MC, thanks for your reply... I do understand the ADAT sync.. and thanks for bring that up. I suspect that the way of syncing the audio AISO is thought the optical cables. correct. So, by adding the RayDat card I'd just have to take the ins and outs of the Sony DMX R-100 directly to the two cards the first on 1-8 and the other card would be 9-24 channels.
I"m thinking I'd use the ins and outs and channels at unity gain and the mic pre's on the board for input levels. How do you think latency will be? I want to use my board because I can also use my outboard tube compressors on the input of the Sony.. but I am guessing that may add some latency (delay) in the channel..
We use Cubase (right now it's 6.5) but we have upgraded to 7.0 and will install the upgrade at the same time I configure the new card.
One last question (for now) Would there be any advantage to use a Digiface external box and interface card rather than a Raydat card?
I do have a Focusriite Safire Pro 40 and Octo-prees.. but my thoughts are that the preamp s in the Sony and the A/D converter would be a warmer sound over the Focusrite set up.. but I guess I just need to give it a try..
I will comment that I really like the AIO card, it seems very clean and versatile.
