Features
Description Bogen models TPU35B, TPU60B, TPU100B, and TPU250 are wall-mounted telephone paging amplifiers
rated at 35, 60, 100, and 250 watts, respectively. All models can also be rack-mounted*. These TPU
amplifiers permit paging from telephone and/or microphone; music input through an RCA jack or screw
terminals; and voice-activated, variable level, music mute with fade back after page. These TPU amps
include a night ringer which sends an electronic ringing tone signal through all speakers, alerting
personnel of incoming calls. Jacks are also provided to bridge two TPU amplifiers to double the number of
inputs and output power.
*B-Models require accessory kit.

The telephone paging amplifier shall be a Bogen Model
___, with a full power rating of ___ watts. (Specify:
TPU35B/35 watts, TPU60B/60 watts, TPU100B/100
watts, TPU250/250 watts.) The amplifier shall provide a
frequency response of ±1dB from 70Hz to 15kHz, and
shall deliver rated power at less than 1% distortion.
The amplifier shall permit paging from telephone and/or
microphone. The signal-activated paging channel shall
automatically mute background music during a telephone
page, eliminating the need for manual activation of
switches and the use of external relays. Provision shall be
included to set to mute the level of background music dur-
ing a page. Music level shall be returned to its normal
level after a page.
The telephone paging channel shall have a VOX sensitiv-
ity adjustment to eliminate transmission of background
noise, and automatic output leveling (ALC) to compen-
sate for varying voice levels and paging techniques of
persons using the system.
An Audio Enhancement circuit shall be included to regen-
erate the harmonics lost during the amplification process
and improve intelligibility. A control shall be provided to set
the level of this effect.
A night ringer shall be included to alert personnel of
incoming calls. The night ringer shall be activated by
a contact closure or by 90-volt ring signal from the
telephone line.
Input terminals shall be furnished for a telephone line and
Lo-Z balanced microphone. A choice of RCA jack or
screw terminals shall be provided for the music source.
Terminals shall also be provided to control music muting,
typically during a mic page, and for contact closure or ring
signal activation of the night ringer. Bridging jacks shall be
provided to bridge two TPU-series amplifiers.
Balanced or unbalanced outputs shall be provided for 16-
ohm, 25V, 25VCT, and 70V speaker lines (for TPU250,
25V and 70V only). Provision shall be included to drive a
600-ohm telephone line, using an accessory line-match-
ing transformer (Model WMT1A).
Individual controls shall be provided to set the telephone
and mic page volume, music volume, night ringer volume,
VOX sensitivity, and music mute level. Bass and treble
controls shall permit tonal adjustments. An automatic
level control (ALC) and VOX sensitivity control shall be
included. A peak level indicator shall illuminate when the
amplifier is driven into clipping. A power indicator shall
also be provided. The amplifier shall operate from a 120V
AC, 60Hz source, and shall be equipped with a resettable
circuit breaker and thermal and electronic overload pro-
tection (TPU250 has a 6A slow-blo fuse).
Installation shall be facilitated by flanges with keyhole
slots for mounting on a suitable backboard. Dimensions
for the 35, 60, and 100 models shall be 14-1/4" W x
8-3/8" H x 3-5/8" D. Dimensions for the TPU250 shall be
19" W x 10-1/2" H x 3-7/8” D.
The amplifier shall carry the necessary safety agency
listings for both U.S. and Canada.
