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
No power light
Power light on but no
sound
Hum or noise
Slave loudspeaker not
working
Slave loudspeaker is
quieter than master
loudspeaker
Correction
Press volume control.
Check power source and power input cable.
Check fuse
Press volume buttons on master loudspeaker to turn up.
Make sure the output volume on your test device is at full and
that it works through the built-in device loudspeakers.
Check that all input cables shielded properly. Poor quality
cable with uneven shielding introduces noise.
Make sure all source devices are connected to the same power
source. If disconnecting a laptop from power solves the
problem then this is definitely the cause of the problem.
Check speaker cable to ensure there a proper connection at
both ends.
This is typically caused by the use of incorrect cable between
the master and slave loudspeakers. It is too thin, or shielded.
Replace immediately.
