Konichiwa,
You can buy something like an RME card that you install in your computer that will give AES and ADAT input and outputs. You then buy some cables and have them go directly into your Apogee. This is what I have running in my computer to my Rosetta 800 and it works great. Here is one of them.
RME: Hammerfall DSP 9652
