Introduction
This document describes the Bogen TPU250 250-watt Telephone Paging Amplifier
(see Figure1).This is a full-featured, wall-mounted amplifier that provides inputs for
dry loop 600-ohm telephone page signal, background music source, and low
impedance microphone.Automatic music mute is provided when making a telephone
page. Background music mute level during a page is adjustable and the music slowly
fades back in after the page is completed. An automatic level control system limits
the output level of the telephone page channel so that differences in the volume of
the paging party's voice will be less noticeable. Bass and treble controls are provided
for adjusting the quality of the output signal. An Aphex
®
Aural Exciter feature is also
provided. Aphex improves the clarity of the output signal by replacing the higher
frequency harmonics that are normally lost through the telephone system. This
amplifier includes a built-in night ringer that can be triggered by either a standard
telephone (analog) ring signal or an external contact closure. The night ringer mutes
the background music, but not pages.
