heere is a fun one for you all. a week ago I had a concert with 4 MAC650s with conventionals, controlling them through a Colortran innovator 600. DMX ran trough a spillter then to the fixtures with a total run of approx. 300'. The fixtures were unresponsive and kept moving on their own. I was getting control sometimes but then it would not respond and they fixtures would do there own thing again. I put a GAM check in line to see if I was getting any wierd signals, didn't see any. What it did do was cleaned up the signal to the Macs. This was the first time in four years that I have used Automated lights through my console, and used my DMX splitter.
