So I'm now working at a venue on campus called Uptown. The venue is 8 years old. There is a problem with the lighting system. When there is loud music playing, be it from a band or just playing back in someone's ipod, the lights seem to be slightly sound responsive. The stage lights, house lights, all of the lights that are up at all. They get slightly brighter each time the bass pounds. I know that this is not a light board problem for a few reasons: it doesn't do anything with our movers (roboscans of two flavors), it still happens when I tried my own board (Chauvet DMX-70), and it also happens when the light board (NSI MLC16D) is shut down and the system is on architectural control (ETC Unison, button stations, fader station) whether it is in preset mode (scenes 1-4 on the button box) or on manual fader control on the Unison fader panel. So I'm pretty sure that it's not control. The problem apparently began when renovations were done on the building close to and above the venue (venue is in the middle of a large dorm with two wings, one on each side), and the problem only got worse when more renovations were done last year. I am not sure what the nature of these renovations was. Rack is an ETC Unison rack with 10 dimmer modules in it (2x2.4K modules). Lamps involved are regular 120W PAR38 lamps, small halogen tracklight lamps, and 100W or so type A lamps in larger house lights. Any ideas as to what might be causing this? If we have to bring in an outside lighting company to fix it, that's gonna put a huge dent in the budget for next year that I'm trying to get through. I'm hoping that it's something that's just facilities' problem.
