Troubleshooting
TROUBLESHOOTING
1. SYMPTOM: NO SOUND COMING OUT FROM THE
SPEAKERS
Probable causes:
1. The A/C power of the speaker is turned off.
2. Wrong A/C power selection (i.e. 110V~ 220V).
Remedy:
A.
Turn on the A/C power of the speaker.
B.
Make sure the receiver or amplifier 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
that 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 SOUND COMING OUT FROM ONLY
ONE SPEAKER
Probable cause:
The A/C power of the speaker is turned off.
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,
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 another speaker 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. 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 for
further information. If the problem is with the speaker, consult
your dealer for further assistance, or visit our web site for
technical support.
3. SYMPTOM: NOISE FROM THE SPEAKER.
Probable cause:
The A/C power cord of the speaker is not grounded.
Remedy:
Change a new magnet cord of the A/C power cord.
4. SYMPTOM: MICROPHONE VOLUME IS TOO LOW.
Probable causes:
A.
The microphone is poorly connected to the speaker.
B.
The volume on the speaker is too low.
Remedy:
A.
Check the connection between the microphone and the
speaker. Make sure that they are connected properly.
Condense microphone doesn't work with the speaker. You
may need to change to a dynamic vocal microphone.
B.
Turn the volume to an appropriate level. If the volume is
still not high enough, you may need to upgrade your existing
audio system to a system with much higher output.
5. SYMPTOM: CRACKING NOISE FROM THE SPEAKER.
Probable cause:
The tweeter may be burned out.
Remedy:
Replace with a new tweeter.
Note: we recommend hiring a professional to change a
tweeter in order to do it properly.
6. SYMPTOM: SOUNDS LIKE DAZZ, DAZZ, DAZZ ........
COMING FROM THE SPEAKER.
Probable cause:
The speaker cable (with small gauges) is over 100 feet.
Remedy:
Change to a higher quality cable preferably 12 and 14
gauges.
