Crack from the amp

[Jayme]

I'm not shore if this is the right room but i'll say it anyway.
can anyone explame why i can hear a crack in my monitors when i turn of my amp? I always have the mixer levels down and it didn't do it before but i moved my studio and now it dose it!
I am going to have a look at it soon but i just want some direction to know where to start?

A few suggestions-
Go to Radio Shack and get a little plug-in outlet tester. This will tell you if your A/C is wired correctly and grounded.

Make sure none of your mic cables, wall warts, line cables, speaker wires are piled on top of your amp. Amps can make a pretty big EM pulse when you turn them on/off, and that can get into your gear through your cables.

Turn your amp all the way down bfore switching on/off. You should do this anyway.

Sounds like your pots are dirty... a shot of cramolin or de-oxit may work, but the best thing to do is take it to a local tech who will clean or replace them........
