• Input level : 0dBu (0.775V) 66kΩ 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 matching 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.
• 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).
