need help! getting interference in my studio monitors!

[millenliam]

hey
new to this forum... but not new to recording... i've had a home setup for over 2 years now.

however, i've always had some slight interference in my speakers, but since i've moved into my university flat, the interference has got louder.

i am currently using a mac mini with an M-Audio firewire 410 interface with a pair of active Behringer truth B2031A studio monitors.

the interference i'm getting is like a humming sound with a little hissing and crackling, and when i move my mouse or the computer is doing something ( such as loading up logic express 7 or playing songs on itunes), the hissing/cracking gets louder. when i listen closely, it also sounds like there is a kind of pulse.
someone suggested that it could be an earth loop... could this be the case?

any other suggestions to what it could be and how i could solve my problem?

Yup. It sounds like some kind of ground loop to me. Your options? They make isolation transformer things and line conditioners. While they dont' always work perfectly, they help quite a bit. Sometimes they do work perfectly.

Check out this Furman Power Conditioner. There are probably cheaper versions, but this will point you in the right direction.
