what I mean is that, I know that I need 11 channels (whether that be 11 right on the AVR or 9 on the AVR plus 2 on an external amp). What I am asking about is the software. Will the software let me configure these 11 channels to run in a 9.1 + zone 2 setup?
Looking at the manual, it doesn't seem like any of these receivers supports that in software even though all receivers support up tp 11 channels
As another example that I just found, the Denon x6700h has a page in the manual that explicitly talks about how to setup a 9.1 + zone 2 setup.
So, it's unclear to me whether the Marantz Cinema 50, Denon x3800h, or Onkyo RZ50 support a 9.1 + zone 2 configuration in software, evem though they all technically support 11 Channels
