4200X as a pseudo 11.x AVR?
I have a question specific to the 4200X, and your experience with 9.x and 11.x setups can hopefully offer a definitive answer.
The 4200X is marketed as a 9.2 AVR.
My question is, if one is using a separate 7-channel power amp (for the fronts, sides, and rears, plus center), and only using two of the output channels on the 4200X to drive front Atmos speakers:
What would happen if two additional side Atmos speakers are connected, driven by two more of the available amp channels on the 4200X?
Are the channel assignments limited to a fixed choice of 9 speakers, OR does the AVR dynamically choose amongst the available 11 speakers as to which 9 a signal is sent to, based on the input information , OR does the AVR really have 11 channels of pre-amp processing, and all 11 speakers will be driven, based on the input signal?
Thanks for any insight you can provide.
