The Bogen TPU Series Mixer-Amplifiers are unique, wall- or rack-mounted amplifiers, specifically designed for telephone paging applications. These compact units provide voice-activated muting of music when paging, completely eliminating the need for manual activation of switches and the use of external relays. The page channel features automatic output leveling (ALC) as channel input varies, which is particularly important in telephone paging applications, where persons with varying voice levels and paging techniques have access to the system. Installation and maintenance are simple; all connections, adjustments, and mounting are accomplished with a screwdriver.
- 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
background music
- Adjustable background music muting level during a
page
- Music gradually returns to its normal level after a page
- Audio Enhancement circuit 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 Audio Enhancement
- Bass and treble controls
- Built-in night ringer activated by contact closure or by
90V ring signal
- Balanced or unbalanced 16-ohm, 25V, 25V CT, and
70V outputs are available for the TPU35B/60B/100B
models; 25V and 70V outputs are available on the
TPU250
- VOX sensitivity level control eliminates accidental
transmission of background noise from a paging
telephone
- Thermal and electronic overload protection
- Jacks provided for bridging additional TPU amplifiers
- Brackets are attached to each model for easy wall
mounting; the TPU250 can also be rack-mounted
with included brackets; TPU-B models can be rackmounted with RPK82 mounting kit (sold separately)
- Peak level indicator lights when amplifier is driven
into clipping
- 120V AC, 60 Hz power source
- Listed to UL Standard 60065 for U.S. & Canada
