Weird noise when 57 is turned off

Drapol1 2:45 PM - 2 August, 2008
I can hear a weird "bzzzzzz" sound when I turn off my mixer. It happends when I connect it to my computer. It's annoying because when I don't use it I always have to mute the line in input on my PC. How to fix it?

is the noise coming from your mixer? speakers? CV's?

Don't use a ground lift plug, ground leads are there for a reason.
You should use an isolation transformer on the audio cable between the mixer and the laptop.

hmmm.. I'm not sure if I understand. Is it that thing that's call ground loop isolator or smth? I thought it might be the problem with my socket. The secket on my wall doesn't have that "wire" for ground. Hope u understand. Thx

It's always been good practice to turn off your sound system before turning off the mixer.

General rule of thumb:

Turn mixer on first and off last :)

If your socket has no ground connected you should have it checked by an electrician. The 57 is a metal box with a mains voltage connected to it, a fault inside the mixer could give you a nasty shock, or worse, kill you.

...and that would be bad
