Specialized Telephone Input
The TPU-Series’ 600-ohm transformer bal-
anced input is perfectly suited to connect to
paging ports and paging adapters such as
Bogen’s TAMB2. Here are a few specially
designed features:
• The background music will mute when-
ever paging activity is present on the
telephone input, even if control contacts
are not available. (Separate mute control
contacts are also available.)
• To avoid problems with noise on the lines
falsely muting the background music, a
built-in VOX threshold control (not on
TPU15A) lets you decide what’s a real
signal and what’s noise.
• Because not everyone speaks at the same
level, the Automatic Level Control
feature keeps loud voices from booming
out of the paging system’s speakers.
Audio Enhancement
Crisp, clean, intelligible sound is the goal of
every paging system. The audio enhance-
ment circuit adds back the high frequency
harmonics that are lost through the hand-
sets and speakers. With one simple control,
you can adjust the amount of high fre-
quency content the audio enhancement cir-
cuit adds back until optimum intelligibility
is reached.
Variable Music Mute
Add some polish to announcements by
using the TPU’s built-in variable mute fea-
ture. Variable mute allows you to control the
level of the music heard in the background
during a page. It’s fully adjustable from no
muting of music to full suppression of
music. The TPU also gracefully fades the
muted music back in after the page is fin-
ished for a smooth, professional sound (not
available on TPU15A).
Bridging
Bridging two TPU amplifiers permits them
to be used in tandem with one another to
increase the total output power of the sys-
tem, thereby permitting additional speak-
ers to be added. For example, when two
250-watt amplifiers are bridged, the total
output capacity of the system is 500 watts.
Also, both amplifiers will receive the same
input signal, amplify it, and deliver it to the
speaker loads connected to each
amplifier (not available on TPU15A).

Bogen’s TPU-Series of amplifiers are the ideal choice within the telephone paging industry.
With five models to choose from, ranging in power from 15 watts to 250 watts, each model
provides signal-activated, automatic muting of background music during a telephone page,
and gradual return of music following a page.
P r o d u c t F e a t u r e s :
• 15-, 35-, 60-, 100- and 250-watt models
specially designed for telephone
paging systems
• 3 inputs on TPU250 and TPU-B models:
1 TEL, 1 MIC (Lo-Z), 1 AUX (Hi-Z)
• 2 inputs on TPU15A: 1 TEL, 1 AUX (Hi-Z)
• 600-ohm balanced TEL input for direct
connection to page ports and adapters
• TEL input has Automatic Level Control
(ALC) for constant page announcement
level
• Separate MIC input for a low-impedance
push-to-talk microphone
(excluding TPU15A model)
• Audio enhancement circuitry (excluding
TPU15A model)
• Music input – mutable by external contact
closure (excluding TPU15A model) or
activity on TEL input
• Separate volume controls for mic, paging,
background music, and night ringer
• Built-in night ringer can be activated from
90V ring signal (excluding TPU15A model)
or external contact closure
• 25V and 70V constant-voltage outputs,
balanced and unbalanced; also 8-ohm
on TPU15A
• Wall-mount design provides minimum
protrusion from backboard
• TPU-B models may be rack-mounted using
RPK82 rack mounting kit (sold separately)
• TPU250 designed to rack mount directly,
no kit necessary
• Easily accessible, recessed front-panel
controls (excluding TPU15A model) for
setting volume, muting, music, etc.
• RCA jacks provided to allow amplifier
bridging to double the number of amplifier
inputs and outputs (excluding TPU15A
model); a TPU250 can only be bridged
with one other TPU250
• Thermal and electronic overload protection
(excluding TPU15A model), resettable circuit
breaker (except TPU250), Slo-Blo fuse
on TPU250
• Listed to UL Standard 60065
for US and Canada
