MODULE CIRCUIT 11.0504B OPERATION - DESCRIPTION

The control element is the operational NE5534. This is a very low noise operational, especially designed for very high quality applications in professional audio equipment, control equipment and telephony channel amplifiers.

The operational is internally compensated for a gain equal to or higher than three. Frequency response can be optimized with an external compensation capacity, for several applications (unity gain amplifier, capacitive load, slew-rate, low overshoot, etc...).

Characteristics:

Small-signal bandwidth: 10Mhz

Output drive capability: 600 Ω 10V(rms) at Vs="18V

Input noise voltage: 4nV/

DC voltage gain: 100000

AC voltage gain: 6000 at 10KHz

Power bandwidth: 200KHz

Slew-rate: 13V/µs

Supply voltage range: "3 to "20V

POWER SUPPLY

The BF871 and BF872 transistors are mounted in a common base configuration, in a current source structure. The current sources have a double function: polarizing the gate-source links in the MOSFETs to the limit of the conduction and moving the voltage variations at the operational output which are refered to ground to voltage variations refered to high voltage power supply. The polarization point is calculated so the voltage dropout in

Rc (R112+R111) is the limit voltage of conduction of the MOSFETs (.2 to

3V), enough to carry the bias current. If we modulate in AC the base-emitter voltage, the Ic and VRc will vary proportionally. In our configuration, as the reference voltage Vref is constant (it is a part of the operational power supply), we add the operational output voltage to the transistors emitter through Re (R107-R108).

The Rc value fixes the source output impedance. We do not recommend to raise it higher than 1K Ω because of frequency response and slew rate reasons. This voltage circuit's gain is, as usual in a common base configuration with Rc/Re emitter resistor, 0.45.

BIAS CURRENT ADJUST

The bias current adjust is performed through the variable resistor connected between the emitters of the current sources R110 (5K Ω ). It delivers a supplementary current (it does not go through the operational) which simultaneously increases the voltage which falls in the Rc load resistors.

This is the easiest way of acting with just one adjust over both branches at the same time. In order to adjust the bias current the adjustable resistor must be varied until a current of about 80mA circulates through each MOSFET. So, for instance, for a PAM1400 in which there are six MOSFETs it will be 80 x 6 = 480mA. The bias current depends on the

MOSFETs temperature and the stabilizing circuit transistors temperature.

TEMPERATURE STABILIZING CIRCUIT

Temperature affects MOSFETs conduction in two different ways: first, the conduction threshold voltage has a negative temperature coefficient; second, the drain-source conduction resistance increases with temperature. Depending on which of the two things is predominating the temperature coefficient of the drain can be positive or negative. In our case, in which the gate-source voltage in the

MOSFETs is very low when they conduct, the temperature coefficient of drain current -which is positive- is predominating.

To avoid thermal runaway in the polarizing current we must decrease the gate-source voltage as the MOSFETs get hot.

Temperature stabilization is performed by modifying the reference voltage of both sources. If the temperature increases the Vref must decrease so that Ic and VRc decrease and, as a consequence, the gate-source voltage also decreases.

The circuit used is shown in figure 3. The base-emitter Vbe temperature/voltage feature is used to obtain the final result we need.

The main idea is adequately choosing R1 and R2 to obtain the right temperature coefficient.

SYMMETRY ADJUST

The threshold voltage varies much, even between

MOSFETs of the same kind. When connecting them in parallel we must be careful that they all have the same conduction current if we want equal currents circulating in all of them. If the conduction voltage of P an N channels

MOSFETs is not the same they will conduct different currents, even when we apply identical gate-source voltages.

As the bias current of the N MOSFETs must be identical to the one of the P MOSFETs the feedback will correct the continuous voltage at the operational output to polarize the

MOSFETs with different voltages until both conduct equal currents.

If the operational output is not 0 V its capacity to give voltage and current is not the same in both senses. To avoid this we must put a symmetry adjust. It is just an adjust which allows to vary the collector resistance of one of the current sources (R111).

