TROUBLESHOOTING
If your system is not operating properly, please refer to the following information. If the problem
persists, disconnect from power and contact your AV reseller immediately.
Problem
Sounds Hollow /
No Bass
Distortion /
No treble
No sound /
Sound only coming out
on one side
Correction
Check that you've connector the speaker cable polarity
positive-to-positive and negative-to-negative.
Distortion can be caused by poor gain structure. Ensure the
gain (volume) on your source device is at 100%, and turn the
amplifier down.
If the problem still persists determine if both speakers are
distorting the sound. If it is only one it is likely you have a
damaged driver and you should contact your AV reseller
immediately. If both are outputting distorted sound the
problem is more likely to lie with the amplifier.
You should take these steps to narrow down where the
problem lies:
Step 1:
Bypass the faceplate inputs by plugging an audio source
directly into the amplifier. In the case of the Techconnect
Amplifier for example plug in iPod into the front input,
ensuring that the iPod is turned to full volume.
If the problem has gone away the fault is with your input
connections.
Step 2:
If the problem still persists then swap the Left and Right
output connectors on the amplifier.
a) If only the left speaker was working, and now only the right
speaker is working, you know the speakers both work and the
problem is with the amplifier.
b) If only the left speaker was working, and after switching
the left speaker is still the only one working, then you know
the problem is with the right speaker.
