Power outlet: When use the amplifier, should check whether the selected voltage is cor-
rect or not, if the voltage is wrong, it could damage the amplifier, please ensure the device

sponding channel and output connector are connected together to provide the fixed
connection, do not need to consider the power switch setting.

amplifier or the continuous input signal), the button of the circuit breaker will immediately
upspring, and will power off automatically to protect the amplifier. And you must exclude
overload condition, and then press the button of the circuit breaker, and the power amplifi-
er can resume to normal operation.
Channel mode switching switch:
Mainly complete the switching of MONO mode and BRIDGE/PARALLEL by adjusting. There are M1/M2/
M3 three dial switches on the rear panel, shown as M1 silkscreen, when M1 dial switch faces up which
means CH1 is parallel to CH2, when it faces down which means it is off. M2 and M3 dial switch are the
same principle. Key switch function: when key switch faces down which means CH1 is parallel to CH2,
when it faces up which means it is off.
