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；  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; ○ 13/○ 14 ——Programmable I / O interface (protocol-based) ○ 15 ——CAN or RS485 interface ○ 16 —— System Configuration AMP C1, AMP C2, AMP C2 is configuration of quantity of amplifiers. 0 MIN, 10MIN, 1HOUR, 24HOUR is detection time--No detection/ detect every 10 minutes/ 1 hour, /24 hours.
