Equipment Introduction.
1.1. Front Panel/ Rear Panel
○
1 —— Power switcher
○
2 ——Power Led Indicators
Blue —— Normal power supply；
Off —— Power failure；
○
3 —— Main Amplifier channel status indicator
Yellow——Amplifier Failure；
Off——Amplifier not in configuration or not exciting；
Red——Main Amplifier change over to standby Amplifier；

7/9
Green——Normal working；
○
4 ——Speaker zone indicator Led
Yellow——Failure；
Off——Normal working；
Red——Earthing；
○
5 —— Indicator of standby amplifier
Yellow——Standby amplifier Failure；
Green——Normal working；
Other undefined；
○
6 —— Speaker loop impedance checking; keep press 5 seconds then release, this is speaker loop
impedance checking, press 1 second then release, this is 8 lines real-time impedance detection.
Note: When the speaker loop impedance was changed, check at least once (the change means
increase or decrease the speaker)
○
7 —— Standby power amplifier balanced signal output (external power amplifier balanced input
interface, pay attention to external unbalanced input interface, "+" connect to "+", "-" connect "G" first
then connect unbalanced “G”, which will lead to signal reduce to half)
○
8 —— Main amplifier 01 ~ 08 balanced signal output interface (external power amplifier balanced
input interface):
○
9 —— External power amplifier (standby) 100V input interface;
○
10 —— External main function 01 ~ 08 amplifier 100V input interface;
○
11 ——Zone output, connect to speakers (please note speaker is 100V);
○
12 ——Device fault output interface
When the device’s zone speaker line has open circuit, short circuit, ground, or main amplifier ,
standby power amplifier is fail, the relay output is open, if normal working, the relay is closed;
○

○
15 ——CAN or RS485 interface
○
16 —— System Configuration
AMP C1, AMP C2, AMP C2 is configuration of quantity of amplifiers.
