structure differs from the design used untill now. This is due to the breakdown voltage
limit on P-channel MosFET's, wich is 200V. This final stage is formed by several
shunted MosFET's, where those of the positive branch are common-drain configured,
and the negative branch are mounted in common-source configuration.
internally compensated in order to obtain gain levels equal or higher than three. The
amplifier's feedback is given by a resistor and a capacitor associated to the operational
amplifier's non inverting input.
Transistors BF587 and BF588 are common-base configured, forming a current supply
structure. This specific transistor type is used because of the higher Vce voltage level
required by this design. They perform simultaneously two functions: they polarize the
MosFET's gate-source junctions, keeping them on the conducting edge, and they
tranfer the OpAmp's output voltage variations referred to signal ground.

FUNCTIONING DESCRIPTION
EP04-99
product:
PAM4/6100
The signal variations normally reflected by Q107 and referred to the positive power
supply, are now needed to be floating variations, and referred to the outputs. This
function is done by Q109-110 (BF588), wich are mounted formig a Wilson-type mirror
current supply. This mirror current supply transfers all of the current variations detected
while descending through Q109's collector, to similar variations on Q110's collector
also downward current. Resistors R167 and R174 are used to balance the current
mirror, in order to avoid the use of transistors with forcibly the same beta value. C138
and C141 suppress their resistance when high frequency signal is processed. Diodes
D126 and D127 avoid the transistors to get saturated, and R171 eliminates the loads
on BF588's bases (Baker Circuit).
The system requires about 12Vdc additional voltage upon the usual Vcc level, this
allows a correct saturation and a symetric clipping at the higher MosFET's.
The correct polarization current value is adjusted by a 4K7 potentiometer connected to
the BF transistor's emitter. This adds an additional current to the current source output
on th BF transistor's loading resistors.
In order to maintain the appropiate stand-by current level against varying temperature
conditions, BD437-type transistors are used. As they have a particular temperaturedepending base-emitter voltage curve, this voltage is used to keep a correct voltage
reference for the current supply. As the temperature rises, the reference voltage level
decreases, the gate-source voltage also decreases and, finally, the bias current also
decreases.

Transistors Q111 and Q112, and their corresponding twins at the lower branch, form
Stand-
a current-buffering circuit wich allows a fast charge and discharge of the power
MosFET's gates.
The Zobel circuit, a resistance-capacitance-inductance formed network associated to
the amplifier's ouput, tries to keep the amplifier's output load impedance constant no
matter wich load value is conected to the output, or wich frequency is processed, in
order to avoid phase shifts on the feedback signal.
To avoid the presence of DC voltage on the output, a diac-triac based system is used,
wich shorts the output to signal ground in case the DC level reaches the diac's
triggering value.To avoidthis tohappen whenprocessing correctsignal (sine
waveform, music...), the diac obtains its reference level from a filtering network formed
by a 100K resistor and a 1mF capacitor.
The protections circuitry overhauls the MosFET's power consumption. Basically, this
circuitry consists of two important sections: MosFET's Id current monitoring, and
MosFET's Vds value detection.
When the MosFET's Id level rises above a certain level, transistor Q119 (controlling
transistor) conducts and decreases the BF transistor's loading resistance, thus reducing
also their gate-source voltage and, finally, lowering the Id current value. This system is
helped by a delayed performance, due to the associated circuitry to Q145 and C174.
This capacitor starts to charge when a current level above the allowed value is
detected, and the protection starts. The greater is the capacitor's charge level, the
higher is also the voltage applied to Q119 controlling transistor's base, increasing its
conduction and, consequently, reducing the gate-source voltage and thus the Id current
value. This system uses a feedback network. The delay used is necessary to avoid
clipping the processed signal's dynamic range, wich should result in the typical clipping
noise. In the negative branch, the protection circuitry is associated to control transistor
Q120.
In case the overcurrent is not ocassional, and persists, after a period of time between
4 and 10 seconds (determined by R142 and C124), the system switches back to
by mode, due to a system-reset. This is done by an optocoupler (IC113) associated to
the negativebranch protection circuitry.When protectionsget activated,IC113
gradually charges C124 untill a 40106-type Schmidt trigger gate switches over . If the
problem persists, this cycle is repeated.
STANDBY CIRCUITRY.
This circuit maintainsthe Output shutdown relay closed for about 10 seconds, and
thus annulates any current through the MosFET's during this period, just untill the
whole system's power supply voltage reaches its stable level. By this system, we avoid
to hear through the loudspeakers any possible annoying noise proceeding from the
system's start-up.
C119=47mF/50V. As this cell charges, its voltage increases untill reaching the
type Schmidt trigger (IC108) switching value; at this point, the relay opens and the
amplifier starts to function normally.
