Premiere Pro CS 5.5 Audio Tracks

Hi! I´m new to Premiere Pro, I come from a FCP7 Background.

When I import a clip with audio channels 1 and 2 Premiere Pro assign those channels to audio tracks 4 and 5 in my timeline, I dragged the tracks to audio 1 and 2 but nothing happens, every time does that, could any body give me some tip?

Thank´s in advance!
