1-8 Overview

Features and Capabilities
The following list provides an overview of the features of the PagePac
Plus AmpliCenter.
Amplifies paging — The AmpliCenter amplifies the page in increments
of 20 watts (D20), 100 watts (D100), or 300 watts (D300) for a 70V
constant voltage distribution system.
Paging input — The AmpliCenter accepts inputs from PBX trunk ports,
dry loop page ports, or amplified microphones.
Music interface — The AmpliCenter is the unit to which the background
music source (CD, radio, tape player) is connected, for distribution to
the paging system.
Volume control — The AmpliCenter has music ducking (mute) level,
music volume level, and bass control adjustment pots on the rear
panel. Overall output level can be controlled by dialing a DTMF code.
Remote amplifier connection — The AmpliCenter provides 0 dBm
audio output for connection to a remote amplifier, which receives a
contact closure control signal from the AmpliCenter.
