A separate input for each track, Akai EIE USB Mixer

I have searched for this and am having no luck finding an answer. I am recording on an Akai Pro EIE USB mixer with four mics going into four inputs. I use Pro Tools in the past, but I use the M-Powered version which will work with only M-Audio devices, so I am using audacity with my new mixer. In Pro Tools I can change inputs so that each mic records on a separate track. I understand that Pro Tools will be more robust that audacity; however, I can no figure how to adjust inputs for my track so that each mic records on a separate track. I have looked through the tutorial, FAQs, etc and for the life of me I can not find how to do this? Can it be done and if so, how? With thanks in advance.
