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
The power light does not turn on
The power light turns on, but the
amp does not make sound
Hum or Noise comes from
loudspeakers
Passive loudspeaker does not
work
Passive loudspeaker is quieter
than master loudspeaker
Correction
Check the power source and power input cable.
The battery in the remote control may be flat.
To test if it is turn the volume dial on the back-
panel of the master loudspeaker up. Alternately,
you may have a cable problem. To narrow down
where the problem is bypass the installed input
cables and plug a input device (such as a laptop
via the headphone jack) directly into the master
speaker. Make sure the output volume on your
test device is at full and that it works through
the laptop speakers before you plug it in.
Check that all input cables shielded properly.
Poor quality cable has uneven shielding which
introduces noise.
Check the speaker cable. Is there a proper
connection at both ends.
This is typically caused by the use of incorrect
cable between the master and passive
Loudspeakers. It is too thin, or shielded. Replace
immediately.