The symmetry adjust does not correct the asymmetrical clipping saturation of the power amplifier with real load. This happens because the conduction resistors

(Ron) of the MOSFETs N and P are not equal. Channel P has a higher Ron than channel N. This characteristic depends on the MOSFET's physical construction.

POWER MOSFETs

The MOSFETs used are IRFP9240 (P) and IRFP240 (N). They are assembled in a common source configuration so they can be completely saturated.

This kind of configuration has two drawbacks compared to a common drain one: less stability (because of the configuration gain itself) and high output impedance in open loop.

The source resistances (0.22

Ω ) are needed for the MOSFETs to work in parallel. E.g.: Two MOSFETs excited by the same Vgs voltage (gate-source voltage) of 5V. If they have different transconductance curves (Id function Vgs) they will conduct different drain currents; let's say 1A and 3A. The second one will dissipate more power and will get hotter.

The use of source resistances tends to match the current that each of the MOSFETs connected in parallel is conducting.

This resistance performs a negative feedback on the gate, lowering down the Vgs, relating to the drain current; like this:

Vgs = Vgg - Id*Rs

The higher the Id, the lower the Vgs voltage. The gate is protected by a zener, preventing a possible overload during an unexpected change from overload to real clipping.

Given the high input impedance and the broad frequency response of the MOSFETs there is a high risk of self-oscillations if all gates are excited connected to the same node. Intercalating serial resistances and ferrite beads at the gate this possibility is minimized, because the Q of the LC network made by the inductances and gate-source capacity is reduced.

PROTECTION CIRCUIT

The protection circuit monitors the dissipated power at the MOSFETs stage. It has two basic parts:

MOSFET Id current detection.

MOSFET Vds voltage detection.

The goal is limiting the MOSFET so it works inside an area close to the SOA, as indicated in the figure. We chose channel N because, due to construction reasons, its SOA is lower.

ZONE A. This zone is for very low loads, around 0 Ω . As the load voltage is very low, the voltage held by the

MOSFET will always be high. The protections should be activated with very low current.

Fast protections and some of the slow ones are working in this zone. The circuit that configures the fast ones is made of: D120,

D121, D123, R174, R175, R176, R177, R178, R179, C127, Q122 and Q123 for the N channel. There is also an equivalent circuit in the

P channel. These start working when there is a sudden current variation because of a shortcircuit or a transitory. The reaction time

-from the exact moment when these things occur to when the current stops circulating through the MOSFETs- is about 80µs.

C B A

Vds

Please note that in order for the protection to be activated

Q122 and Q123 must conduct simultaneously, through which R174 is linked to negative power supply, being C127(1µF) loaded very quickly through this resistance, activating the LED of the opto-coupler, sending a pulse to the protection circuit, which will open the corresponding channel's relay, being this way the output from the power amplifier disconnected from the load (0 Ω ), in this case. Q122, together with the zeners and the base polarization resistances, configure the voltage detector (this group is in parallel with the Vds voltage of the

N MOSFET).

The time constant is given by C127, R174 and R179 and the load circuit made by the LED diode of the IC104 (opto-coupler).

Q123, together with the resistances which make the base divider, configure the current detector (this divider takes its voltage from one of the source resistances of a N MOSFET, which is proportional to the current circulating through itself).

The threshold separating zone A from zone B is determinated by the D125 zener. When this zener stops working and there is no current circulating through it because the Vds voltage is lower (let's remember this circuit is also in parallel with this voltage) or, what is the same, the load voltage grows because it is not 0O anymore and has a given value, like 0.5

Ω to 1 Ω , and the help given by D126 stops so more current will be needed for the shot. We have climbed the first stair of the stairway of the SOA graphic.

When the zeners D124 and D118 stop working because the load voltage goes on growing (values higher than

1 Ω ) or -what is the same- the Vds decreases, the Q125 transistor does not receive current anymore in its base and so it is shorted, allowing Q124 to enter conduction. This way R172 stays in parallel with the base-emitter of Q121, making up a voltage divider with R173. This divider will climb another stair of the stairway and enter the ZONE C.

