Figure 1: Telephone Paging Amplifier
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.
