Series of 4-channel Public Address power amplifiers with 25V / 50V / 100V line outputs. Delayed start, symmetrical line and priority input, operation with emergency power supply.

CHARACTERISTICS

  • Variable speed automatic fan (thermal sensor)
  • 25V, 35V, 50V and 100V outputs for loudspeaker line
  • Designed to run on AC mains or 24V DC battery
  • Optional fault monitoring module (FD-200) for monitoring amplifiers and speaker 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.
  • Input level: 0 dBu°(0.775V) 60 KΩ balanced (4 Program inputs, 4 Priority inputs)
  • 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.
  • RMS output powers: 4 x 120W and 4 x 240W
  • Total protection for reliability :
  • Overload protection circuit and short circuit limiter
  • Overvoltage protection circuit
  • 24V DC output for external devices (max. 500mA)
  • Terminal board for power supply remote control (stand-by led)
  • Signal inputs on screw terminal block for easy installation
  • Priority remote control via Talkover on PGM input
  • Audio Priority input terminal and remote control terminal Priority
  • Power-on noise reduction circuit
  • 200 Hz high-pass filter to improve sound quality
  • DP SERIES FUNCTION OPTIONS

Fault monitoring fan, AC fuse and DC fuse
