Anyone know how to get 9.1 out of the Z9? This is my first high quality receiver and I had my room set up with the 9 speakers (including the two presence speakers and dual rears) that are hooked up to it. But the manual doesn't mention 9.1. I jave read elsewhere that the only way to get 9.1 was to be in Cinema mode (Sci-fi, Adventure, etc.) but those are listed in the manual as for 2 channel sound input, not multi-channel (DD 5.1) input. What settings would I need to get 9.1 from a DD 5.1 input?

Thank you in advance.
