Zone Amplifiers, 1 per zone
Each amplifier is for paging and background music in its own zone.
System uses speakers with built-in line matching transformers.

Amplified Speakers
For one-way or talkback paging each amplifier is for paging and
background music for its own speakers.
Existing system renovations and expansions often require different amplifier configurations in different zone groups. For example, an existing central
amplifier paging system may be zoned, and then expanded by adding amplified speakers or zone amplifiers. With the appropriate programming switch
selections, the following are some examples of mixed system possibilities.

NOTE
In mixed systems, the different amplifier configurations must be installed in different zone groups. It is not possible to mix different amplifier
configurations within the same zone group.
The ZC-9 maximum amplifier and speaker capability for each zone and the total system is shown in CHART 6.
