Has anybody ever encountered a problem like this? Whenever our lighting board is off and the power to our sound system is turned on, whatever lights are on go black for about one second, then come right back on. BUT, if the light board is already on, this problem does not occour. BUT, if the DMX cable is removed from the light board, while it is off, the problem does not occour. Anybody seen anything else like this? Lighting system is a Lehigh DX2 system with 6 preset recall stations, a CT500 Master Touch Station, and MillenniumXP console. This is pluged into a surge protector. Sound system is protected by a NADY PCL power conditioner, and supplies a Soundcraft Venue Theater board, and 2 Numark CD Players. Thanks for your help!