The link between the module's protection circuit and the relays' control circuit is made through IC103 and

IC104 which are, as mentioned earlier, opto-couplers, just to insulate the existing high voltages at the power amplifying module, "90V in the case of the PAM1400, and the power supply voltage of the existing logic circuits in the relays' control card.

Once the pulse generated by the protections is detected, the control circuitry resident in the protection card, appart from opening the corresponding relay, returns the signal A.O. SUPPLY CONTROL to the module, which cuts by means of Q119, Q120 and IC102 the operational's power supply.

This is the way to insure a fast and safe cut of the Id current in the MOSFETs (around 80µs time), because they stop receiving their respective reference voltages and, consequently, their Vgs polarization voltages so they are cut. The circuit is shown in figure 9 and its operation is very simple.

When the A.O. SUPPLY CONTROL (+10V) signal appears, the Q119 transistor starts conducting, shortcircuiting to ground the positive power supply of the operational. On the other hand, the signal is also applied to the IC102's LED (opto TIL112 (4N35)), which puts its internal transistor and Q120 into conduction, connecting the negative power supply of the operational to ground.

ZOBEL NETWORK

This circuit tries to get a constant load impedance for the power module, in spite of the amplifier's load and frequency, to avoid phase shifting of the feedback signal.

The values have been experimentally calculated through a study with square signal by trying to minimize the power amplifier's ringing with very capacitive loads (2,2µF//4 Ω ).

The Zobel Network eliminates possible oscillations of the MOSFETs between 5MHz and 10MHz, too. This is why it must be physically placed at the module's output, avoiding long wiring. Great care must be taken for the signal not to be too shifted at the output, because the feedback could turn negative.

FEEDBACK

The whole amplifier is compensated with just one capacity, which places the amplifier's general pole at:

Fp = -------------- = 140KHz

2* π *Rf*Cf

Rf = R106 Cf = C109-C110

PROTECTION CIRCUIT 11.0411 OPERATION - DESCRIPTION

The circuit is configured by:

- A POWER SUPPLY.

- A THERMAL PROBE DC AMPLIFIER.

- A TEMPERATURE DETECTOR.

- A DC OUT DETECTOR PER CHANNEL.

- A CLIP CIRCUIT PER CHANNEL.

- A RESET (TURN OFF/TURN ON) CIRCUIT.

- A BINARY COUNTER PER CHANNEL.

- TWO MONOSTABLE CIRCUITS PER CHANNEL.

The circuit power supply is performed through various sources: +V, module's power supply. This voltage feeds the relays circuit, manual reset circuit and part of the clip circuit. Alternate voltage from a transformer's secondary (manual reset circuit).

There is also a stabilized 10V power supply which feeds the card's circuitry, made of IC301 (7805) plus the zener D302 (Z4.7) 4.7+5 . 10V. We will also need a regulated power supply to get 14Vmax at 0.7A, which can be obtained with IC302 (7805) plus an auxiliary circuitry that will be analysed below.

The cooling fan speed is automatically regulated in relation to the power module's temperature, which is read by a thermal probe (LM35D), jointly linked to the heat sink.

This high sensitivity thermal probe gives variations of 10mV for every EC. This voltage is picked up and amplified by the IC305 (LM358). Of course, there is a probe for each L and R heatsink. The output of both amplifiers is linked through two diodes D304 and D305, making an O gate, whose cathodes go to the regulator, applying the DC of any of them to the regulator. This provides a variable voltage at its output which oscillates from a minimum of approximately 7V for a temperature of 20EC (cold heatsink) to a maximum of 14V for temperatures of 76EC or higher.

The gain of the amplifiers has been calculated for this temperatures window. The maximum voltage allowed by the heatsink in order to work properly is 14V. This maximum is given by the zener D305 (Z9.1/1); as the regulator is a

7805 the voltage will be -as maximum- 9.1+5 = 14.1V. When the zener is not working (not enough voltage) the voltage on the fan will be the output amplifiers', less 0.6V (diodes fall), plus the 5V of the IC302.

