Looking for advise regarding which receiver I should purchase to handle the use case I want. I have a left/right set of speakers already installed in the ceiling of my family room. I have a second set of speakers installed outside on my patio. Both speakers run old style wire connections with the red/black combination. I'd like to have 1 receiver, where I can toggle the output from the receiver between the 2 sets of speakers. All the receivers I've seen that allow multi-room functionality expect one of the sets of speakers to run on HDMI or newer connection methods. Mine are all old school. Thoughts on which receiver would work?
