IMAX AM4 Power Amplifier
M1371 THE INPUT SECTION
The input board processes the audio signal from the input jacks to the indicator/control board,
(M1370) on the front panel.
Each channel consists of a balanced gain stage, subsonic filter, and a stereo / mono switch.
Looking at the left channel, the balanced input, (XLR Jack) and input (phone jack) are wired
in parallel to the input of a balanced operational amplifier, (U2:B). The gain of this stage is 0.82
(-1.3dB) balanced and 1.6 (4.0dB) unbalanced. Resistors R1, R3 along with capacitors C3 and
C4 form a radio interference elimination filter.
The subsonic filter provides a 20Hz high pass filter. The filter consists of a tee network on
the input of U2:A along with R13, R19, C6 and C8. The gain is 1 (0dB) in the passband, (above
20 Hz).
The audio signals from the input board M1371 pass through the 14 conductor cable and the
16 conductor DIP cable to the front panel board M1370.
M1370 FRONT PANEL BOARD AND LIMITERS
This board contains:
 the front panel indicating LEDs (signal and clip).
Circuit Explanation:
 The left channel of the circuit is explained. (Refer to the schematic of M1370 as the sections
of the circuit are explained.)
 The audio signal out of M1371 passes through the front panel board and then enters U1:A
through pin 2. U1:A is set for a gain of 1 (0dB)
The AM4's limiter is built around U2:A&B and U1:B. When clipping is detected in the amplifier a signal is
fed to ACLIP. The current from ALIM acts to increase the gain of U2 and this audio voltage gets subtracted
from the signal on the input and less signal appears on the output of U1:B. Transistors Q5C and Q6C
along with the surrounding passive parts provide the attack and release time constants. When an audio
signal on the output of the power amplifier section enters clipping, pulses representing the duration of the
clipped portion appear at ACLIP. These pulses turn on transistor Q6C, and Q6C provides current pulses to
turn on clip LED LD6C. The pulses also pass through R7C and D6C to charge C3C and C36C. When the
voltage across C3C reaches 0.5 volts then Q5C turns on providing a current into pins 1 and 16 of U2
limiting the audio signal at U1:B. The charging (attack) and discharging (release) times of the limiter are
30mS and 0.5 seconds respectively. Resistors R50C and R7C provide the charging path, and resistor
R51C provides the discharge path.
The Signal LED circuit consists of Q1C and the surrounding circuitry. The audio signal
enters the activity LED circuit through R2C. R2C and C21C form a differentiator that turns Q1C
on illuminating the activity LED whenever the audio signal increases in amplitude. A constant
current flows through R55AC, R55BC and when Q1C is off, the collector current then flows
through D1C. From M1371 the audio signal passes through a 12-conductor ribbon cable to
circuit board M1370.

On M1370 an operational amplifier U3A:B re-references the ground for the audio signal from
LVGND to the corresponding GNDB (left output ground) or (right output ground). U3A:B also
provides DC correction for DC offsets appearing on the output binding posts. Feedback from the
output binding posts appears through R54B or R60&61B where the DC offset achieves a gain of -1
from U3A:B. The DC offset of opposite polarity on the output of U3A:B will compensate for the DC
offset in the amplifier section on M1370 resulting in 0 volts DC on the output binding posts.
M1370 The Voltage Amplifier and Current Amplifier
This board contains:
 a voltage amplifier section
 a current amplifier section
 amplifier current limit section
 heatsink temperature sensing
Voltage Amplifier Section
The voltage amplifier amplifies the audio signals voltage from 6.8 volts peak (at the output of U3A:B) to
approximately 98v peak, which is required to drive the current amplifier section. The current amplifier
provides the current required for the 98v peak signal to drive 1200 watts into 4 ohms out of the binding
posts. Before the circuit is described in detail here is a quick rundown on the signals path through the
voltage amplifier stage. Refer to the schematic of M1370. Lets consider that a positive going AC signal is
present at pin7 of U3A:B. The positive going signal will turn on the positive side of the voltage amplifier. The
signal at the input turns on Q7B (through R57B, D11B and D12B). The collector of Q7B pulls down on the
base of Q10B turns this transistor on further and allows a greater current to flow out of Q10Bs collector.
