I have a 96 channel Cem+ touring dimmer rack which was used by the set crew claiming that when patching or trying to use any of the channels beyond channel 48, that it sometimes skips channels 49-96. I put the main board on test mode all channels lit up. I assuming that the dimmer rack itself is fine, that perhaps its a main board config issue or operator's error on set...any suggestions?
