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.

Features

• 35, 60, 100, and 250-watt models
• Inputs for 600-ohm balanced telephone line, LO-Z balanced microphone, and background music
• Music input (RCA jack or screw terminals)
• Integral automatic level control (ALC) 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 back- ground 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
• Separate 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 are available for the TPU35B/60B/100B models; 25V and 70V outputs are available on the TPU250
• VOXsensitivity level control eliminates transmission of back-ground noise when paging from a telephone
