FIGURE 2 

ONE CENTRAL AMPLIFIER WHICH HAS MUSIC MUTE, 

PAGE INPUT AND MUSIC INPUT 

(ONE-WAY PAGING AND/OR TALKBACK) 

 
 
 
In this application, the one central amplifier for both paging and background music has music muting and separate inputs (volume controls) for paging 
and music.  The system uses speakers with built-in line matching transformers for both one-way paging, and paging with talkback. 
 
 
 

NOTE 

 
1. 

If the central amplifier does not provide music mute, then the background music source is connected as shown in Figure 3. 

 
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.
