT’S GOOD FOR THE EYE...
How does this fifteen minute rule apply to sound? Essentially, it doesn’t. Sound works on a totally different cosmic level that I’m far too unqualified to write about. While it is true that you can become immersed in sound, you never casn never ignore it when it’s too loud or of poor quality. One of the most common tips given to independent filmmakers, is to spend most of your budget on sound; as people will forgive a grainy picture, but people never forgive poor sound. And I’m sure I don’t need to sell anybody
reading this magazine on that point.
GOTTA HAVE SUBSTANCE
This of course does not mean that a stunning visual has no place; far from it. It just needs to be accompanied by something of substance. If your show / movie / event / presentation is able to keep the audience’s attention, then your visuals will hit their mark even greater. If your visuals are expected to carry the entire event, you wanna hope it doesn’t run any longer than fifteen minutes.
In my time writing for AV Magazine, the most impressive spectacle I have been lucky enough to witness was the Audio Visual set design for the Melbourne production of Hairspray. The LED screens gave creation to the most visually excitable thing I’ve seen on a theatre stage, yet the production had enough substance to keep my attention well after I stopped swooning over the set. It was probably the most obvious, real and tangible example of the fifteen minute rule I’ve experienced first hand. The visuals blew me away, but the substance of the production made the overall experience so much more memorable and because of that, I still have vivid memories of the visuals.
So the next time you are about to deck out your cinema room, or are deciding between the 50 inch and the 55 inch television, or are trying to spruce up your client’s shareholder meeting, keep these tips in mind:
- It is possible to use A/V to ‘polish a turd’ (as they say), but it can only be polished for about fifteen minutes.
- If your show is a turd... make sure the sound isn’t shit.
