it's a SEVEN channel receiver, period. It can do 5.1 plus two additional channels -- heights, rears, or wides. What is confusing is that Onkyo gives you 11 sets of binding posts; those extra two channels of processing come out of ONE of the three pairs of binding posts (labeled height/rear/wide) but ALSO out of the pre-outs for Surr.Back.
So whichever 6th/7th channel processing you are using, it will come out of the appropriate speaker posts and ALSO it will come out of the Surr.Back pre-outs.
You will never get it to have nine "unique" channels.

To reiterate, if you only have 7 or 9 physical speakers, and do not want to add more speakers to your room, (but still want height), stick with the other models, such as the 607 which has IIz height already built in.
I disagree with this -- the 607 has no option for "wide" channels and it doesn't have DSX. Why do you NEED to have all 11 speakers to take advantage of DSX? It's only a seven channel receiver, you can't use more than seven at a time! Even if I only had seven speakers I'd want to have the option for "5.1 + wide" arrangement using DSX.
