Stage Lighting Issues

A bit of an odd one; Has any of you had problems with stage lighting making your Amp hum?
My Peavey Deuce does not like these disco sound-to-light lights we've been using, they cause it to hum and the valves seem to glow more even with the lights a few feet away.

Is this with the amp plugged into a seperate power socket from the sound-to-light unit? If not, maybe trying that might help.

you used the word disco in your post.

........

your amp is rejecting the disco. you should too

I guess the stage light are a helluva draw on the mains supply, maybe the amp isn't getting all the current it needs?

Of the three lights we've been using i think one of them was in the same socket as my amp, i'll look into that, cheers. They dont seem to effect the other amps (Line 6 and Laney) in the band, fucking things, worst thing is they were my suggestion

never had anything with lights but my whammy pedal goes a bit mental if its placed too close to certain things.

i have had strange sounds due to lights like that. try different circuits or something that isolates power.

The lights in my old living room (spot lights with a dimmer switch) made my a lot of noise come from my amp, and it didn't seem to matter which amp, guitar, lead or pedals I was using. It would also cause noise if I was upstairs playing in the upstairs front room (above the lights) and I'd notice that it'd get much worse depending on where I stood and where I allowed the cable to run across the floor, but it was always there.

Don't know how that's any use to you and your problem, but basically fuck lights.

They can definitely have affect your signal - It can happen really randomly though. I know we used to have to sometimes switch the lights off in our practice room so that our amps wouldn't go mental, though it only happened sometimes.

I sometimes sit in my living room and practice with my full setup. If I have the TV on the background and turn the volume up or down, it makes a weird clicking noise through my amp. It's bizarre.

Lighting rigs and fans and all that sort of theatrical stage enhancement is bad news plugged into the same socket as amplifiers. Its something to do with the drain and some other electromagnetic phenomena that I can't quite recall at the moment. Something to do with induction, as far as I remember, but don't quote me.

Put simply: Keep lights on a separate circuit from anything else. Stage lights (especially Lekos (spotlights) and PARs (can lights)) draw a tonne of power (Average 750W each? Jesus... I wouldn't even run two of them on a single circuit). They cause a large amount of interference with audio and video signals due to this fact.

Play in the dark. That's way more metal.
