  • Page 3 GENERAL DESCRIPTION The S series is a hi power amplifier composed by 2 or 4 channel class H technology fed by a switching power supply. It has twin male-female XLR back pannel input connectors per channel with the posibility to work in ste- reo, parallel or bridge modes.
  • Page 4 GENERAL DESCRIPTION Power supply description The amplifier has a switching power supply fully independent and self commanded and protected, to feed the DC voltage to the audio power section. The mains voltage passes through an interference filter to filter out both the switching noise to go out and the mains interference to come in.

  • Page 6 You can measure then the voltages at the output connector, they will be lower than expected because the voltage drops at the bulbs. The voltages are the following: S 1500: ±49V / ±81V S 2000: ±49V / ±98V S 3000: ±65V / ±114V...
  • Page 7 QUICK REPAIR PROCEDURE POWER AUDIO SECTION: When the audio section breaks, the usual consequences are that some final transistor or/and driver transistor gets shortcircuited. It is possible to get also some class h conmutation mosfet transistor or diode shortcircuited. To check it you have to use a multimeter in diode mode or resistance measure. If the final transistors are OK you can measure around 10ohms between the base and the emitter and very high resistance between collector and emitter.
