If you got that, you would not need the mixer.......unless you were recording with more than two mics at once time...but even still, the mixer really isn't the way to go IMO.

See my videos here as well as "mixers for recording" or even the budget limited starters.
Okay, but if we record with more than 2 mics, would it be possible to plug the mixer into that, and then plug that in the computer without losing quality?