The discharge or reset of capacitor C119=47mF can be done by cutting off the power
supply, or by triggering the Thermal or other protections. During a short period of time,
BC817-type transistor Q102 acts like a switch, shunting two 750 ohm resistors to
C119.
Moreover, the amplifier includes some other additional features, like:
· Volume control by a VCA system.
· An ANTICLIP system.
· A Temperature control system.
The ANTICLIP system. When the amplifier reaches clipping levels, the operational
amplifier looses control on the system's performance and at its output some ±Vcc
voltage peaking pulses may appear, proceeding from its power supply. This peaking
pulses are used to be rectified and sent to an optocoupler (IC111), wich varies the
system's VCA control voltage as a function of those pulse's amplitude, creating a
negative feedback wich should pull back the system into stable functioning area.
The Temperature control system has three main functions:
· Controlling the cooling fan speed, as it is a function of the measured temperature. The
fan's operation voltage range is »7 to 4 Volt.
· Suspending the amplifier's functioning when the temperature exceeds »92ºC
· Reducing the amount of power output, depending on the module's temperature (as it
rises above 85ºC) and on the main power supply's transformer (above 120ºC).
The temperature control system consists on two LM35D-type IC's, wich act like a
thermal probe; one is placed on the amplifier's heat sink, and the other is placed into
the main power supply transformer's core. Moreover, three amplifiers, a comparator
for the thermal probe and a 7805-type IC to feed the cooling fan are used.
The first amplifier (1/4 IC114) acts on the cooling fan speed control. The second
amplifier (1/4 IC114) modifies the VCA gain control, in order to reduce the system's
gain if the temperature rises above 85ºC. The third amplifier (1/4 IC114) modifies the
VCA gain control, in order to reduce the system's gain if the temperature rises above
120ºC. The comparator (1/4 IC114) is responsible for the output shutdown relay
performance, in order to close it as the temperature reaches 92ºC, and thus cutting of
the amplifier's MosFETs bias current. As this happens, the signal output of the whole
unit is cutted off.
- Keep the subsonic filter switch, at the input stage circuitry, set to OFF.
- Be sure that the correct cable types are used.
- Connect the power amplifier mains plug to a 230Vac variac output, and leave it on its 0V position.
- Keep an ammeter nearby (DC 10A range), in order to verify the current consumption adjustments.
VERIFICATION:
- Switch the tested unit's Power main switch to ON, without applying any input signal.
- Remove the protection fuse of the positive power supply, and place instead a 10A DC ranged
ammeter. Keep the module's output signal insight by using an oscilloscope, selecting a 10V/div
vertical scale and 5ms/div time base. Note: In case of doubt, if you only want to feed one channel
while verifying the current consumption, simply do not insert the mains protection fuse in the other
channel.
- Slowly increase the variac’s output until it reaches the unit’s nominal mains voltage, and if an
excessive current consumption is detected (current flow above 800mA), stop the testing procedure
inmediately and try to identify the failure. Once the nominal mains voltage is reached, wait for a
minute and verify that the current consumption adjustments remain correct: 300mA for PAM6100,
190mA for PAM4100. If this values have changed, rectify them. Once adjusted, seal the
potentiometer with fixing lacquer.
Caution! The unit’s power supply will be charged! Before removing the ammeter and
replacing the fuse, it is strongly recommended to completely discharge the unit's power
supply by applying a 1KHz 0dB input signal and connecting 4ΩΩΩΩ load impedances to the
amplifier’s output, and reduce the unit’s mains voltage to 0V by turning down the variac’s
output.
- Repeat this procedure on the other channel.
- Once the adjustments are done, turn on again the unit by switching over its main power switch, and
verify the STANDBY period lasts approximately 10 seconds, the clip and protec indicating LED's
light up, and also the cooling fans run up to their maximum running speed.
- Verify both XLR-type inputs, the STACK-OUT outputs, their correspondent signal present indicator
LED’s and also check the correct functioning of the input signal attenuators, as their actuation range
should be from -∞dB to 0dB.
- Verify the unit’s output power when working at nominal mains voltage (230Vac):
PAM6100 1700W 82,5V on 4Ω
PAM4100 1100W 66,3V on 4Ω
- To verify the ANTICLIP function, increase the input signal level above 0dB and check that the
clipping output signal is smoothened. Check the CLIP indicator LED’s are lit, and, when reducing the
output signal level in 0’5 or 1dB, the CLIP LEDs turn off.
- Verify the unit’s bandwith curve, wich, with a 2KHz 0’5V input signal, should be linear between 20Hz
and 20KHz without inducing any distortion to the output signal. Also check that when applying an
input signal up to 50KHz, the unit’s output level only decreases in 1 or 2 dB, and no visible distortion
is observed.
