Telephone Paging Amplifier
Figure 1: Telephone Paging Amplifier
Introduction
This document describes the Avaya 250-watt Telephone Paging Amplifier. These are full-featured, wall-mounted amplifiers that provide inputs for dry loop 600-ohm telephone page signal, background music source, and low impedance microphone. A set of control inputs allow an external contact closure to mute background music and open the telephone page channel. Background music mute level during 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.
