I was pulling a show down yesterday and I noticed two S4s ghosting. I asked the LD about it and he wasn't sure about why it was. I started to ask about it retaining a DMX signal and he cut me off. It seemed he thought since the DMX had been disconnected it couldn't happen. To be honest, I wasn't sure so I thought I would check. If the DMX is disconnected from the dimmer to the board, but is still connected from the dimmers to the trusses, can it ghost?