This increase in current passes through Q11B and its collector to emitter voltage decreases. The collector
of Q11B now being more positive in voltage turns the base of Q17B on causing an increase in Q17Bs
collector current resulting in the output of the voltage amplifier (net00156) going positive. As the positive
side of the amplifier was turning on the negative side would have been turning off. This is how the output
was able to move positive following the input signal. The reverse would hold true if a negative going signal
were present on the input of the voltage amplifier.
Circuit Description
The voltage amplifier is a mirrored image with circuitry connected to the positive power supply rail being
identical (but opposite polarity) to the circuitry connected to the negative power supply rail. For this reason
we will look in detail at the positive side of the amplifier. The audio signal enters the voltage amplifier. The
signal passes through R57B, D11B and D12B to the base of Q7B. Diodes D11B and D12B set up the DC
bias on Q7B to approximately 0.6 mA. The first voltage gain stage consists of Q7B along with the resistor
chain on its collector and the emitter resistor (R66B). Transistor Q7B drives the base of Q10B through the
resistor chain. A DC current of approximately 4 mA should flow through the collector of Q10B. The voltage
drop across Q10B remains constant and is derived from the voltage drop across the voltage reference
Q15B, resistor R77B, and the base/emitter junction of Q11B. This total voltage should equal a roximately 3 VDC.
Transistor Q10B is the second gain stage and its out ut current flows through Q11B. Transistor Q11B is a common
base stage with the collector driving the base of out ut buffer Q17B. Diode D20B is a clam ing diode that revents the
maximum eak of the audio signal from coming within 4V of the 144 VDC rail. This is to revent the out ut current
am lifier from going into saturation during cli ing and therefore having storage delay roblems. Transistor Q17B
buffers the high im edance resent on the collector of Q11B. The out ut of the buffer rovides a low out ut im edance
at the junction of R83B and R84B and is current limited to 30mA through the clam ing action of D17B, D18B and
D19B. The signal at the junction of R83B and R84B drives the succeeding current am lifier.

Current Amplifier Section
The current amplifier receives a high voltage audio signal from the voltage amplifier and provides the
current drive necessary to drive speaker cabinets. The current amplifier is a two-tier complimentary output
driver design controlled by a complimentary darlington stage.
[CIRCUIT DESCRIPTION - REFER TO THE SIMPLIFIED SCHEMATIC #1]
Quiescent Condition
This design is class A/B and therefore the output driver transistors must be forward biased to provide low
crossover distortion. In most class A/B designs, a diode chain or VBE multiplier is used to control the bias
voltage and provide a means of adjusting the bias. This design is different, as there isnt a diode chain or
VBE multiplier. For simplicity lets consider only the positive side of the current amplifier, that is all parts
between the positive power supply rails and the audio signal output/input terminals. The negative side is
the same as the positive, except for polarity changes.
To bias Q35B, greater than 0.5V is needed from base to emitter, (or for simplicity from base
to amplifier output). Points A and B are at the same potential, so consider them to be
connected. If this is true then 0.5V from test point 2 to the amplifier output must appear across
R104B. There must be some way of developing this voltage across R104B, and there is using
the darlington (Q23B and Q25B) driver along with local feedback.
Simplified schematic #1 shows the biasing circuit. The current needed to develop 0.5V across
R104B comes from the emitter of Q25B. When the amplifier is first turned on the current source
(Q19B) turns on Q23B and Q25B and current flows through R104B developing a voltage. When this

voltage approaches 0.5V Q20B turns on and robs current from the base of Q23B. This causes Q23B
to turn off until the reduced current flowing through Q25B maintains 0.5V across R104B. Q20B will
turn off slightly causing Q23B and Q25B to increase their collector currents. The circuit reaches a
point of equilibrium with approximately 0.5V across R104B.
