4.4.1 Wiring the Audio Zone Splitter to Amplifiers
This section describes some of the most common ways to use the audio zone splitter.
In all cases, each amplifier provides up to a maximum of 30W.
One Audio Message Application and One Amplifier
Figure 50 shows the wiring of 1 amplifier to the audio zone splitter in a one audio message
application. This configuration provides 9 outputs (1 output on the amplifier and 8 outputs on
the audio zone splitter), and the ability to turn audio zones on and off.

One Audio Message Application and Two Amplifiers
Figure 51 shows the wiring of 2 amplifiers to the audio zone splitter in an application where
both amplifiers play the same audio message. This configuration provides 10 outputs (2
outputs on the amplifier and 8 outputs on the audio zone splitter), and the ability to turn audio
zones on and off.
