I'm planning to skip the proprietary digidesign I/Os and go in for Apogee or PrismSound. I figured that I need max. about 16 channels of AD. but for monitoring I may need only two channels of DA or may even stick to the DA of the Yamaha DM 2000. However, I'm confused on how to get digital outs from Pro Tools to my mixer. The Apogee AD-16X has an HD card to connect directly to PT, but what do I use to get the signal on the board? Will I need to incorporate something like the Dream ADA-8 or Rosetta 800 with HD card connectivity? But then I'll be limited to getting only 8 channels digital through one of those units. (I'd like to do most of my mixing using hardware and have ruled out a control surface). Please help!
