Bogen TPU250 250-Watt Telephone Paging Amplifier

Specifically Designed for telephone paging, the Bogen TPU series of telephone amplifiers offers a choice of rated power output from 15 to 250 watts. Input terminals are provided for a 600 Ohm balanced telephone line and background music source (FMR or TP30D), as well as a balanced low-impedance microphone in the TPU-100, TPU-60 and the TPU-35. The built in night ringer (except TPU-15A) sounds a tone through the paging system speakers when triggered by the external contact closure. Voice-activated circuity automatically mutes or fades music when paging.

Bogen models TPU35B, TPU60B, TPU100B, and TPU250 are wall-mounted telephone paging amplifiers rated at 35, 60, 100, and 250 watts, respectively. The TPU250 can also be rack-mounted. This group of TPU amplifiers 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. All the TPU amps in this group include 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.
