Hi,

I wonder if anyone could give me a little advice?

Firstly, I'm running a G4 based studio from my bedroom, I noticed a hum coming through my speakers (active reveals) which seems to have increased recently, I have narrowed it down to the computer, but it doesn't seem to be the soundcard as when I turn the soundcard off it still occurs - it also happens whilst the mac is booting so I'm guessing that it is an earthing problem, does anyone have any ideas as to how to get rid of it / reduce it? There was also a spate about two weeks ago where my computer was acting very peculiarly and made a lot of noise (i think the fan) and wouldn't boot - although I'm unsure if this has anything to do with it.
There are about 15 plugs all running off one socket so I thought this was the problem but when I plugged in just the mixer with speakers and mac it still happened so I just don't know... help! lol

I don't know whether it's one of the componants making the noise or a earth problem or the fact that the plugs are together etc but with the latter I've tried separately so unsure - anyone have any similar experiences - any solutions? Would a electricity stabiliser (or whatever they're called) fix it?

Many thanks to those who reply!
 
Problem solved!!!

Hello again,

In a moment of genius (or luck!) I found out that the problem was caused by the break out box from the soundcard being on or anywhere near the computer monitor! I have moved it away and the hum has gone!!!
It's daft that something so simple was causing me so many problems!
But anyway, hopefully others that experience the same will read this and save a lot of time!

Great site - well done!
