Problem
Cause
Solution
You have a ground loop
problem.
Try using the provided cheater plug. Do NOT ground
the grounding tab on the cheater plug! That would defeat
the purpose of the cheater plug for this application.
You have an amplifier problem. If ground cheater plug does not help, disconnect all
interconnects from the subwoofer amplifier. If still hums,
call or email technical support.
Humming or Buzzing
Noise
You have a problem with other
equipment.
If hum goes away when interconnects are disconnected,
hum is coming from the rest of your equipment. Add
them back one piece at a time. The one that causes the
system to hum is the source of the hum.
AC power not getting to the
amplifier.
Check that the power cord is plugged in securely at both
ends and make sure that the power outlet the subwoofer
amplifier is plugged into is functioning properly.
No output from the
subwoofer (the Blue
LED does not light
up).
The amplifier s fuse is blown.
Check the fuse. The fuse is located just above the power
plug on the amplifier. Unplug the power cord and remove
the fuse holder with a screwdriver and check the fuse. If
the fuse is blown, replace the fuse with a 20 mm 10A (5A
for 230V) slow blow fuse. If the fuse blows again, the
output transistors are probably damaged. Email or call
technical support for authorization to send the amplifier
back for service.
