Does anyone have an onkyo prsc 5509

I'm just a little stuck on when I set up the audyssey for 9.2 channels, why doesnt it read 9.2 channels when I hit the info button? Odviously meaning 9 speakers and 2 subs. It only reads 9.1. I was hopeing to find someone with the same unit, with a dual subs hooked up as well.
