Hello all, I have a Pioneer VSX-LX302 that I am trying to figure out if I can use it in our theater that has a 9.2 speaker setup. I'm left with a set of surround speakers to connect. We just upgraded our projector to a 4K and our old Denon does not have the ability to support it. Is there a work a round for the 2nd set of surrounds or are we going to have to buy a better receiver? Thanks for any suggestions.
