Question OT electricians - I need a way to make lights brighten and dim to music.

I'm rigging up a portable stage setup for a friend's band, and basically just need something that brightens as the room volume rises, and dims as it falls. I don't need lasers, fog machines, chasing lights, patterns, etc. Basically just a panel of christmas lights/rope lights/other cheap fixtures that has a sound activated dimmer.

Is there a simple solution, or is this something I need to shell out bucks for on fancy controllers and whatnot?

Yeah, I saw that...I was just wondering if there's something even stupider simple.

Like a Clapper, that doesn't go all the way on or off.

Anything simpler will probably have issues.....and issues have a tendency to lead to fires. Really though, that's a great price for 4 independently controlled 5A outputs. Plus it provides manual control, which would be good. This all assumes it does what you want though, it may do the exact opposite. And the manual link is broken so I couldn't verify.

Yes it is. A small investment in your business, goes a long way to getting a positive result.

He also said he doesn't want those (see first post), but I was only commenting on the cheap part.

Find a way to attenuate a 0-1V (or whatever output your audio is) to a 0-110V scale. I dunno if there is an AC amp but it might work.
