POSSIBLE PROBLEM
Speaker is being overdriven by an
amplified audio source.
Noise may be caused by interference
from the monitor.
Volume level on sound card or other
audio source may be too high and
causing speaker to be overdriven.
No power to unit.
Volume level on sound card or other
audio source may be too low.
Signal cable is not completely inserted
into signal jack on subwoofer or
speaker.
NOTE
Depending on your sound card, you may also turn off
amplifier on sound card (check your sound card manual).
If this product is placed too close to a high level source of RF
energy, RF breakthrough may be experienced which can
cause some audio disturbance. If this happens, move the
product as far away as possible from the source until the
disturbance is eliminated. Using an audio input cable with a
high percentage of shielding is also helpful in reducing or
eliminating interference.
For this check, disconnect speakers from sound card and plug
into headphone jack on front of CD-ROM player or alternate
line-level audio source.
Check speakers with another audio
source (CD-ROM player) to see if
sound card or specific file/track may
be problem.
Provided power has been verified, it is possible to test the unit
by pulling out the audio cable that is connected to the
computer and connecting it to an alternate audio source such
as a portable CD player.
Check with an alternate audio source as mentioned above.
If need be, turn cable slightly when inserting to ensure
complete contact.
SOLUTION
Make sure speaker is connected to
line-out jack (unamplified) of sound
card and not speaker-out jack
(amplified); refer to color coding when
making connections.
Turn monitor off to see if noise is
eliminated. Move cables away from
monitor.
Check volume level of sound card or
audio source and lower as necessary.
Make sure all connecting plugs
between the satellite speakers,
subwoofer and computer are fully
seated. Make sure the wall power
outlet or power strip has power. Make
sure the power switches on the power
strip, satellites and subwoofer are
turned on.
Check volume level of sound card or
audio source and raise as necessary.
Make sure signal cables are inserted
snugly into signal jacks.
