I'll be blunt and just ask it.

Would i need a power amp if i was using a mixer to record into a USB Interface. Example;

Run say 5 instrument inputs into a Beheringer Eurorack, and then using the Left and Right output of the Eurorack into the Digidesign Mbox, and then have them panned out when recording.

Would that work?
No, but you'll need to plug the Eurorack in. If you haven't bought the Mbox yet, I suggest getting a Firewire interface (if you want Pro tools look into M Audio's offerings).
