1. Check the connection of power and main fuse.
2. Measure the mains voltage on the main connector.
3. Check the power on LED.
B. Not responding to DMX controller
1. DMX LED should be on. If not, check DMX connectors, cables to see if link properly.
2. If the DMX LED is on and no response to the channel, check the address settings and
DMX polarity.
3. If you have intermittent DMX signal problems, check the pins on connectors or on PCB of
the unit or the previous one.
4. Try to use another DMX controller.
5. Check if the DMX cables run near or run alongside to high voltage cables that may cause
damage or interference to DMX interface circuit.
C. Some units don't respond to the easy controller
1. You may have a break in the DMX cabling. Check the LED for the response of the master/
slave mode signal.
2. Wrong DMX address in the unit. Set the proper address.
D. No response to the sound
1. Make sure the unit does not receive DMX signal.