Because all output devices are not identical and base emitter voltages vary, some adjustment
must be available to slightly adjust the 0.5V across R104B. This is accomplished with RTB. RTB
causes Q20B to turn on slightly more or less resulting in Q23B and Q25B turning on slightly more or
less and therefore R104Bs voltage will be slightly more or less than 0.5v. The proper quiescent
current voltage is 4mV (to be measured between test points 8 and 9).
The Second Tier and Tier Switching
Refer to the simplified schematic Fig. #1 while reading the following text. One way of making an amplifier
more efficient is to vary the Power Supply Voltage on the collectors of the output transistors (Q35B &
Q36B). The lower the voltage from collector to emitter, the lower the device dissipation. During quiescent
conditions, there is 55VDC on the collectors of output transistors Q14 and Q22. The peak AC voltage that
can appear on the amplifiers output is approximately 139V peak. How can an output transistor deliver a
139V peak when its collector is only at 55VDC? It can if its collector is pulled up to 144VDC as the output
signals peak rises above 55VDC. Refer to Fig. #2. The second tier voltage must remain above the
amplifiers output voltage by amount Vm. Therefore the circuitry controlling the second tier voltage must
increase the tier voltage before the amplifiers output voltage reaches 55VDC. This leading voltage is
necessary to compensate for time lag of the second tier circuit during fast rising amplifier output signals.
The voltage between the amplifiers output and test point 4 is approximately 14VDC derived
from the voltage drop across ZD4B. We call this voltage the floating battery because it floats
on top of the output audio signal with test point 4 always being 14VDC greater than the peak of
the output signal. Test point 4 drives the gate of mos-fet Q32B. Q32B controls the transistors of
the upper tier. As Q32B turns on its source forward biases the base of Q33B and Q33B pulls the
collector of Q35B towards the 144 volt rail. The gate to source voltage needed to turn on Q32B
is approximately 3.5 volts. When the peak output signal is about 44.5vp (55v-(14v-3.5v)) then
Q32B will start to turn on the second tier. The second tier voltage will remain about 13 volts
(Vm) above the peak of the output signal to the point of clipping where this voltage is reduced to
about 6 volts (measured driving an 8 ohm load). Zener ZD10B protects the gate source junction
of Q11 and also provides a supply current path through R38 for the floating battery.

NOTE: The Power supply voltages given are those when the amplifier is not driving a speaker load.
This will allow you to check the tier switching with the cover of the amplifier off and the amplifier,
therefore, running cool.
Current Limit Protection Circuitry
To have an amplifier drive 3000 watts into practically any combination of speaker cabinets and know what
is a safe load and what is not is a very difficult task. An extensive amount of time was spent on the current
limit circuitry so that it may simulate the safe operating area of the output transistors (SOAR curve). No
matter how reactive the load may be the phase shift that it presents, along with its resistive component is
used to set the output current limit of the output transistor stage. Refer to the schematic of board M1370
while reading the following text. The current limit circuitry is a mirrored image with circuitry connected to the
positive power supply rail being identical (but opposite polarity) to the circuitry connected to the negative
power supply rail. For this reason we will look at the positive side of the circuitry.
