Asus Essense Stx Audio Center Questions

So I just got the Essense stx and I've been tinkering with the program for it. I have a couple questions on how the equalizer/effects settings work. I usually play fps games like bf3 or arma and I want to tweak the low, mids, and highs so I hear less explosions and more footsteps and gunshots. If you know how to do any of this please help, thanks.
