Turn the bass level rotary knob to the right to raise the subwoofer volume.
Check volume level on the audio source device, and set at mid-level.
Connect audio cable from the audio source. Check plug connections on both
the subwoofer and source. Make sure these signal cables are inserted firmly
into the correct jacks.
Check connections to ensure that one cable is connected to the audio outputs
on the audio source and the input on the XA3001.
Check that the other cable is connected to the outputs on the XA3001 and the
audio input on the TV.
Test the speakers using another audio source.
Check all cables. Make sure they are firmly connected to the “line-out” or
“audio-out” jacks on the audio source.
Unplug the cable from the audio source. Plug it into an alternate audio source,
then listen closely to the sound to determine if the crackling sound disappears.
Decrease the volume on your TV, bass level on your XA3001 subwoofer, or
volume on your audio source (if possible.)
Try a different sound source like a music CD.
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 shop.
Adjust the bass level on the subwoofer.
Try a game, movie song - anything with more prominent bass tones.
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.
If you are using a surge protector with your subwoofer, disconnect and plug
the XA3001 power adapter directly into an AC wall outlet.
Move your cables. Check to ensure they are making a clear connection.
Disconnect your stereo cable from the audio source. If the loud hum goes
away, lower the volume on the audio source.
Adjust the bass level on the subwoofer.
Verify that all cables are connected properly and are making a clear connection.
Decrease the bass level on the subwoofer.
Because the subwoofer IS NOT magnetically shielded, it may cause distortion if it
is placed too close to your monitor/TV. Move the subwoofer so it’s at least 2 feet
from your monitor/TV.
