    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...).
  • Page 5 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.
  • Page 6 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.

  • Page 7: Protection Circuit

    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.
  • Page 8 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.
  • Page 11 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...
  • Page 12 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.

  • Page 14: Temperature Detector

    TEMPERATURE DETECTOR This circuit is calculated to operate over the output relay opening it if any of both modules' temperature excedes 90 E C, 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 "...
  • Page 15 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.

  • Page 16: Clip Circuit

    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.
  • Page 17 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.
  • Page 18 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.
  • Page 20 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.

  • Page 75: Frequency Response

    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.
  • Page 76 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.