TEMPERATURE DETECTOR

This circuit is calculated to operate over the output relay opening it if any of both modules' temperature excedes 90EC, approximately. It is made with a comparator per channel (L-R), resident in the same IC306. Both share a reference voltage provided by D306 (TL431A), which gives excellent stability at that voltage "1%. These comparators reveive, like the DC amplifiers, the signal from their probes, comparing them with the Vref. Once this voltage is surpassed by any of both probes, the output of the corresponding comparator is balanced to the power supply (+10V), acting through D307, R318, D308 and R319 over the respective bases of transistors Q301 y Q307, which makes the corresponding relay open. This output is also connected to the THERMAL LEDs, which light up as the relays are open.

Note that each time the relay is open through any of the variables which act upon it the PROTECT LED must light up. The circuit acting over this LED is made of R327, R328, R329, R4, R5 and Q303. When Q302 stops conducting (open relay), Q303 receives its base current through R327, R326, R6 and the relay's coil, putting this transistor into saturation. This way the LED is linked to the power supply (+V) by means of the group of resistances

R328, R329, R4 and R5.

DC OUT CIRCUIT

The circuit shown in the figure corresponds to the DC OUT of channel L. The goal of this circuit is protecting the loudspeakers when, because of a module fail, there is some DC appearing at the output. The voltages indicated in the figure correspond to rest state and they are given by the dividers made of R320-R322 and R332-R323.

The resistances R323-R322 are linked by their extreme to the leg 7(Q) of the monostable IC310 (4538), which has +10V at rest state. On the other hand R320-R321 are linked by their extreme to the L output, which, in these conditions, has 0V respect to ground. If we apply Ohm's Law to these dividers we will obtain the above mentioned voltages.

Let's remember briefly the function of a NOR gate like the HEF4001B.

A B C

1 0 0

1 1 0

Let's suppose there is a continuous voltage appearing at the module output, because of any malfunction.

This makes the voltage dividers lose balance, no matter if the above mentioned voltage is positive or negative, the gate goes to 0V, the base Q302 loses the current stream and, as a consequence, the relay K301 opens. The aim of the zeners D309 and D310 is protecting the gates, avoiding the voltage in them to be higher than 8.2V when the voltage is positive and lower than -0.6V when it is negative; as you can see, the zener plays the role of a diode.

CLIP CIRCUIT

The other half of IC307(4001) is used in the clip circuit. Given that we have two gates more and we just need one for our purposes we will connect them in parallel for a higher output current and a more effective LED lighting up.

The clip threshold or point where we want the LED to light up is determined by the zener D313. In our case it is between 0.5 and 1dB or, what is the same, when the output signal level over the load reaches a value close to that of the power supply (+V), exactly Vout = V - 5.6, moment in which Q304 loses the base-emitter voltage stopping conduction; this makes the zener D312 voltage disappear (0V) and the output from IC307 go to "1" logic (+10V), making the LED light up.

GENERAL RESET CIRCUIT (TURN OFF/TURN ON)

TURN OFF RESET. This circuit starts working when the AC current from the transformer secondary disappears or, what is the same, when we turn the power amplifier off by pushing the power off switch, actually disconnecting it from mains.

Circuit operation: The AC signal present at the anode D321 is rectified by this, attenuated and filtered by R13,

R348, R347 and C322, apllying it to the base of Q306, which is conducting into saturation and, as a consequence,

Q305 is cut. When this signal disappears Q306 is cut and then Q305 has its base feeded through R345, R346 and

R14 from the +V power supply, which has begun to lose voltage -because we have just cut the mains- but, because of the high capacity value of the filter condensers, there is enough time to saturate Q305, which puts the resistances R15 and R344 (50 Ω ) in parallel with the power supply (+10V) of the logic circuitry, completely discharging the capacities of the circuit, leaving it ready for a new reset pulse -the connection one-, what warranties the new turn-on, even with very short time intervals (.1s) between turn-off and connection pulses.

CONNECTION RESET

This is made of C315, R336 and D314. It is the classical reset circuit, used in lots of applications.

In the exact connection moment the condenser C315 is not charged, with a high amount of current circulating through it, or a high voltage in R336. This current decreases as the condenser is charging until it disappears. At the same time, the voltage -in the extremes- of the resistance goes from maximal, in the beginning, to 0V. This way we get a pulse whose duration depends on the time constant RC. The aim of the diode D314 is a fast discharging of C315 during disconnection.

