Digital Clock Problem?

[mam]

Hello folks,

Recently moved my control room. Since then, I've developed a problem only when recording to the computer. Recording to the adats works fine. If I send a buss to the pc, I end up with gritty sounding, almost distorted tracks. If I normalize the track, it's a bus accident (uh, really nasty). I'm using a mackie 8-buss going to 2 adats & an Alesis AI-3 converter to the sound card. Logic Audio Gold with the Yamaha DSP Factory using C-Console as a control for the card. Everything USED to work great before the move. I've checked & rechecked all my connections. I THINK I have my wordclock set properly. I turn on the converter last. (A suggestion from Alesis).
If I leave the buss fader down & record a track I get "white noise" when normalized, If I have the fader up, I get white noise & god knows what else. I noticed that if I unplug one of the lightpipe connections while everything is on, I get a similar white noise. Anybody got any suggestions?

Thanks,
mam

I can only give you a few electrical ideas.
Is your computer outlet on a circuit with lighting,Microwave or refrigerator.
Did you check your internal connections on the computer after the move.
Do you think that your computer might be picking up EMF from somewhere. This includes Dimmers and Ballasts.
Do you think the grounds are OK.
My 2cents!

Thanks for the 2 cents Duck!

New control room is on it's own circuit. No dimmers or ballasts involved. Everything in the pc is tight. I wired all the outlets & I made sure all grounds were secure. Did some tracking Friday with no problem. Yesterday was a different story. Intermittent for sure.
The search is on!
