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
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 or crossover is used in the signal path.
Make sure the input signal is not distorted/ too high.
Check all connections on the CS AMS-8 system rack.
Check if the amplifier is operating correctly and gains are adjusted
appropriately.
Verify the default settings and maximum volume settings of the room in
the Live installer software or on the system rack.
Check if Events or Room Combining presets are activated.
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 software shows that the INETGui
connection is online.
Make sure the audio cable is connected to the LEFT output connector
of the CS-LIM.
Make sure to adjust the input gain to 0dB. A constant 3dB input
signal will mute the input stage. E.g.: for a CD-player with an output
signal of +6dB , the input gain should be reduced with at least 3dB
(6dB is prefered).
This indicates a communication problem. Check the communication
cabling between AMS-8 and Paging panel. Make sure the termination
jumper is set at the last CS-PP.
Check the connection between AMS-8 and the CS-PP. Check the routing
settings in the Live Installer Software or on the AMS-8 unit (using the
LCD and navigations buttons).
