Sorry about that. Right now one of my HDSP 8652 outputs is hooked to an ADAT AI-3. Not as nice as your RME converter but reasonable. I think I could test it if you could give me some clear instructions on how to do this quickly. I don't have enough time to figure it out by myself. IS it really as easy as connecting an output to an input? One question for you. Is the problem identical no matter what ADAT port you use on the HDSP 9652? Cheers, Mark
