Problem Possible cause Solution
Playback is noisy. Generally speaking, the speakers are very low
noise. In the high range area, very high-reso-
lution speaker systems can expose the poor
quality of a signal source (e.g. from MP3 files).
Make sure that the source is emitting a
clear signal.
The sound seems dull. Speakers have been connected with incorrect
polarity.
Check to make sure the cables of all
speakers are correctly connected.
