information and/or help.

but it does not and cannot cover every eventuality. It is possible that you won't find your problem, cause and
solution in this section because product details may differ.
Problem
Possible cause
Solution
Speaker does not turn on with
mains power
Defective fuse
Check the fuse, which is located
under the power input, to rule out
of it's blown or not. If it is blown,
replace it with a new fuse of the
same type and class.
Problem with the power cable
Check that the power cable is
plugged into an active power
socket and the speaker properly.
Try using another cable of the
same type to determine if there's a
problem with the power cable and
if there is, replace the problem
cable.
Speaker doesn't turn on
Check if the power switch on the
back of the speaker is set to the
'on' position.
Power LED doesn't light up
If the speaker is connected to an
active power socket, the fuse has
been checked and the power
switch is ON but the power LED is
not lighting up, there may be a
problem with speaker itself. In this
case, the speaker should be
turned off again and you should
contact your dealer for assistance.
No sound via one of the inputs
Cable not connected properly
Make sure the cable between your
sound source and the speaker is
connected properly.
Switch in wrong position
If present on the input channel, set
the signal switch to the correct
position for the connected device.
Microphone is not on
Make sure the microphone switch,
if present, is switched on.
No sound from the master output
Volume control is not turned up
Turn up the master control volume
to a sufficient level.
Red Clip Limiter LED lights up
often or continually
Volume is too high
Decrease the volume level on the
speaker or the connected audio
source device. Continuous
exposure to overloading can cause
permanent damage.
