One thing that's essential for me in this setup is the ability of the A/D box to sync to external clock while using the analog inputs. This is so that I can use the Rosetta as the master clock (it has no clock input so it must be the master). The AI-3 does this through ADAT lightpipe - you run lightpipes to and from the 001, and then the AI-3 will sync to the 001. The Digimax has only a word clock input. This happens to work with the Rosetta, since it has a word clock (BNC jack) out. But if you were trying to use something without word clock out (like a DAT player for inputs 17-18, for example), you would be out of luck. Do you know how the Aard handles external clock? Jeff D.
