The subwoofer hums.
The subwoofer is connected to another
circuit than the rest of the system.
Connect the subwoofer and AV receiver to
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 multi-outlet
power strip.
Use another multi-outlet power strip or plug
the subwoofer directly into the wall socket.
It may also help to insert the plug into the
socket the other way round.
Playback is noisy.
In the high range area, very high-quality
high-resolution speaker systems can in
most cases 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.
Speakers have been connected with incor-
rect polarity.
Make sure all speaker cables are connected
properly.
