Parts Information

shipment on a C.O.D. or pre-payment (check or creditcard) basis.

TermsNormal terms are pre-paid. Net-30 Days applies toonly those firms having pre-established accounts withCrown. If pre-paying, the order must be packed andweighed before a total bill can be established, afterwhich an amount due will be issued and shipmentmade upon receipt of pre-payment. New parts re-turned for credit are subject to a 10% re-stocking fee,and authorization from the Crown Parts Departmentmust be obtained before returning parts for credit.

Crown is not a general parts warehouse. Parts sold bythe Crown Parts Department are solely for servicingCrown/Amcron products. Part prices and availabil-ity are subject to change without notice.

General InformationLater sections include both mechanical and electricalparts lists for this product. The parts listed are currentas of the date printed. Crown reserves the right tomodify and improve its products for the benefit of itscustomers.

Part Numbering SystemsAs of the printing of this manual, Crown is using twonumbering systems. The elder system always useseight characters. The first character is a letter. Com-mon letters used are C, D, H, M, P, and Q. The secondthrough sixth characters are numbers. The numbersbuild sequentially (for each prefix letter) as new partsare added to our parts inventory system. (In somecases there will be a space then a four characternumber after the prefix letter; the space is considereda character.) The seventh character is usually a hy-phen, though it may be a letter to indicate a revision orspecial note. The last character is called a check-digit,and is useful to Crown for internal tracking.

Crown is in the process of converting to a new partnumber system. Length may vary from eight to twelvecharacters. There is still a letter prefix, then fivenumbers. These five numbers identify a type of part.The seventh character is a hyphen. Remaining char-acters identify the details of the type of part identifiedby the first part of the number.

Standard and Special PartsMany smaller electrical and electronic parts used byCrown are stocked by and available from electronicsupply houses. However, some electronic parts thatappear to be standard are actually special. A partordered from Crown will assure an acceptable re-placement. Structural items such as modules andpanels are available from Crown only.

Theory

OverviewIt should be noted that over time Crown makes im-provements and changes to their products for variousreasons. This manual is up to date as of the time ofwriting. For additional information regarding theseamplifiers, refer to the applicable Technical Notesprovided by Crown for this product.

This section of the manual explains the general opera-tion of a Macro-Tech 3600VZ power amplifier. Topicscovered include Front End, Grounded Bridge, ODEP,and VZ supply. Due to variations in design fromvintage to vintage (and similarities with other Crownproducts) the theory of operation remains simplified.

FeaturesMacro Tech amplifiers utilize numerous Crown innova-tions including grounded bridge and ODEP technolo-gies. Cooling techniques make use of the what isessentially air conditioner technology. Air flows bot-tom to top, and front to side. Air flows a short distanceacross a wide heatsink. This type of air flow providessignificantly better cooling than the “wind tunnel”technology used by many other manufacturers. Out-put transistors are of the metal can type rather thanplastic case. This allows for a significantly higherthermal margin for the given voltage and currentratings. All devices used are tested and graded toensure maximum reliability. Another electronic tech-nique used is negative feedback. Almost all poweramplifiers utilize negative feedback to control gainand provide stability, but Crown uses multiple nestedfeedback loops for maximum stability and greatlyimproved damping. Most Crown amplifiers have damp-ing in excess of 1000 in the bass frequency range. Thisfeedback, along with our compensation and ultra-lowdistortion output topology, makes Crown amplifierssuperior.

Features specific to the Macro Tech Series’ includetwo seperate power transformers (one for each chan-nel), a full time full speed fan which also serves as thelow voltage transformer, slew rate limiting, and audiomuting for delay or protective action. This amplifiercan operate in either a Bridged or Parallel Mono modeas well as dual (stereo). A sensitivity switch allowsselection of input voltage required for rated output.Level controls are mounted on the front panel and areof the rotary type. Front panel indicators let the userknow the status of the low voltage power supply(enable), an ODEP indicator for each channel whichshows the reserve energy status, and a SPI/IOC

indicator for each channel which indicates signaloutput and distortion. In general, the packaging of thismodel is designed for maximum watt/price/weight/size value with user friendly features.

For additional details refer to the specification section,or to the applicable Owner’s Manual.

