Hello.
I have a problem with EMI in my studio, it seems that it gets in the recorded audio signal, although I use very quality cables in my studio which are mogami finest cables, I still cant get rid of it, and I have noticed that whenever I turn off my computer screens the interference is gone.
Maybe it is grom my graphics but I dont think so.
Any sugesstions?
Thank You.

Are you using a dedicated circuit for your audio gear?. Make sure your gear is all on one circuit, including the comuter. It's not that unusal that outlets within one room are on different breakers at the main panel. The circuit you're on now probably shares grounding with other service, ie; lighting. Are there any dimmers in the house? They're a common source of noise. A power conditioner (like a Furman) will help.

This means that your monitors are not shielded. Most monitors were not ment to be placed right next to a computer screen. You'll either have to move your screen away from your monitors, or purchased "shielded" monitors. Most companies shield their monitors for this exact reason. what kind are you using right now?

Yep, get a Flat screen.

If you sit in front of a CRT with a Stratocaster you will certainly know what a CRT can do to the noise-floor.

Also, CRT's can effect any part of a circuit that is unshielded. Even if you have one little piece of a connection not protected, you're going to get EMI.

EMI is very tricky stuff to contend with. I keep around a few sheets of copper shielding and Mu-Metal and have used both to tape over single coil pick-ups to physically shield them.

Good luck and buy a flat-screen.
