Can you adjust the draw weight on a 2011 pse brute?

I know on the details it says 60 & 70 lbs but I'm not sure if you can adjust it. The bow I'm shooting right now is 55lbs, I want to slowly move up to 70lbs but I can really make the jump from 55 to 70. So anyone with a 2011 pse brute, does it adjust from 60 to 70 or is it just a flat out 60lbs bow and a flat out 70lbs bow.
