It's worth checking out the Hammerfall AEB-8 I/O cards as well. They're cheap and they sound good. Not sure if you can have both an input and an output card connected to the 9652's internal ADAT connection. I just got this setup with the AEB-8 I only though, and it works great. As a long time Digi 888/24 user, I'm really impressed with Hammerfall. Jack
