Hey guys and gals, I am working on a project for Science where I record me and a friend playing some (science) songs, and I've just got a quick question: I am planning on recording on my MacBook C2D. Is the input jack on the side mono or stereo? I ask because basically our set-up is two guitar amps close-miked and one vocal unamped, and this is all being fed into a cheap little mixer. Then, I have the output (a 1/4" mono plug) going into the computer, which necessitates an adapter for this 1/4" mono to the MacBook's input. Thanks!
