I know I've read in the past about being able to "setup" your HT with software, a microphone, and a PC with decent audio card. I'll try to dig the article up and post if others don't already know.
With regards to receivers that 'interpolate' 5.1 to 7.1 I'm assuming I need to hook assuming I need to hook up all the speakers. If I'm in a smaller space right now as mentioned at the start of this thread - the 5.1 Epic Grand Master setup with VP150 and possibly larger sub will be plenty with extra room for the future room?
No use putting rear channels 4 feet apart?
