can audio be split to L & R channels after capture?

I am working in CS4 and don't use it that much. I am an FCP guy, but am using CS4 on this project. I captured DV with 2 channels of audio. One of the talent had a turtle neck and it was hard to place a lav mic. She was off axis a bit. All I need to do is bump up her audio a few db to match the db level of the male voice.

How do I manipulate L and R audio tracks in CS4? I am at a loss.
