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 Correction
No power light Rotate volume control clock-wise.
Check power source and power input cable.
Check fuse in power cable plug.
Power light on but no
sound
Turn the volume dial on the master loudspeaker up.
Make sure the output volume on your test device is at full and
that it works through the built-in device loudspeakers.
Hum or noise Check that all input cables shielded properly. Poor quality
cable with uneven shielding which 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.
Try disconnecting one input. The inputs summed inside the
SP-800P so are both live at the same time.
Slave loudspeaker not
working or quieter
Check speaker cable to ensure there a proper connection at
both ends.
Slave loudspeaker is
quieter than master
loudspeaker
This is typically caused by the use of incorrect cable between
the master and slave loudspeakers. It is too thin, or shielded.
Replace immediately.
