Features:

* Built-in 500W amplifier, with 8 zones and A+B independent dual speaker loop output, each zone has independent LED indicator light, output control button and volume adjustment.

* Audio processing with 6 general audio inputs and 1 MP3 input, it can connect with external microphone, CD player, tuner and etc, it can play any audio source in any zone. Among them, 2 channels have 24V phantom power microphone input, 4 channels are AUX input and 1 channel is MP3 audio channel from the controller.

* With fault self-check of power-on system, and fault full check of manual system function.

* With real-time indication of system status.

* Connecting with one backup amplifier, when built-in amplifier damaged, it will switch to backup amplifier automatically.

* Automatically monitor every zone speaker loop status (open circuit, short circuit) in real-time.

* 8-channel short-circuit/level trigger mode, the trigger response can be configured with 3 different channels of EVAC, ALERT, and LINE3, and the output can be arbitrarily configured with partition, group, and short-circuit contact combination.

* Support external 24V backup power supply, realize power-off continuous normal operation without delay;

* Extension port can connect controller and next extension device.

* The partition output has three-wire and four-wire forced-cut adjustment functions;
