Hey All,
Random problem that has been happening recently. We have a 1300 seat high school auditorium, built in 1996. Recently our lighting dimmer 73 hasn't been working, no problem, we have a ton of extra nearby that we can use until that is fixed. The weird issue is whenever dimmer 73 has power applied to it, it creates a nasty hum/hiss in the audio system. I know the two systems are seperated electrical (isolated transformers, etc), so I can't figure out why it would be humming. I've looked at dimmer 73 plug, nothings wrong. I can't imagine the wire between the plug and the dimmers would randomly go bad (we haven't had any construction or anything recently).
My role is TD, and we have in house electricians, but I need to at least point them in the right direction towards the problem. Any ideas? Thanks!
(FYI, don't know how the title got changed to "humconst", should be hum)
