Power Amplifiers 100V - 4 channels - DC 24V

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
