Easy way to balance levels

I have a mono mix with two people talking but the diff in levels between the two people is on the order of 24dBs. It doesn't have to be perfect, I need their levels to be closer to each other. I realize I could go in and raise the level at each section of the low speaker, but I need a quick and dirty way to do it. Anyone have an idea?

I tried a PeakLimiter, followed by an Amplitude Gain, however, it didn't quite work because I can't figure out how to make the gain happen after the limiter. I hope I'm making sense. This is probably an instance of just not knowing exactly how to work well within Soundtrack.

Thanks
