Digital hash Groundloop

[Djinn]

Hi there
I currently hav a problem with digital hash low level noises from computer iv narrowed it down to my prophet rev2 and moog sub37 hash noise appears as soon as they are plugged into mains. Do you think balanced audio cables would help? What is the solution?

Have you tried the suggestions pertaining to power?

"Try changing your plug configurations for the synth and your laptop/computer, i.e. try unplugging your laptop from the wall and see if the problem still exists, and try plugging your DSI synth and the computer into the same outlet. You can also try using a surge protector/power conditioner, try powering your audio interface with a wall plug if it is bus powered normally."

Thanks for all the advice
I managed to correct a few issues i had within my setup (basically sloppy wireing) and have tweaked my pre amps a little more carefully and think its down to an acepetable level
Thanks again for the help
