I am having a horrible time with my Elation Spot 575E. They are acting very erratic and no matter what I do I cant get them to behave. The DMX is running out of LEDs and then into the Elations. All I did was take down 4 martin manias and hang 4 elations. The manual I have for the Elations has the older LCD screen for addressing and the elations I have, have the new High tech blue screen on the front. Any suggestions?