- Verify the MONO operating mode. Switch over the MONO-STEREO selector to MONO, check that
both channels are achieving the same gain level when not loaded. In order to verify this, apply a
51-0054-0100 EP04-99.doc 1 of 4
Page 67
1KHz 0dB input signal to channel I and, with the volume potentiometer turned up to its maximum,
check with a millivoltmeter that at TP102 a 0dB gain level is obtained. If not, adjust R125. Once
channel I is fixed to 0dB, verify TP102 at channel II and proceed to adjust if gain level is not 0dB.
- Connect a 8Ω load impedance to the speakon-type MONO output, and verify the achieved output
power levels:
3500W 167V for PAM6100
2200W 132,6V for PAM4100
Only channel I's input potentiometer should be active. Verify that the amplifier reaches its clipping
state without troubles. Return the unit to its STEREO operating mode.
- Connect a load impedance formed by a 4Ω resistor shunted to a 2µ2F capacitor, and apply a 1KHz
square waveform input signal. Using an oscilloscope, observe the output signal, and increase the
input signal level until the displayed signal starts clipping. At the flat level areas of the squared
waveform, only two or three ringings should be detected.
- Verify the SUBSONIC FILTER's performance. Check the amplifier’s output level at 40Hz, 30Hz and
20Hz, depending on the selected switch position, is reduced in 3 dB when comparing with the
measured level without subsonic filtering. Leave the selection switch on the 20Hz position.
- Verify the THERMAL protection circuitry. Short the LM35D thermal probe pins 1 and 2, and verify
that the relay releases and closes, while the THERMAL and PROTEC LEDs indicators light up, as
the output signal is cutted off and the cooling fan increases its speed untill it reaches maximum
airflow.
- Repeat this procedure on the other module.
PROTECTIONS
- Adjust the signal generator to deliver a 1KHz 0'8Vrms signal, and leave it ON.
- Turn down the power stage volume potentiometer to its minimum.
- Connect a 0'5Ω load impedance.
- Connect the oscilloscope test probes parallel to the load impedance. Select a 5V/div vertical scale,
and a 0'2ms/div time base.
- Turn up quickly the volume potentiometer. Depending on wich branch is working, the positive or
negative half of the signal cycle is clipped. Verify that no ringings appear when the protection is
triggered.
- The output signal should be somehow similar to the picture shown in the figure (from 15Vpp to
20Vpp). There are two protection circuitries, one on the positive and another on the negative
branches of the unit. In case one of this protections does not actuate properly, the output signal will
appear completely assymetric. The level of the half-cycle wich is not being protected will not be
limited, thus allowing to find out wich branch is failing. It could also happen that none of the
protections are triggered, this can be detected as the measured signal levels delivered to the load
impedance are not being compressed. In case this happens, inmediately stop the testing procedure.
This may occur when the unit is receiving too low mains voltage (at least 240V, 250V
recommended), or if the signal level is increased too slowly through the potentiometer.
- After a period between 5 and 10 seconds is elapsed since the protection circuitry has triggered, the
module should switch over into PROTECT operating mode. This is, the relay closes, the PROTECT
indicator LED lights up, output signal is cutted off, and the 10 seconds lasting STANDBY cycle is
started.
- Wait untill the STANDBY cycle ends, and allow the unit to repeat the process.
- Turn off the signal generator, output level set to minimum.

DC OUT
- In order to run this test, do not connect any load impedance.
- Adjust the signal generator to deliver a signal with a frequency below 5Hz, and select the 3V scale
output level.
- Connect the oscilloscope to the unit's output, 5V/div vertical scale, 20ms/div time base. Use a 10x
attenuating test probe.
- Turn on the signal generator. Increase its output level untill the thyristor starts actuating, and the
observed signal becomes the typical sawed sine wave. Use the oscilloscope's memory bank in order
to observe carefully this fact.

QUALITY CONTROL
All mechanical parts should be visually revised, in order to detect scratches on the unit's painting; all
screws should be on their place,correctly tight and unmarked. Check out the unit's general presentation.
BURNING TEST
Leave the tested units connected to the burning verifyer, while performing their burning test. If testing
PAM 6100, do not connect more than 4 power stages to each column. If testing PAM 4100, a maximum
of 7 units can be connected simultaneously to each column.
VERIFICATION USING MUSIC
Verify the unit's sound quality, wich should be distortion- and noise-free. Once the unit is turned in and
its STANDBY cycle time has elapsed, the output relays release, but no annoying noise is heard through
the loudspeakers. Also check that all potentiometers can run smoothly their whole sweep, without noise
and crisperings. At their minimum position, check that output signal is completely cutted off. To ensure
that all electrical junctions are well-fixed, hit the tested unit against your working table, obviously without
damaging its outer presentation. Verify all in- and outputs. Short the output terminals while carrying
amplified signal, wait approximately 5 or 10 seconds, after wich the unit should perform a general reset.
Verify the PROTEC indicating LED lights up, the output signal is cutted off, and the STANDBY cycle is
correctly done. Once the short-circuit is removed, the unit recovers normal functioning.
