5. Troubleshooting
Plug in power cord, turn power on.
Verify that there is an input signal from the source.
Verify that there is an output signal.
If there is an input signal and no output signal the
ControlSpace ™ may be muted or the output levels
may be down.
Verify that the audio input indicator is green. If it
is off, increase the source output or the input gain.
If the audio input indicator is green and the audio
output signal indicator is green, verify there is
enough gain in the amplifier and check output
levels.
If the input source signal is clean when it enters
the CS AMS-8 system, verify that the loudspeakers
are not being overdriven and are not damaged.
Verify that the correct speaker EQ and/or crossover
are used in the signal path.
Check all connections on the CS AMS-8 system
rack.
Check the amplifier is operating correctly and
gains are adjusted appropriately.
Verify the default settings and maximum volume
settings of the room in the installer software or on
the system rack.
Check cabling between PC-soundcard, microphone
and system rack. Check volume control settings of
the PC itself.
Check the cabling between CS-WC/CS-PP and
the system rack. In the room settings menu of
the system rack, the status of the wall controller
is shown. If it shows 'WC-', then there is no
communication with the specific wall controller.
Verify the number of the wall controller and, make
sure the wall controller number is set to
the room number it should serve.
Check the RS232 pinout of the cable. Reduce the
length of the cable (10m Max.). Make sure the
installer version shows the connection is online.
