Bogen Communications TPU250

The Bogen TPU250 is a wall-mounted telephone paging amplifier rated at 250 watts. This amplifier permits paging from telephone and/or microphone. Music input through an RCA jack or screw terminals. Voice-activated, variable level, music mute with fade back after page. This amp also includes a night ringer which sends an electronic ringing tone signal through all speakers, alerting personnel of incoming calls during non-business hours. Jacks are also provided to bridge two TPU amplifiers to double the number of inputs and outputs.
