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

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;

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.
ID1, ID2 are the online network address.
Terminal is network termination resistor, when the device is at the end of network, unplug this
switch.
CAN / RS485 optional:
Down--
: CAN: (CAN_B, 29)
On--
: RS485; (9600, n, 9,1)
