Bogen TPU15A Data Sheet

The Bogen Model TPU15A is a unique 15-watt, wall-
mounting amplifier, specifically designed for telephone
paging applications. This compact unit incorporates
state-of-the-art electronic technology. It provides
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. A built-in night ringer can be triggered by an
external contact closure, alerting personnel of incom­ing calls during non-business hours.

Installation and maintenance are simple; all connec­tions, adjustments and mounting are accomplished
with a screwdriver. Input terminals are furnished for a
600-ohm balanced telephone line, a background music
source, and dry contacts which, when closed, trigger
the night ringer. Output terminals offer a choice of 25
volts, 70 volts, or 8 ohms for connection of various
types of loudspeakers.

The Model TPU15A features an LED overload indica­tor, a low-cut switch for use with horn loudspeakers,
a push-to-reset circuit breaker, and individual controls
for tone, page volume, background music volume, and
night ringer volume.The unit is professional in styling,
finished in black with silver lettering. It operates from
a 120V AC, 60Hz source.

Technical

Specifications

The telephone paging amplifier shall be a Bogen
Model TPU15A, or equivalent, with a power rating of
15 watts. Distortion shall be less than 2%. Frequency
response shall be ±2dB from 70Hz to 12kHz for the
music channel and the page channel shall be shaped
for maximum intelligibility. Sensitivity shall be -20dBm,
600 ohms for the page channel, and 70mV for the
music channel. Signal-to-noise shall be -70dB ("A"
weighted). Tone control action shall be -3dB at

2.5kHz; 6dB per octave; the low-cut filter action shall
be -3dB at 350Hz; 6dB per octave. The amplifier shall
provide a 600-ohm balanced page channel input, and
a 25-kilohm, unbalanced auxiliary/music channel input.
The page channel shall incorporate automatic level
control (ALC) limiting output level change to +1,

-3dB with 15dB input level change (ref.-20dBm rated
input sensitivity). The amplifier shall also provide a
night ringer, which shall be triggered by an external
contact closure. Outputs shall be 25V, 70V, and 8
ohms balanced and transformer-coupled.

The amplifier components shall be completely solid­state and the unit shall mount directly to a wall.
Electronic circuitry shall provide voice-activated mut­ing of background music during a page. Amplifiers
that require the use of telephone system-supplied
external relays shall not be accepted.

Screw terminal barrier strips shall be provided for all
input and output connections. Individual controls shall
consist of Page Volume, Music Volume, Night Ringer
Volume, and Tone, all of which shall be screwdriver­adjustable. A Peak Level LED indicator, Lo-Cut filter
switch and a circuit breaker shall be provided.

The amplifier shall operate from a 120V AC, 60Hz
power source. The unit shall be professionally fin­ished (silver on black) and shall measure 11" W x
2-3/4"H x 2-3/8"D. The shipping weight shall be four
pounds.
