I solved (created) my own problem. While running a profile for my studio, somehow the song file I was using in Studio One Pro got corrupted. The white intermittent noise I was hearing was in the song file I was mixing in two or three places. After finally realizing the "intermittent" noise was occurring in the same places, I zoomed in on the file and, sure enough, there was the white noise distortion. I deleted that file and imported the original virgin copy again. How crazy is that? Anyway, the new ARC 2 is a great upgrade. If you are having white noise problems, check the file you are working with. I can't explain it but it may have had something to do with having the recording program open while I ran the ARC 2 profile.