Front End OperationThe front end is comprised of three stages: BalancedGain Stage (BGS), Variable Gain Stage (VGS), andthe Error Amp. Figure 1 shows a simplified diagram ofa typical front end with voltage amplification stages.

Balanced Gain Stage (BGS)Input to the amplifier is balanced. The shield may beisolated from chassis ground by an RC network tointerrupt ground loops via the Ground Lift Switch. Thenon-inverting (hot) side of the balanced input is fed tothe non-inverting input of the first op-amp stage. Theinverting (negative) side of the balanced input is fedto the inverting input of the first op-amp stage. Apotentiometer is provided for common mode rejectionadjustment. Electrically, the BGS is at unity gain.(From an audio perspective, however, this stageactually provides +6dB gain if a fully balanced signalis placed on its input.) The BGS is a non-invertingstage. It’s output is delivered to the Variable GainStage.

Variable Gain Stage (VGS)From the output of the BGS, the signal goes to the VGSwhere gain is determined by the position of the Sen-sitivity Switch, and level is determined by the levelcontrol. VGS is an inverting stage with the input beingfed to its op-amp stage. Because gain after this stageis fixed at 26dB (factor of 20), greater amplifier sensi-tivity is achieved by controlling the ratio of feedback toinput resistance. The Sensitivity Switch sets the inputimpedance to this stage and varies the gain such thatthe overall amplifier gain is 26 dB, or is adjustedappropriately for 0.775V or 1.4V input to attain ratedoutput.

Error AmpThe inverted output from the VGS is fed to the non-inverting input of the Error Amp op-amp stage throughan AC coupling capacitor and input resistor. Amplifieroutput is fed back via the negative feedback (NFb)loop resistor. The ratio of feedback resistor to inputresistor fixes gain from the Error Amp input to theoutput of the amplifier at 26 dB. Diodes prevent

Theory

overdriving the Error Amp. Because the Error Ampamplifies the difference between input and outputsignals, any difference in the two waveforms willproduce a near open loop gain condition which in turnresults in high peak output voltage. The output of theError Amp, called the Error Signal (ES) drives theVoltage Translators.

Voltage AmplificationThe Voltage Translator stage separates the output ofthe Error Amp into balanced positive and negativedrive voltages for the Last Voltage Amplifiers (LVAs),translating the signal from ground referenced ±15V to±Vcc reference. LVAs provide the main voltage ampli-fication and drive the High Side output stages. Gainfrom Voltage Translator input to amplifier output is afactor of 25.2.

Voltage TranslatorsA voltage divider network splits the Error Signal (ES)into positive and negative drive signals for the bal-anced voltage translator stage. These offset referencevoltages drive the input to the Voltage Translatortransistors. A nested NFb loop from the output of theamplifier mixes with the inverted signal riding on theoffset references. This negative feedback fixes gain atthe offset reference points (and the output of the ErrorAmp) at a factor of -25.2 with respect to the amplifieroutput. The Voltage Translators are arranged in acommon base configuration for non-inverting voltagegain with equal gain. They shift the audio from the±15V reference to VCC reference. Their outputs drivetheir respective LVA.

Also tied into the Voltage Translator inputs are ODEP

limiting transistors and control/protection transistors.The ODEP transistors steal drive as dictated by theODEP circuitry (discussed later). The control/protec-tion transistors act as switches to totally shunt audio toground during the turn-on delay, or during a DC/LF orFault protective action.

Last Voltage Amplifiers (LVAs)The Voltage Translator stage channels the signal tothe Last Voltage Amplifiers (LVA's) in a balancedconfiguration. The +LVA and -LVA, with their push-pulleffect through the Bias Servo, drive the fully comple-mentary output stage. The LVAs are configured ascommon emitter amplifiers. This configuration pro-vides sufficient voltage gain and inverts the audio. Thepolarity inversion is necessary to avoid an overallpolarity inversion from input jack to output jack, and itallows the NFb loop to control Error Amp gain byfeeding back to its non-inverting input (with its polarityopposite to the output of the VGS). With the addedvoltage swing provided by the LVAs, the signal thengains current amplification through the Darlingtonemitter-follower output stage.

