Eclipse HX E-MADI 64 card

2

MADI stands for Multi-channel Audio Digital Interface.

It is a 32, 56 or 64 channel, synchronous AES3 digital audio pipe running over Fiber or Co-axial cable between compatible devices.

Also known as AES10. It is used in the Audio and Video Broadcasting, Live Performance and Recording

industries.

What is MADI? Cont.Audio routers (or console) can route audio from any port on the audio network to and from the intercom matrix via the E-MADI connection.

The E-MADI card in the matrix appears as 64 virtual direct audio ports

MADI ports can used in the same manner as 4-wire direct ports. IFB sources/destinations, members of PartyLines etc.

Sample rate / Channel Qty Options

► 32 Channels – 44.1KHz, 48KHz and 96KHz.► 56 Channels – 44.1KHz and 48KHz.► 64 Channels – 44.1KHz and 48KHz.

► EHX (& ECS) can limit MADI ports to 16, 32, 56 and 64 ports

► The E-MADI card routes up to 64 channels of audio via the MADI interface.

► Each audio channel is 24 bits in length.

► The MADI card provides an input and output gain for each MADI channel which is configurable in HX and PM Pro

► For each channel the input and output gain can be configured to be between -72dB to +18dB.

► Each channel has inbuilt VOX and noise gate circuitry, similar to MVX

MADI Audio

8

Each MADI input channel will provide its 4-character channel ID via the provided embedded data bits.

(this is displayed on the panel key or sent to/from the 3rd party madi unit)

Each MADI output channel’s ID can be re-labeled by the Eclipse HX configuration or through PM Pro alias labels.

This means that Eclipse HX Panels can automatically show the MADI channel ID or Alias as supplied from Production Maestro Pro.

HX label choices are

Use Remote 3rd party ID (4-character)

Use Production Maestro Pro Alias instead

Disable ID – use HX port name.

MADI Channel Labelling

9

The correct frame position for the MADI cards in the frame is directly after the MVX cards, and before the E-Que, IVC-32, LMC-64 and E-FIB fibre cards.

As many E-Madi cards can be fitted into a matrix as you need as long you do not exceed the matrix port count

Use HX auto-discovery or manually set the card slot

All MADI channels have standard HX settings, including VOX and in-use tally

Card Properties are only used when not using word clock and allows sample rate selection when syncing to video signals.

Apply the changes to the frame(s) with a reset.

When using the Word Clock Source Sync input:

Connect the clock source input

WRD LED on the front of the E-MADI card will light solid green to indicate it has detected the word clock

The E-MADI card will display the number of ports configured, and detected receive sample rate (as provided by word clock) with flashing green LEDS 1:1 at 0.5Hz

The E-MADI card front Red Error light will remain lit solidly until MADI source audio is detected.

Note each E-Madi card must be feed it’s own word clock sync input signal

If using a Video Source Sync input:

Connect the clock source input

VID LED on the front of the E-MADI card will light solid green to indicate it has detected the video clock

The MADI card will display the number of ports and sample rates configured in HX, with flashing green LEDS 1:1 at 0.5Hz

The E-MADI card front Red Error light will remain lit solidly until MADI audio is detected.

Suggest using a world clock distribution unit like the :

Apogee – “Big Ben” product (1 in / 6 out)

Video / World Clock sync input

15

Connect the external MADI Audio (using Coax or Fiber)

Connect the external MADI Audio to the rear of the E-MADI card.

The E-MADI card will display the number of ports configured and detected sample rate (provided by word clock*) with a solid green LED on the front of the E-MADI card if they match the received source.

The Red Error light will turn off on the front of the E-MADI card when the MADI source is detected.

Audio passes in and out of the E-MADI card to the Eclipse HX backplane

*If using a video signal then the HX sample rate is displayed.

MADI Audio Connection

On an active E-MADI card with no connections:

Power LEDs will illuminate solid green

Active LED will flash green 1:1 at 0.5Hz

Red Error LED will illuminate solid.

On an active E-MADI card with MADI connections and clock source:

The Red Error light will turn off on the front of the E-MADI card when the MADI source is detected.

Sample rate LEDs on the front of the E-MADI card will flash between 2 types of sample rates when the received sample rate differs from the transmit sample rate.

Channel LEDs on the front of the E-MADI card will flash between 2 types of port numbers when the number of received channels differs from the channel number set by HX.

BOOT sequenceActive and Error LEDs will flash rapidly until completed.If there are any POST messages these LEDs will not flash at 0.5Hz 1:1 and will

indicate error codes – see card manual for details.

Event Log records channel and sample rate settings for each E-MADI64 card.

Firmware report is provided on the Project or Layout screen. As part of the firmware report

E-MADI Diagnostics

18

E-MADI cards are centrally (HX) or locally upgradeable.

Go to the Layout screen and right mouse click on the Matrix and select update firmware /

card update. Follow instructions.

The FPGA, CPU App and DSP code can be centrally upgraded but not the CPU Boot code.

The HX sends code rapidly to the CPU but it can take up to 18 minutes to load the FPGA on

the E-MADI card from the CPU, (DSP takes just 3 min and CPU app 1 min). During this

upgrade time the E-MADI will continue to transmit MADI but not receive MADI. * Do not

make any map downloads during this time

The Event Logs report start and finish update and firmware versions.

The Xilinx PROM holds a golden image of the FPGA and an image that is upgradable.

Therefore as the CPU boot code can not be modified, if the upgrade is inadvertently

terminated the card is always recoverable via HX.

Xilinx local update through an attached PC and correct cable is faster.

Hands On Practice SessionThe purpose of this session is to gain familiarity with E-MADI by configuring a card to provide some of the more common functions. We can loop the MADI back into the Frame so we can test what we have set up.

Install the Physical Card into the Eclipse HX Frame

Set up the Card to Run at 48kHz, with 64 channels in HX

Connect the Word Clock Device to the Card using Coax Cable

Connect the Fibre MADI port to itself using a loopback Fibre Cable

Set up the first 4 MADI ports in HX to operate with:Port 1. Global IFB with -15dB cutPort 2. Global Latch DisablePort 3. Audio Presence Tally EnabledPort 4. Labels set to PM and HCI

Program a panel to have talk and listen keys to the 4 ports you have set up