Transistor Q46B measures the peak current flowing through resistor R146B. The voltage across
R146B (as a result of the current flowing through it) is scaled down by R173B, R167B, R134B,
R135B, R136B, D25B and D27B these parts make up the safe operating area along with the time
constants of C31B, R120B, C37B and R152B. Fig. #3 shows a waveform of the current that passes
through R146B and R147B when the output of the amplifier is shorted to ground. This can only be
seen by using an oscilloscope to measure differentially across R146B and R147B. The conditions of
the measurement are contained on the diagram. During current limit when Q46B turns on it reduces
the voltage across R119B. R119B is in series with a 20 volt zener (ZD7B) and is also in parallel with
the junction of Q29B. The current that flows through R110B, ZD7B, R119B, and R111B normally
saturates Q29B. When Q46B reduces the voltage across ZD7B and R119B to below 20.6 volts,
Q29B turns off allowing a charge to build up on C28B through resistors R116B and R118B. If current
limiting occurs for a long enough duration to allow C28B to charge to 1.2 volts then Q28B will turn on
tripping the relay circuit. As soon as the relay is tripped the audio signal will be turned off at the output
of the voltage amplifiers and will remain off for about 5 seconds before the relay turns on and allows
the audio signal to pass through the amplifier. If a current limit condition is still present then the whole
cycle will occur again and repeat until the load conditions on the amplifiers output are safe for the
amplifier. When a safe load appears the amplifier will automatically reset and drive that load (the
speaker cabinet).
DC Protection
If a DC voltage greater than 8 volts appears on the output of the amplifier for more than 200 milliseconds
then triac Q16 will turn on holding the output at ground potential. MBS4992 is a device that turns on at
either + or - 8 volts DC.

NOTE: Every time you replace blown output transistors on a M1370 board test the DC protection triac
with the following circuit.
Conditions of test:
A) Pass a 100Hz 25v peak signal through the M1370 board under test with no load connected
to the amplifier output.
B) Connect points 1 and 2 as shown in the diagram. The amplifier should go into protect mode
as the triac (if working) shorted the output of the amplifier to ground, and the amplifier goes
into current limit.
C) Disconnect the triac test circuit and allow the amplifier to complete its protect cycle.
D) Reverse connections 1 to 2 and 2 to 1 and test again. The same results as in B) should be
observed if the triac is working.
Only test the triac for one protect cycle as prolonged testing will heat the triac to a high temperature.
Shutdown Circuit, Fan Control Circuit and Soft Turn On Circuit
 The shutdown relay and its associated drive circuitry have two possible operating states.
 Amplifier on under normal operating conditions.
 Amplifier power switch has just been turned OFF/ON, or the amplifier is in current limit
protecting the amplifiers output transistors, or the amplifier has overheated.

Shutdown Circuit
Here is how the circuit accomplishes these functions. The relays normally closed contacts short the output
of the voltage amplifiers to ground when the power switch is off. When the power switch is turned on, the
relay remains off (normally closed) for about 6 seconds. C7 charges to 35V and results in Q1 turning off
allowing Q2 to turn on. As Q1 turns on, it connects the negative terminal of the relays coil (Pin 16) to
ground energizing the relay and opening the normally closed contacts. If prolonged current limiting occurs
on the amplifiers output transistors then D21B will be forward biased turning on Q28B (from its off state).
Now +144VDC appears on the collector of Q3 and through R21 and R23 turn on Q2 therefore turning off
Q1 by shorting its base emitter junction. Q1 turning off will turn the relay off and the normally closed
contacts (off state) will short the outputs of the voltage amplifiers to ground so as not to continuously stress
the amplifiers output transistors. A cycle now occurs. With the voltage amplifiers now disabled there is no
signal driving the output transistors (Q35A to Q44B). The current limit circuit protecting the output
transistors (Q35A to Q44B) turns off and D5B is not forward biased and Q3 turns off. Through Q1 and Q2
the relay is turned back on and the voltage amplifiers are now active again, driving the output transistors. If
current limiting still occurs, then the same cycle will occur. If the cause of current limiting (low impedance or
short on the speaker output terminals) has been removed, then the amplifier will continue to operate
normally. The third operation that the relay provides is overheat shutdown. If for some reason the fan
cannot keep the heat-sinks in a safe operating temperature area then the temperature sensing circuit will
deliver through ZD2 a positive current to turn Q2 on and turn Q1 off to turn off the relay and disable the
voltage amplifiers. When the fan has cooled down the temperature of the amplifier, then the signal through
ZD2 will disappear and the relay circuit will turn on the relay to resume normal operation. Anytime the relay
is in the protect mode (due to the abnormal states) then contact pin of the relay will illuminate LD1 (the
protect LED on the front panel).
