Table 4. AmpliCenter Specifications
Features
Telephone Paging Access: The AmpliCenter accepts inputs from telephone system (PBX) ground■
start or loop start trunk ports, dry loop 600 ohm page ports, dry loop (hi Z), 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.
