4. SYMPTOM: NOISE/SIGNAL COMING FROM
SPEAKER(S)
Possible causes:
• The A/C power cord of the speaker(s) is not grounded
• Audio source is presenting a short circuit
• Audio cable is damaged
Remedy:
A.
The product comes with a standard 3-prong A/C power
cable; do not remove the grounding prong in order to
connect to a two-prong power outlet. By removing the
grounding prong interference is no longer eliminated.
Removing the grounding prong not only voids the
warranty but could results in injury or even death.
B.
The audio source is generating noise and sending the
signal to the speakers. Test a new audio source for proper
operation.
C. The audio cable is contacting opposite leads and causing
interference; replace the audio cable for a higher quality
audio cable.
5. SYMPTOM: CRACKLING SOUND COMING FROM
COLUMN SPEAKERS
Possible cause:
Tweeter(s) may be damaged.
Remedy:
Replace tweeter. We recommend hiring a professional to
change the tweeter properly.
6. SYMPTOM: SOUNDS LIKE DAZZ, DAZZ, DAZZ ........
COMING FROM SPEAKER(S)
Possible cause:
The speaker cable (with small gauges) is over 100 feet.
Remedy:
Change to a higher quality cable, preferably 12 and 14
gauges.
7. SYMPTOM: TOO MUCH MICROPHONE FEEDBACK
FROM SPEAKER(S)
Possible cause:
Incorrect tremble and bass adjustments on the speaker.
Remedy:
Adjust the tremble and bass to an appropriate level to avoid
microphone feedback.
8. SYMPTOM: SPEAKERS SOMETIMES HAVE NO SOUND
Possible cause:
When the master volume reaches the maximum level, the
speaker automatically shuts down because it has a built-in
auto circuit to protect itself when the master volume becomes
too high.
Remedy:
Change to a higher power amplifier to work with the
speakers. Be sure the output power of the amplifier matches
the speakers. Another option is to add more speakers or
subwoofers for higher output as below.
1. Add one more loudspeaker.
2. Add one more powered subwoofer.
We highly recommend hiring an audio professional for
advise on the right engineering for the amplifier and
speakers.
