SYMPTOM
POSSIBLE PROBLEM
SOLUTION
Crackling sound
from speakers.
Bad connection.
Check all cables. Make sure they are connected to "line-out" or "audio-out"
jack on your sound card or other audio source — NOT "speaker-out."
Volume level in computer operating system is set
too high.
Check the computer operating system volume level and decrease it if necessary.
A problem with your audio source device.
Unplug the stereo cable from the audio source. Then plug it into the
headphone jack of an alternate audio source (e.g., Walkman, Discman or
FM radio).
Sound is
Volume level set too high.
Press the button on the side of the right satellite to decrease the volume.
distorted.
Computer operating system volume level is set
too high.
Adjust the computer operating system volume and balance levels to the
center as a starting point, then adjust the level on the speaker using the
volume control.
Sound source is distorted.
WAV files are often of poor quality. So distortion and noise are easily noticed
with high-powered speakers. Try a different sound source such as a music CD.
Radio
interference.
Too close to a radio tower.
Move your speakers until the interference goes away.
No sound
from subwoofer.
Bad connection.
Check to make sure that all cables are connected properly and are making a
clear connection.
Sound source has little low-frequency content.
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.
Low hum
from subwoofer.
The AC in your house is at 60 cycles per second, which is
within the audio frequency of the subwoofer.
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.
Loud hum
from subwoofer.
Bad connection.
Unplug the AC 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.
Bass level set too high.
Press the button marked with the word "bass" on the wireless remote to
decrease the bass.
Volume or bass level on your audio source device is set
too high.
Disconnect your 3.5mm stereo cable from the audio source. If the loud hum
goes away, lower the volume on the audio source.
Lower the volume or bass level on your computer, portable device, etc.
Distorted monitor.
Subwoofer too close to monitor.
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.
