FIGURE 5
TWO CENTRAL AMPLIFIERS,
ONE FOR PAGING AND ONE
FOR BACKGROUND MUSIC
(ONE-WAY AND/OR TALKBACK PAGING)
In this application, two central amplifiers are used, one for paging and one for background music. The system uses speakers with built-in line matching
transformers for both one-way paging, and paging with talkback.
NOTES
1. If both the music central amplifier and the background music source have no volume controls, then a PRM-150 must be connected between the
background music source output and the music central amplifiers input.
2. In systems with talkback paging, install one background music source only as shown. DO NOT connect background music source directly to zone
group music inputs.
