Protection against shor t circuits, no-load, on/off muting, RF interference.
Flow-through ventilation from front to back
Internal heat sinks with forced air. Fan cooled, speed regulated,
thermal protection
Plug Wire:：10A，250V 3x1.0mm
Power switch: It can turn on/off the amplifier. When turn on, the POWER
LED lights.
SIG
POWER
Fault LED: When circuit protection works, the LED will light, especially
when the heat-sink overheat or detect the DC voltage in the amplifier,
the LED will light. Turn on the amplifier within three seconds, the
amplifier is ready to work, the LED will shine. When finish start or the
problem is removed, the LED will extinguish, and resume working
normally.
FLT
CLIP
Clip LED: When the output signal distortion of the corresponding
channel exceeds 1%, the LED will light, because of the signal level
is too high, and have been cut-off.
Signal LED: when there is the input signal, the LED will light, if not,
please check the gain settings, if necessary, can increase the gain.
Check the input connection and signal audio source. If the Clip LED
shines a little or shows no signal, check the output wire whether it is
short-circuit or not.
