I use my 990 for 2 channel music only (with a sub woofer). Two front speakers are connected to the 990/7500. There is no center and surround speakers connected. In the "Speaker Size" menu, I set "Front" to "Large" and "Surrounds" to "none". But there is no "none" selection in the menu for the center channel. It forces me to chose either "large" or "small". I am wondering how can I make "none" selection for all surrounds and the center channels.

I do have installed with success the software updates released early this year. A couple of other people asked the same question, but there is no answer yet. Can some of you experts advise me on this issue? Thanks a million!!!