Grounded Bridge TopologyFigure 2 is a simplified example of the groundedbridge output topology. It consists of four quadrantsof three deep Darlington (composite) emitter-followerstages per channel: one NPN and one PNP on theHigh Side of the bridge (driving the load), and oneNPN and one PNP on the Low Side of the bridge(controlling the ground reference for the rails). Theoutput stages are biased to operate class AB+B forultra low distortion in the signal zero-crossing regionand high efficiency.

High Side (HS)The High Side (HS) of the bridge operates much likea conventional bipolar push-pull output configuration.As the input drive voltage becomes more positive, theHS NPN conducts and delivers positive voltage to theload. Eventually the NPN devices reach full conduc-tion and +Vcc is across the load. At this time the HSPNP is biased off. When the drive signal is negativegoing, the HS PNP conducts to deliver -Vcc to the loadand the HS NPN stage is off.

The output of the +LVA drives the base of predriverdevice. Together, the predriver and driver form thefirst two parts of the three-deep Darlington and arebiased class AB. They provide output drive throughthe bias resistor, bypassing the output devices, atlevels below about 100mW. An RLC network betweenthe predriver and driver provide phase shift compen-sation and limit driver base current to safe levels.Output devices are biased class B, just below cutoff.At about 100mW output they switch on to conduct highcurrent to the load. Together with predriver and driver,the output device provide an overall class AB+Boutput.

The negative half of the HS is almost identical to thepositive half, except that the devices are PNP. Onedifference is that the PNP bias resistor is slightlygreater in value so that PNP output devices run closerto the cutoff level under static (no signal) conditions.

This is because PNP devices require greater drivecurrent.

HS bias is regulated by Q18, the Bias Servo. Q18 is aVbe multiplier which maintains approximately 3.3VVce under static conditions. The positive and negativehalves of the HS output are in parallel with this 3.3V.With a full base-emitter on voltage drop acrosspredrivers and drivers, the balance of voltage resultsin approximately .35V drop across the bias resistors inthe positive half, and about .5V across the bias resistorin the negative half. Q18 conduction (and thus bias) isadjustable.

A diode string prevents excessive charge build upwithin the high conduction output devices when off.Flyback diodes shunt back-EMF pulses from reactiveloads to the power supply to protect output devicesfrom dangerous reverse voltage levels. An outputterminating circuit blocks RF on output lines fromentering the amplifier through its output connectors.

Low Side (LS)The Low Side (LS) operates quite differently. Thepower supply bridge rectifier is not ground refer-enced, nor is the secondary of the main transformer.In other words, the high voltage power supply floatswith respect to ground, but ±Vcc remain constant withrespect to each other. This allows the power supply to


10

deliver +Vcc and -Vcc from the same bridge rectifierand filter as a total difference in potential, regardlessof their voltages with respect to ground. The LS usesinverted feedback from the HS output to control theground reference for the rails (±Vcc). Both LS quad-rants are arranged in a three-deep Darlington and arebiased AB+B in the same manner as the HS.

When the amplifier output swings positive, the audio isfed to an op-amp stage where it is inverted. Thisinverted signal is delivered directly to the bases of thepositive (NPN) and negative (PNP) LS predrivers. Thenegative drive forces the LS PNP devices on (NPNoff). As the PNP devices conduct, Vce of the PNPDarlington drops. With LS device emitters tied toground, -Vcc is pulled toward ground reference.Since the power supply is not ground referenced (andthe total voltage from +Vcc to -Vcc is constant) +Vccis forced higher above ground potential. This contin-ues until, at the positive amplifier output peak, -Vcc =0V and +Vcc equals the total power supply potentialwith a positive polarity. If, for example, the powersupply produced a total of 70V from rail to rail (±35VDCmeasured from ground with no signal), the amplifieroutput would reach a positive peak of +70V.

Conversely, during a negative swing of the HS outputwhere HS PNP devices conduct, the op-amp wouldoutput a positive voltage forcing LS NPN devices toconduct. This would result in +Vcc swinging towardground potential and -Vcc further from ground poten-tial. At the negative amplifier output peak, +Vcc = 0Vand -Vcc equals the total power supply potential witha negative polarity. Using the same example as above,a 70V supply would allow a negative output peak of -70V. In summary, a power supply which produces atotal of 70VDC rail to rail (or ±35VDC statically) iscapable of producing 140V peak-to-peak at the ampli-fier output when the grounded bridge topology isused. The voltage used in this example are relativelyclose to the voltages of the PB-1/460CSL.

