Figure 1a: TPU250 Telephone Paging Amplifier Telephone Paging Amplifier Introduction This document describes the Bogen TPU35B, TPU60B, TPU100B (See Fig.1) and TPU250 (see Fig.1A) Telephone Paging Amplifiers. They are full-featured, wall-mounted amplifiers that provide inputs for dry-loop, 600-ohm telephone page signal, background music source, and low impedance microphone.
Installation Figure 3: Rack Mounting the TPU250. Figure 2: Wall Mounting the Amplifier See NOTE below for information on alternate orientation. Screw #8 x 5/8” (M4 x 16mm) with Screw #8 x 5/8 “ (M4 x 16 mm) with Rack Mounting Screws Synthetic washer 1/8”...
The music input is a mono unbalanced input, so the music sourceʼs output should be unbalanced and mono. If a balanced input is needed, use a Bogen Line-Matching Transformer WMT1A (sold separately) to balance the music input. The WMT1A is also effective in breaking ground loops that cause hum.
Input Wiring Connections Night Ringer Connection Either a standard telephone (analog) ring signal (90 – 105V AC, 20 – 30 Hz) or an external contact closure activates the night ringer function of the amplifier. To activate the night ringer using standard telephone (analog) ring, connect the analog station's tip lead to the TEL RING "T"...
Output Wiring Connections All output wiring connections are made to the terminal strip located under the right side access panel. Loosen the two Phillips-head screws on each side of the cover and remove the cover. IMPORTANT: Before making any connections or wiring changes to the amplifier or any equipment connected to the amplifier, make sure that the amplifier is NOT plugged into an AC outlet.
Operation Indicator LEDs The POWER LED illuminates whenever AC power is applied to the amplifier (there is no power switch on the amplifier). POWER The PEAK LEVEL LED illuminates whenever the speaker output signal level approaches its maximum level. This indicator is used when setting PEAK LEVEL volume levels.

Operation RINGER VOLUME adjusts the level of the night ringer tone output. The RINGER VOLUME music volume level should first be set to the customer's satisfaction. When adjusting this level, the PEAK LEVEL indicator should be used to ensure that the amplifier signal is not distorted. MUSIC MUTE adjusts the level of the background music heard during a MUSIC MUTE paging announcement.
