Problem
The subwoofer isn't
working.
The subwoofer hums.
Playback is noisy.
The sound seems flat.
00800 - 200 300 40 (free of charge). Please also observe the warranty notes.
Possible cause
The subwoofer is off or doesn't have any
power.
The overload protection has been trig-
gered and the indicator lamp 10 "CLIP"
is illuminated in red.
Fuse defective.
The volume has been set too low.
The subwoofer is connected to a different
power circuit from the rest of the system.
The buzzing is caused by problems with
the power supply.
The buzzing is caused by a multiple
socket.
Generally speaking, the System 4 is very
low noise. In the high range area, very
high-resolution speaker systems can ex-
pose the poor quality of a signal source
(e.g. from MP3 files).
Satellites have been connected with the
poles reversed.
Attention Risk of damage!
Using the wrong cleaning materials may dam-
age the delicate surface of the case.
• If possible, only use plain water without any additives.
In case of stubborn marks, a mild soap solution may
be used.
• In no circumstances should caustic cleaning products,
white spirit, thinners, petrol or similar be used for
cleaning.
Solution
Switch on switches 4 and 9 ("On"). Check the
power cord and socket.
Allow the unit to cool down and reduce the level
slightly using control 1 "VOLUME".
1.
Disconnect the power
cord.
Carefully pull the fuse
holder out of the mains
connection.
Increase the volume using control 1.
Connect the subwoofer and AV receiver to the
same power circuit.
Purchase a line filter and connect both units to it.
Use another multi-outlet power strip or connect
the subwoofer directly to the wall socket. It may
also help to insert the power plug the other way
around.
Make sure that the source is emitting a clear
signal.
Check that the speaker cable on all satellites is
correctly connected.