The total effect is to deliver a peak to peak voltage tothe speaker load which is twice the voltage producedby the power supply. Benefits include full utilization ofthe power supply (it conducts current during bothhalves of the output signal; conventional designsrequire two power supplies per channel, one positiveand one negative), and never exposing any outputdevice to more than half of the peak to peak outputvoltage (which does occur in conventional designs).

Theory

Low side bias is established by a diode string whichalso shunts built up charges on the output devices.Bias is adjustable via potentiometer. Flyback diodesperform the same function as the HS flybacks. Theoutput of the LS is tied directly to chassis ground viaground strap.

Output Device Emulation Protection (ODEP)To further protect the output stages, a specially devel-oped ODEP circuit is used. It produces a complexanalog output signal. This signal is proportional to thealways changing safe-operating-area margin of theoutput transistors. The ODEP signal controls the Volt-age Translator stage by removing drive that mayexceed the safe-operating-area of the output stage.

ODEP senses output current by measuring the volt-age dropped across LS emitter resistors. LS NPNcurrent (negative amplifier output) and +Vcc aresensed, then multiplied to obtain a signal proportionalto output power. Positive and negative ODEP voltagesare adjustable via two potentiometers. Across ±ODEPare a PTC and a thermal sense (current source). ThePTC is essentially a cutoff switch that causes hardODEP limiting if heatsink temperature exceeds a safemaximum, regardless of signal level. The thermalsense causes the differential between +ODEP and –ODEP to decrease as heatsink temperature increases.An increase in positive output signal output into a loadwill result in –ODEP voltage dropping; an increase innegative output voltage and current will cause +ODEPvoltage to drop. A complex RC network between the±ODEP circuitry is used to simulate the thermal barri-ers between the interior of the output device die(immeasurable by normal means) and the time delayfrom heat generation at the die until heat dissipates tothe thermal sensor. The combined effects of thermalhistory and instantaneous dynamic power level resultin an accurate simulation of the actual thermal condi-tion of the output transistors.

VZ PowerVZ means Variable Impedance and is the name ofCrown's patented articulated power supply technol-ogy. It enables Crown to pack tremendous power intojust 3½ inches of vertical rack space.

BackgroundA power supply must be large enough to handle themaximum voltage and current necessary for the am-plifier to drive its maximum rated power into a speci-fied load. In the process of fulfilling this requirement


11

conventional power supply designs produce exces-sive heat, are heavy, and take up precious real estate.It's no secret that heat is one of a power amplifiersworst enemies.

According to Ohm's Law, the bigger the power sup-ply, the more heat the power transistors must dissi-pate. Also, the lower the resistance of the powertransistors, the more voltage you can deliver to theload. But at the same time that you lower the resis-tance of the transistors, you increase the currentpassing through them, and again increase the amountof heat they must dissipate.

The VZ supplyAn articulated power supply, like VZ, can circumventmuch of this problem by reducing the voltage appliedto the transistors when less voltage is required. Re-ducing the voltage reduces the heat. Since the ampli-fier runs cooler, you can safely pack more power intothe chassis.

The VZ supply is divided into segments to bettermatch the voltage and current requirements of thepower transistors. Remember that audio signals likemusic are complex waveforms.

For music the average level is always much less thanthe peak level. This means a power supply does notneed to produce full voltage all the time.

The VZ supply is divided into two parts. When thevoltage requirements are not high, it operates in aparallel mode to produce less voltage and morecurrent. In this mode the power transistors stay coolerand are not forced to needlessly dissipate heat. Thisis the normal operating mode of the VZ power supply.

Theory

When the voltage requirements are high the VZ supplyswitches to a series mode to produce the highervoltage and less current. The amplified output signalnever misses a beat and gets full voltage when itneeds it—not when it doesn't need it.

Sensing circuitry watches the voltage of the signal todetermine when to switch modes. The switching cir-cuitry is designed to prevent audible switching distor-tion to yield the highest dynamic transfer function—you hear only the music and not the amplifier. You getnot only the maximum power with the maximum safety,you also get the best power matching to your load.

