Dear Zero88 Forum, i need some help for my Rackmaster 260 dimmers. It seems that some Channels are just starting at 50% to dim up and then they go really fast to full output.  I attached a video that shows the diffcult channels, the both in the mid are dimming perfectly, the others not. Maybe someone could help me. Thanks Stefan 358033363_5127973263994173_7201326826972139299_n.mp4
