DMX Lighting Troubleshooting
Possible Cause
The fuse is blown
Power cable not plugged in
Incorrect DMX start address
DMX controller is set to 'Blackout'
Make sure the polarity switch on
the DMX controller is set correctly
The device is not reacting, there is
no DMX signal indication
Incorrect operation mode
The internal microphone sensitivity
is too low
The speaker is too far away, or is
not producing enough low tones
Dirty or dusty optics
Dimmer is not completely open
Damaged/defective cables
Power interference on the DMX
signal
DMX terminator missing
Solution
Check the fuse to rule out if it is
blown or not. If it is blown, replace
it with a new fuse of the same type
and class.
Check if the power cable is
properly connected to the device
and plugged into an active power
socket.
Check if the device has been set
to the correct DMX start address
Make sure the 'Blackout' function
on the DMX controller is not
activated
Try to reverse the DMX polarity
switch on the DMX controller.
Make sure the XLR cables are
connected properly and are not
defective. Replace if necessary.
Make sure the sound-activated
mode has been selected.
Check the microphone sensitivity
level and increase it if necessary.
Place the light effect closer to a
speaker (or vice versa) and/or
increase the low-frequency level.
The built-in microphone is not
triggered by high tones.
Clean the lens and/or other optics.
Check if the dimmers on the
spotlights themselves and/or if the
master dimmer is completely open.
Also, check the colour balance
settings.
Check and replace the DMX
cables if necessary.
Avoid connecting signal cables
parallel to power cables.
Close the DMX circuit with a DMX
terminator
