Front LED is illuminated as red and no sound
When the soft start and DC protection are initiating, the front LED will illumi-
nate as red and there will be no sound. Within one minute the LED should illu-
minate as white and there should be sound. If the LED still illuminates as red:
1. Switch off the amplifier and test again until it cools down. If this does
not work, the amplifier may be overheated. Make sure not to overload
the amplifier. Placing it at where ventilation is better is preferred.
2. If it still doen not work, switch off the amplifier and unplug the input
XLR cable. Short the 3pins of the XLR input socket (you may need
help from technicians or dealers). Switch on again and check if the LED
turns white within a minute. If it does, it means there maybe DC in the
input which triggers the DC output protection. Make sure to have a
pure signal AC input without DC from the source.
3. If all of these steps fail to restore sound, consult your dealer for ser-
vice.
Front LED is illuminated as white but you hear no sound
Switch off the amplifier first. Follow these steps in order. If one step succeeds
in restoring the sound, stop there and ignore the other steps.
1. Check the cables between the amplifiers and the speakers to make
sure they are properly connected and that the cables are not damaged
or shorted.
2. Check your preamp and source device to make sure they are both
turned on.
