General characteristics

- Electronic protection against short-circuits in output.

- Power supply suspend.

- Excess temperature (110 C in the power radiator) detector. In the event of overheating caused by a
ventilation obstruction, a safety device will be triggered. When temperature conditions revert to
normal this devise switches off automatically.

- Digital keypad for microphone volume, auxiliary volume, treble and bass.

- Control device for attenuator with maximum level restoration (three wires) incorporated.

- Input 1: balanced microphone, phantom power supply with remote control input (TM1).

- Input 2: auxiliary with remote control input (TM2).

- Signal input/output connection for audio processors (EG-31, etc.)

- Signal output for other amplifiers, with remote-controlled device for attenuators.

- On/off

- Modulation

- Luminous digital display

- 230 VAC at 50/60 Hz

. Antilarsen module.

. Handle / bracket for mounting on 19” rack

. Signal lead

. EG-31 insertion cable.

The

amplifier has a plug-in connection jumper which allows the user to change the

sensitivity of the auxiliary input from 770 mV to 250 mV (see graphic).
