Bogen TPU100B 100-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. Key Features: Mfr. Part #: TPU100B Inputs for 600-ohm balanced telephone line, LO-Z balanced microphone, and background music Integral automatic level control circuit for controlling pages made by persons with varying voice levels and paging techniques Page from telephone and/or microphone Signal-activated paging channel automatically mutes background music Adjustable background music muting level during a page Music gradually returns to its normal level after a page Aphex Aural Exciter increases intelligibility, improves perceived loudness (with no increase in power), and reduces listener fatigue Seperate controls for page volume, music volume, night ringer, music mute and Aphex Aural Exciter Bass and treble controls Built-in night ringer activated by contact closure or by 90V ring signal Balanced or unbalanced 16-ohm, 25V, 25VCT, and 70V outputs VOX sensitivity level control eliminates transmission of background noise when paging from a telephone Thermal and electronic overload protection Jacks provided for bridging additional TPU amplifiers Brackets are attached for easy wall mounting Peak level indicator lights when amplifier is driven into clipping 120V AC, 60Hz power source UL and CSA listed Condition: Refurbished
