How do I input my SD card recording (from my AR8) into StudioLive to see all the tracks?

I need to know the right way to take what I recorded on my sd card (on the AR8) and upload it to StudioLive so that I can see all 3 inputs as separate tracks. I don't even know if the sd card records from the mixer with each chael as a separate track (so that I can have isolation and fix things in post production) or if it just ends up being one track...a straight mix from my recording. Thanks so much.
