תיאור

 Automatic variable speed fan control by Thermal sensor
50V, 70V, 100V Outputs for macthing of speaker
impedance (optional).
● Designed for operation either AC mains or 24VDC.
● Optional FAULT DETECTOR MODULE (FD-200)
makes monitoring of amplifiers and loudspeaker line
(short, open) failures.
● An override relay contact on the output terminal board
allows emergency paging to be distributed though 3-wire
or 4-wire system wiring that requires the DC power supply.
● Input level : 0dBu(0.775V)66kohm balanced.
● Optional fault detector module makes detection of speaker
line fault or amplifier fault and change from fault amplifier
into Stand-by amplifier by FS-3381(Fault stand-by switcher).
● Rated outputs : 600W/720W/1000W(RMS)
● Full protection for product reliability.
– Overload and speaker line short limiter circuit.
– Over current limiter circuit.
● +24V DC out to external accessories (max 500mA).
● AC power remote control(Stand-by LED)
● Screw terminals for signal input to make an easy installation
● PGM audio muting level controller when priority control
signal input.
● Priority Audio input terminal and priority control terminal.
● Inrush circuit protection for AC power on.
● 400Hz filter to improve sound quality.
OPTIONAL FAULT MONITORING MODULE(FM-300)
● Fault monitoring of fan fault, DC fuse fault and AC fuse fault.
● P.C.L Protection adoption
