As soon as i connect any of my pres into my soundcard, i get some strange noise, almost like oscillation, and also some buzz/hum like sound.
My soundcard is inside the computer, which could explain the interferance to some degree, but its quite much, and very annoying.
I have unbalanced inputs also, which certainly doesnt help.
When i unplugged the SMPS supply for the external usb harddrive i was using, some of the noise went away, but not all.
Is it possible i will get rid of more of that pesky noise if i try another, better computer PSU as well?
I have a cheap SMPS style psu in my computer.
Any other ideas or things i can try to get the noise between my pres and computer down some more?
The transformer balanced units are dead quiet once i plug them into my external 2ch AD/DA box, which also has unbalanced ins. But the green still makes some noise, so im guessing that unit might have other issues as well.
