Troubleshooting
No Sound
Is it one speaker or both speakers? If it is the RIGHT speaker only, check that the XD Speaker
Cable is securely fastened between the LEFT and RIGHT speaker. In a subwoofer system, if both
speakers do not product audio, but the subwoofer does, check that there is an audio connection
from the out of the woofer to the input of the speaker pair. If the subwoofer is not working and
audio can be heard from the LEFT and RIGHT speaker, the audio input connections is incorrect.
The audio input connection must be made on the subwoofer first.
If it is both LEFT and RIGHT speakers, verify
the power switch is on and the power cord
is used on an active outlet. The Volume
ring on the LEFT speaker should be
illuminated RED color when the speaker
system is active with power.
After the power is confirmed, check that
the audio input cables are connected
correctly and the audio source is playing.
Be sure the volume level on the audio
source is not set to MUTE or at minimum
level. Be sure the volume knob on the LEFT
speaker is not at minimum level (full
counter‐clockwise). In quiet (low listening
level) situations, adjust the gain stages by
setting the volume to middle or lower and
increase the input level of the audio
source.
The subwoofer features numerous controls to tame low frequency sounds. First, be sure the
crossover setting is in the correct position for the speakers being used. Smaller size speakers
require the crossover to be set at a higher frequency. Larger size speakers require the crossover
to be set at a lower frequency. The BYPASS setting is recommended for use with LFE or
dedicated subwoofer outputs. The subwoofer volume should be set when playing your most
intense bass music (it does not always have to be at max level).
The position of the speakers can contribute to bad sound. Make sure the
proximity of the speakers is not restricted by other objects such as books or
being placed too close to the wall. Experiment by moving the speakers to
different positions and be sure the port tubes are not obstructed.
Verify that all audio related connections are
securely attached. For example, make sure
the audio input connectors are clean and
fully inserted into the jack.
Check that the wiring is not restricted and
not in close proximity to electrical
interference sources such as power cords,
mobile phones or dimming light.
Distorted or noisy sound can result from the
source (computer or portable media player).
Try to listen to the source using a set of
headphones and adjusting the volume to
different levels. If the audio is bad through
the headphones, than the source is the
problem.
