TROUBLESHOOTING
1. SYMPTOM: NO SOUNDS COMING OUT FROM THE
SPEAKERS
Probable cause:
1. The A/C power of the speaker is not turned on.
2. Choose the wrong A/C power selection (i.e. 110V~
220V).
Remedy:
A.
Turn on the A/C power of the speaker.
B. Check the receiver or amplifier if it is on and the source is
playing.
C. Check all wires and connections between receivers,
amplifiers and speakers. Make sure all wires are connected.
None of the speaker wires are frayed, cut or punctured, and
no wires are touching each other.
D. Review proper operation of your receiver or amplifier.
E.
Choose the right A/C power.
2. SYMPTOM: NO SOUNDS COMING OUT FROM ONLY
ONE SPEAKER
Probable causes:
The A/C power of the speaker is not turned on.
Remedy:
A.
Check the "Balance" control on your receiver or amplifier.
B.
Check all wires and connections between receiver,
amplifier and speaker. Make sure all wires are connected.
Make sure none of the speaker wires are frayed, cut or
punctured, and that no wires are touching each other.
C.
In Dolby ® Digital or DTS ® mode, make sure that the
receiver or processor is configured so that the speaker in
question is enabled.
D. Turn off all electronics and switch the speaker in question
with one of the other speakers that is working correctly. Turn
everything back on, and determine whether the problem is in
the same place: i.e., the speaker that was working previously
now has no sound and the speaker that was not working
now sounds fine; or whether it has moved; i.e., the speaker
that was not working still has no sound and the speaker that
was working is still fine. If the problem is in the same place,
the source of the problem is most likely with your receiver or
amplifier, and you should consult the owner's manual further
information. If the problem has followed the speaker, consult
your dealer for further assistance, or visit our web site for
technical support.