BINARY COUNTER HEF4520

This is a 4-bit double binary counter. Configured in a way in which when there is the binary code equivalent to decimal number 5 at its output -so this is 1 0 0- it is blocked in this position, until it receives a new MR reset pulse. The blocking action is performed by the NAND gate between legs Q2 and CP1. At this state Q2 becomes "H" one logical, the NAND changes its state putting the leg CP1 to "L" zero logical and -as you can see in the table of functions- the mode can not change in this conditions.

CPO CP1 MR MODE

L counter advance counter advance

L no change no change no change no change

X X H Q0 to Q3=low

The general turn-on reset initializes the counter. Every time it receives a pulse from the module opto-couplers because of a protections shot it is counted. If during an interval of approximately 5 minutes it does not receive any other pulse, the counter will go back to the original zero state, because it receives a new MR reset pulse from the monostable IC311, whose time constant is approximately 5 minutes (R342,C319). This monostable begins counting from the very first pulse received by the counter, because both are linked to the PROTECT SIGNAL from the module and, consequently, activated at the same time.

If during this time interval (about 5 minutes) a minimum of 5 successive pulses are received, these will make the counter block at that position. This translates into a logical "1" at the Q2 leg of the counter, a "0" at the NAND

(IC308) output; this zero makes a "1" at the output of the next NAND, giving a result of "0" at the collector of Q301, so

Q302 is not conducting and the relay K301 remains open. It will stay this way until the reset from the monostable happens or there is a manual mains disconnection by pushing the power off button.

The reset circuit associated with the monostable is made of C320, D320, R339 and D318 (above we have always been refering to channel L). By means of diodes D317 and D318 we build an "O" gate, with which we apply any of the above mentioned reset pulses to the counter.

STANDBY MONOSTABLE

The only thing left is the function of the monostable made of IC310 (4538).

Like the counter and the monostable IC311 (4538), this circuit is connected to the PROTECT SIGNAL, too. Its output is "1" in rest state and becomes "0" during an approximate time of 1.3 seconds, which is given by the constant

RC of the circuit R341 C316.

This leads to two situations: First, putting a "0" in one of the legs of the NAND (IC308) generates the immediate opening the relay, as we have seen before. On the other hand the voltage divider of the DC OUT circuit is put off balance. The monostable time is calculated to be long enough to unload the capacities of C312 and C313. This way we get a DC OUT circuit initialization as we had done a manual reset (disconnection from mains), causing the tipical turn-on STANDBY time for each of the disconnections of the relays because of the protections shooting. Let's take into account that the system is locked after the fifth disconnection.

PRINTED CIRCUIT

PROFESSIONAL PAM SERIES - TESTING RULES

PRELIMINARY

GROUND LINK Testing.

- Verify that when the switch is at the ON position there is continuity between the chassis ground and the speakers ground terminal and that the opposite happens at the OFF position. Leave it at ON.

- Put the power amplifier in stereo mode.

- We will need a 1800VA variac for our test purposes.

- Take off one of the fuses of the module in which the testing is being made and connect an ammeter (10A DC scale) in its place.

- Put the oscilloscope probe between TP-GND.

SET UP

- Unplug the fuses of the module that we are NOT setting up.

- Connect the power amplifier mains cable to the output of the variac. Set the variac output at 0V.

- Switch the power amplifier on with no load or signal. Turn the variac up progressively step by step until 220V.

While mains voltage is growing up make sure the module's current does never exceed 0.8A. Once the circuit is stable make sure the current is 480mA/400mA/320mA/240mA respectively for PAM1400/ PAM1000/ PAM600/

PAM300 and the symmetry (measured up with the oscilloscope probe) is #50mV. If your figures do not match these numbers adjust CURRENT (5K) and SYMMETRY (470 Ω ) until you get the above mentioned numbers.

- Test the operational amplifier power supply ("18V) "1V.

- Put the fuse back in its place into the module (with the power amplifier turned off) and repeat the same procedure for the other channel.

