Description

CHARACTERISTICS

Variable speed automatic fan (thermal sensor)
100V outputs for HP line
Class-D: the amplifier offers a small size with a light weight
Designed to run on AC mains or 24V DC battery
Optional fault monitoring module (FD 200) for monitoring amplifiers and loudspeaker lines (short-circuit and open-circuit failures)
A level reset relay contact on the output terminal block allows, in case of emergency, the broadcasting of calls on 3 or 4-wire lines that need a 24VDC power supply.
RMS output powers: 500 W x 2 and 1000 W
The optional fault monitoring module enables the switchover to a standby amplifier or loudspeaker line in the event of an amplifier or loudspeaker line failure if the FS-3381 switching system is connected in between.
Total protection for reliability
Overload protection circuit and short-circuit limiter
Overvoltage protection circuit
Input level: 0 dBu°(0.775V) 60 KΩ balanced (2 inputs)
Power-on noise reduction circuit
Audio Priority input terminal and remote control terminal Priority
200 Hz high-pass filter to improve sound quality
Signal inputs on screw terminal block for easy installation
