I have an Onkyo NR717 and I'm looking to wire it for both 7.1 home theater use and powered Zone 2 and 3 in other rooms. I'd like to install physical switches that will allow me to either use Powered Zone 2 and 3 for music or the surround speakers for watching movies. My thinking is that when I want to watch a movie I can just flip two switches to get the full 7.1 experience, then flip the switches back when I'm done. Basically, I'll have a single speaker wire coming from my Front Wide/Zone 2 R and L that goes into a switch. One output of the switch will lead to the surround speakers, the other to the Zone 2 speakers.
I just want to verify that I'm not going to be doing any damage to the receiver itself with this setup.