CROSS DISTORTION

By using a signal generator introduce a level of 100mV RMS at 1kHz and make sure there is no cross distortion at the output (attenuators at 0dB position).

MOSFETS CONDUCTION

By using a signal generator introduce a level of 0.5V at 1kHz and load the amplifier with 4 Ω .Check that all

MOSFETs are conducting approximately the same current level (measure this current with the oscilloscope probe by palcing it on the 0,22 Ω source resistances).The maximum conduction difference between MOSFETs should be 100mV. When making this test be sure the oscilloscope ground is not connected to any other place of the circuit when making the reading; just to the 0,22 Ω resistance.If you do not follow this rule you could produce a shortcircuit between two points of the circuit and therefore a very important damage.

POWER

- Verify the amplifier's power at 8 and 4 Ω .

- Maintain the mains voltage at 220V by means of the variac.

- Check that your own figures match the following at close-to-clip point:

Vin.1VRMS/Vo 4 Ω

Vin.1VRMS/Vo 8 Ω

PAM1400

49.0Vrms

56.0Vrms

PAM1000

45.1Vrms

49.7Vrms

PAM600

34.5Vrms

39.7Vrms

PAM300

26Vrms

30Vrms

FREQUENCY RESPONSE

0.5V input signal.

Verify frequency response at 20Hz/2kHz/20kHz. We must get the same signal output for the actual load at any of the frequencies. Set the frequency at 50kHz; the output level should not decrease more than 1 or 2 dB and there should not be any noticeable distortion.

CLIPPING AT 1kHz

Introduce such a signal that the amplifier is just about to clip. Measure the voltage up at the output (with the actual load) and check that when the voltage decreases between 0.5 and 1 dB the clipping LEDs light down.

Check each LED corresponds to its fader.

DC OUT

For this test you must disconnect the load from the amplifier.

Introduce a 1V signal at #5Hz with the generator. Turn the output of the generator up until the protection relays open and close.

MONO-STEREO

Make this test with a load of 8 Ω connected between left and right channels' terminals.

Set the MONO-STEREO switch in MONO. Verify that the fader of channel 1 is operating while channel 2 is NOT operating. Verify that the MONO LED is lighten up. Check the signal cut over the load is clean. Set the amplifier back to STEREO mode.

PROTECTIONS

Disconnect the amplifier from the load and introduce with the signal generator a level of approximately

100mV RMS at 1KHz. Leave the attenuators at 0dB and shortcircuit the left channel output (just for a while) checking the PROTECT LED is lighting up and the relay opens the circuit (you can check this by placinf an oscilloscope probe at the amplifier's output and watching the signal disappear during the STAND BY time in which the protection circuit is working).Repeat the same process for the right channel.

Set the amplifier in MONO mode in the same way as previously. Shortcircuit both channel output terminals (L and R) (just for a while).Any of both channels must go into protect mode, lighting the corresponding

LED and making the relay open the circuit.

PROFESSIONAL PAM SERIES - QUALITY CONTROL

We will use a mixer with balanced output -if possible- and a nominal output level of 1V as the signal source for test purposes.

Connect the mixer outputs to the power amplifier inputs. Plug the power amplifier to mains (make sure its specified voltage matches that of mains) and make sure that PROTECT, ON and SIGNAL PRESENT LEDs all light up when you turn on the amplifier by pushing the ON button. Turn up the mixer output level untill the CLIP

LEDs light up on the power amplifier. Turn down the mixer output and connect the loudspeakers.

Make an exhaustive test of:

- Sound quality (no distorsions or noises)

- Faders action (fader travel, signal cut at their low end, no scratching or clicking noises and correct stereo channel for each one).

- Cooling fan operation.

- While the power amplifier is working shake it or throw it a table to make sure the output sound goes on playing correctly.

- Shortcircuit the power amplifier output and make sure the corresponding channel's PROTECT LED lights up, the relay opens and the output signal is cut for a short period of time (STAND BY) and returned back into normal operation. Repeat the same procedure four times more and then the STAND BY time should be about 5 minutes.

Repeat the same steps for the other channel.