VZ Switch ControlThe two halves of U03 form identical comparators thatmonitor the available voltage of DC supply V2 andcompare it to the output voltage of the amplifier. Whena positive going output voltage exceeds a predeter-mined ratio of the available supply voltage, U03 pin 1produces a low voltage triggering U04. When trig-gered, the "Q" output of U04 changes from low to highdriving the gates of FET's Q00, Q01, and Q02. Theother half of U03 (pin 7) reacts to negative goingoutput voltage. Both halves of U03 receive V2 andamplifier output voltage differentially.

The time constant set by C18 and R16 on the input ofU04 sets the maximum switch frequency of the sup-ply. This time constant forces the supply to stay in theseries mode regardless of amplifier condition for 200ms. The reset pin of U04 (pin 4) forces the output ofU04 low when FET damage conditions exist.

C16 and C17 provide hysteresis around the compara-tors of U03 to insure stable operation.

VZ Protection CircuitProtecting high current transistors can be trouble-some in circuits that do not provide convenient currentsample points. FETs Q00-Q02 fall into this class ofproblems, but protection has been designed basedon the following two conditions being present at thesame time:

•Higher than normal on-state drain to source voltage•Gate drive present.

When both of these conditions exist, a reasonableassumption can be made that the FETs are operatingin an area that if sustained will cause damage to theFETs. These two conditions are detected by U05 pins5 and 7.

U05 detects gate drive to the FETs at pin 7. Pin 6 is areference input with the reference voltage set by R22in series with R19.

U05 detects excessive source to drain voltage on theFETs at pin 5. R17 in series with R18 forms a voltagedivider to pin 5 of U05. The reference is set by avoltage divider formed by R29, R20, and R22.

When both conditions are detected the outputs of U05(pins 1 and 2) allow C20 to start charging through R23.After 20µS, C20 will be sufficiently charged to turn onthe section of U05 whose output is pin 14, dischargingC21. As C21 discharges, it turns on Q03 which pullsthe non-inverting input low (pin 9). U05 pin 13 drivesthe reset pin of U04 low which removes gate drive fromthe FETs. This hysteresis makes the circuit auto-resetting. Every 10ms (set by C21 and R26) it will makeanother 20µs try at driving the FETs. R25 prevents Q03from pulling the input of U05 below its negativesupply.

Electrical Checkout Procedures

General InformationThe following test procedures are to be used to verifyoperation of this amplifier. DO NOT connect a load orinject a signal unless directed to do so by the proce-dure. These tests, though meant for verification andalignment of the amplifier, may also be very helpful introubleshooting. For best results, tests should beperformed in order.

All tests assume that AC power is from a regulated 120VAC source. Test equipment includes an oscillo-scope, a DMM, a signal generator, loads, and I.M.D.and T.H.D. noise test equipment.

Standard Initial ConditionsLevel controls fully clockwise.Stereo/Mono switch in Stereo.Sensitivity switch in 26 dB fixed gain position.It is assumed, in each step, that conditions of theamplifier are per these initial conditions unless other-wise specified.

Test 1: DC OffsetSpec: 0 VDC, ±5 mV.Initial Conditions: Controls per standard, inputs shorted.Procedure: Measure DC voltage at the output connec-tors (rear panel). There is no adjustment for outputoffset. If spec is not met, there is an electrical malfunc-tion. Slightly out of spec measurement is usually dueto U104/U204 out of tolorance.

Test 2: Output Bias AdjustmentSpec: 310 ±10 mVDC.Initial Conditions: Controls per standard, heatsink tem-perature less than 40°C.Procedure: Measure DC voltages on the output moduleacross R02, adjust R26 if necessary. Measure DCvoltages on the output module across R21, adjust R23if necessary. Repeat for second channel.

Test 3: ODEP Voltage AdjustmentSpec: Bias Per Chart, ±0.1V DC.Initial Conditions: Controls per standard, heatsink atroom temperature 20 to 30°C (68 to 86°F). Note: Thisadjustment should normally be performed within 2minutes of turn on from ambient (cold) conditions. Ifpossible measure heatsink temperature, if not mea-sure ambient room temperature. Use this informationwhen referencing the following chart.