Soft Turn On Circuit
To reduce the inrush current that flows through the line cord from the AC power source (typical with large
linear power supplies), a circuit provides a soft turn on function. When the power switch is turned on, the
current that initially flows through the primary of the transformer must flow through R27 and R29. These
are surgistors that reduce the peak inrush current flow. After about 500 milliseconds a relays contacts
short across the surgistors so that they are not stressed by the current flowing through them under normal
operation. A circuit consisting of Q13, Q14, C77, and the associated resistors provides the time delay for
the turn on cycle of the relay. The circuit is very similar to the shutdown time delay circuit. Refer to the
section on the shutdown circuit for a circuit description.
Fan Circuit
Looking at the schematic to board M1371, here is a quick explanation of the fan control circuit. There is a
temperature sensor (AS35) on each M1370 board. When the amplifier is first turned on, Q11 and Q23 are
off. The AS35 temperature sensors are configured as temperature controlled current sources. As either
temperature sensor begins to heat up, more current flows through D18 or D19 increasing the voltage drop
across R63 or R64. The hotter temperature sensor will provide more current than the cooler sensor and
therefore develop a higher voltage across its associated 13K resistor. The higher voltage will forward bias
D18 or D19 reverse biasing the cooler temperature sensors diode so that the hotter sensor will control the
fan speed. At 40 degrees C there is 10 volts across R63 or R64 which is enough to turn on Q23 and Q11
providing 10 DC volts to the fan. Further heating the temperature sensors results in a larger DC voltage
across the fan. To lower the dissipation of Q11, D11 and D12 form a full wave rectifier in series with Q11.
The DC filtering is provided at the output of Q11. The maximum fan voltage is 28 VDC. D20 and R70
provide a current limiting function.
Thermal Shutdown Circuit
The ZD2 is the measuring point for the shutdown voltage. As the temperature sensing devices (AS35) that
control the fan circuit heat up the voltage on ZD2 rises until at 85 degrees Celsius on the M1370 heat-

sinks. The voltage reaches 33.6 (85 degrees C) VDC and the amplifier must be shutdown to protect the
output power transistors. ZD2 becomes forward biased and Q2 turns on turning the relay off and muting
the audio signal. After the amplifier cools down the voltage will decrease until Q2 turns off turning the relay
back on enabling the amplifier.
Identifying Defective Boards in the AM4
STEP 1: Visual Inspection of Front Panel and Fan
 Check to see whether the green power LED is lit. If not, the amplifier has a power supply
(M1371 board), transformer, A.C. switch or line cord problem.
 If the red protect LED stays on or samples off and on, this usually indicates a problem with
the voltage amplifier or current amplifier sections on one or both of the M1370 boards. Check
for misaligned pin connections or see if the ribbon cables have been cut or pinched through
their insulation.
 If the fan is running at full speed at power up this usually indicates a problem with the fan
circuitry on the M1371 board, but it can also be caused by M1370 circuit problems. A
damaged AS35 temperature sensor located under the M1370 heat-sinks can cause erratic fan
behavior.
 No output on either or both channels could be caused by intermittent push switches on the
input board.
STEP 2: Visual Inspection of Internal Chassis and Initial Testing
After removing the lid, look for any signs of smoke, charring or burnt components. Before powering up
replace the burnt components, and check the associated circuitry for damaged parts. Disconnect one
M1370 board and test one board at a time to reduce the possibility of further damage. Use a variac to
slowly increase the AC voltage up from 0 volts while monitoring the quiescent current with a meter and the
speaker output with an oscilloscope. Watch the speaker output for large DC offsets, or oscillation. Watch
the meter for large collector currents flowing. Remember under quiescent conditions, there should only be
3 to 5 millivolts across test points 8 and 9 on the output stage of the amplifier.
