Bogen TPU-15A User manual

The Bogen Model TPU15A is a unique 15-watt, wall-
mounting amplifier, specifically designed for telephone
paging applications. This compact unit 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.
Installation and maintenance are simple; all connec-
tions, adjustments, and mounting are accomplished
with a screwdriver.

unbalanced auxiliary/music channel input. The
page channel shall incorporate automatic level con-
trol (ALC) limiting output level change to +1, -3 dB
with 15 dB input level change (ref. -20 dBm 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 mount directly to a
wall. Electronic circuitry shall provide voice-activated
muting of background music during a page.

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
screwdriver-adjustable. A Peak Level LED indicator,
Lo-Cut filter switch and a circuit breaker shall be
provided.
The amplifier shall operate from a 120V AC, 60 Hz
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 product weight shall be four
