Calling All Electrical Engineers -- Ground Loop Hum Question
Posted: Sun Nov 06, 2005 9:09 am
Alright, so I've been dealing with this annoying hum from my monitors for a while now that just got a lot worse with my new power amp. The manual said there might be some ground problems, and to get a line conditioner or something. So I called up Guitar Center, and they told me I could first try breaking the ground. So I got a $0.99 3-prong to 2-prong adapter and voila! No more hum.
My question is this: that's obviously somehow dangerous. How and why is it dangerous? What protection does the ground provide, anyway? What's gonna happen if I leave my power amp plugged into the surge protector with no ground connection? Is there something I can buy that does the same thing as my $0.99 adapter but is perfectly safe?
Is this what I want?
