Solution
Adjust the bass level on the front of the right satellite. Many .WAV and .MID
files often have little low-frequency content and sound flat when you listen
to them on a computer. Try a song with more bass—something from your
CD collection.
Move your speakers to see if the interference goes away. If not, you may be
able to purchase a shielded stereo cable from your local electronics store.
Some low hum may be detected when your speaker system is powered on
without an audio source playing, or when the volume is set at an extremely
low level.
Unplug the power cord from the surge protector (if used), and plug directly
into an AC wall outlet.
Move your cables. Check to ensure they are making a clear connection.
Lower the volume or bass level on your computer, portable audio device, etc.
Increase the volume on the audio source.
Check to make sure all cables are connected properly and are making a
clear connection.
Increase bass level on front of right satellite.
Decrease the bass level on front of the right satellite.
Because the subwoofer is not magnetically shielded, it can cause distortion if
it's too close to your monitor. Move the subwoofer so it's at least 2 feet from
your monitor.
