Rated outputs: 120W/240W x 4 (RMS). • Input level:0dBu(0.775V)60kΩ balanced. (1 Program and 1 Priority Inputs) • Full protection for product reliability. - Overload and speaker line short limiter circuit. - Over current limiter circuit. • Automatic variable speed FAN by temperature of heatsink. • 400Hz filter to improve clearance of sound quality for matching of resonant sound of inner side. • 25V, 35V, 50V, 70V and 100V Outputs for macthing of speaker impedance(optional). • Screw terminals for signal input to make an easy installation. • Soft start circuit for AC power on. • Designed for operation either AC mains or 24VDC. • +24V DC out to external accessories (max.500mA). • AC power remote control(Stand-by LED) • Optional FAULT DETECTOR MODULE(FD-20) can easily be fitted for monitoring of amplifiers and loudspeaker line(short, open) failures. Priority Audio input terminal and Priority control terminal.
ADDED FUNCTION OF DPT SERIES • Fault monitoring of fan fault, DC fuse fault and AC fuse fault. • PGM audio muting level controller when priority control signal input. • A priority relay contact of the output terminal board allows emergency paging to be distributed through 3-wire or 4-wire system wiring that requires the DC power supply. • Optional fault detector module makes detection of speaker line fault or amplifier fault and change from fault amplifier into Stand-by amplifier by JFS-381 (Fault stand- by AMP switcher).
