Features
Description
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 ofTPU 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.

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 auto-
matically 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 during a page. Music level
shall be returned to its normal level after a page.
The telephone paging channel shall have a VOX sensitivity
adjustment to eliminate transmission of background noise,
and automatic output leveling (ALC) to compensate for vary-
ing voice levels and paging techniques of persons using the
system.
An Aphex®Aural Exciter circuit shall be included to regener-
ate the harmonics lost during the amplification process. A
control shall be provided to set the level of the Aphex effect.
A night ringer shall be included to alert personnel of incom-
ing calls during non-business hours.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 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. Provision shall be
included to feed a 600-ohm telephone line, LO-Z input or
balanced microphone input of another amplifier, using an
accessory line-matching 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 controls shall be included. A peak level
indicator shall illuminate when the amplifier is driven into
clipping. A power indicator shall also be provided. The ampli-
fier shall operate from a 120V AC, 60Hz source, and shall be
equipped with a resettable circuit breaker and thermal and
electronic overload protection (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 14-3/16" 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-
13/16” D.
