MarkDann, For $64,000 I'll come setup the system and make it work for you and spring for lunch .. For free, I can tell you of some gear to check out on your own. At namm I spent some time at the ardvark booth talking with their rep. They make a box (can't remember the exact name now) that has rock solid clock as well as smpte inputs - mtc output - various clock outputs. AES was 1 of the clock outputs and they have a high quaity convertor to change it from AES to S/PDIF which the 001 can lock to. This will give you 1 box that takes care of sync for all your devices. Word clock to the BRC - S/PDIF to the 001 and it's getting it's positional reference from SMPTE and generating clock based on that SMPTE reference Also, there's the digital time piece which has S/PDIF outs (there is not a USB version currently). This seems to work okay but I'd take my chances with the ardsync box. Anyone else having the same problems locking adats to the 001? B Carter Digidesign
