Product Description

 

ZONE24 is the zone expansion device controlled by MCU, which adds 24 speaker zones and 24 contact inputs to the

system. ZONE24 can connnect with up to 6 external power amplififiers and 1 backup amplififier. The ZONE24 supports

only single channel audio operation.

Features:

>Supports up to 24 speaker zones

>Single channel operation

>Independent volume control for each audio channel

>500W output capacity for each zone

>Can connect up to 6 main amplififiers and 1 backup amplififier

>Flexible amplififier backup mode, one backup amplififier can be used to back up all the amplififiers in the system

>24 dry contact inputs (non-monitored)

Automatic fault detection: main power, backup power, CPU,

>amplififier,

speaker line, speaker line grounding, dry contact inputs and

>network.

With one line input port, can be used in standalone mode or

>when the controller CPU fails

Can work as stand alone (for PA announcements in case main

Controller CPU fails) or in network mode along with MCU
