Table 3 AmpliCenter Specifications
! 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.
