Problem
Possible Cause
Solution

The fuse is blown
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.
Power cable not plugged in
Check if the power cable is
properly connected to the device
and plugged into an active power
socket.
The device is not reacting to DMX
signals
Incorrect DMX start address
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
Make sure the polarity switch on
the DMX controller is set correctly
Try to reverse the DMX polarity
switch on the DMX controller.

no DMX signal indication

connected properly and are not
defective. Replace if necessary.

increase the low-frequency level.
The built-in microphone is not
triggered by high tones.

minimal
Dirty or dusty optics
Clean the lens and/or other optics.

master dimmer is completely open.
Also, check the colour balance
settings.

interrupted and some devices are
flashing or behaving strangely
Damaged/defective cables
Check and replace the DMX
cables if necessary.
