the same circuit.
The buzzing is caused by problems with
the power supply.
Buy a line fi lter and connect both devices to
it.
The buzzing is caused by a multiple

Use another multi-outlet power strip or con-
nect the subwoofer directly to the wall socket.
It may also help to insert the power plug the
other way around.
Playback is noisy.
Generally speaking, System 8 is very low-
noise. In most cases, the speaker system
with exceptional resolution in the high
range area can expose the poor quality of
a signal source (e.g. from MP3 fi les).
Ensure that the source is sending a clear
signal.
The sound seems dull.
A satellite has been connected with incor-
rect polarity.
Make sure the speaker cables of all satellites
are connected properly.
