I have a Presonus setup with an AudioBox USB and Studio One software, and was recently given the Fostex MR8 mkii unit.

With the Fostex's 8 channels, can I use it to route Skype calls (aux-minus), phone calls (with a digital hybrid and aux-minus), and other audio sources to the DAW?

I have the manual, but it is not very "user-friendly" when it comes to figuring out questions, as it assumes other uses, I guess.
