Sorry, but its' only a 7.1 AVR and nothing the manual "says" is going to change that, no matter how you interpret it.
I've just searched the manual and cant find a single reference to it being a true 9 channel amp
PDF version of the manual here: http://www.yamaha.ca/av/PDFs/Receive...863_Manual.pdf
adding zones allows you to remap your 7.1 channels, it doesn't add anymore internal amps.
It just the means you dont have to switch speaker wires around when SELECTING which 7 you want to use at any given time.
read the note at the bottom of this snip from the manual in regards to presence and back surrounds at the same time
My current RX-V3900 has the standard 7.1,
+ Front Presence, + Zone 2 + Zone 3 outputs
...does that make it a 13.1 AVR? obviously not.
The only 9.1 AVR Yamaha ever made was the Z-9...about 6+ years ago
and the only current model with more than 7.1 capability is the RX-Z11 with 11.2
(7.1 + Front Presence/Rear Presence) (140W x 7 + 50W x 4) and 4 Zone capable.
...Note every time you turn on an extra zone, you give up a pair of speakers in your main zone.
