I have a Sony STR-DB1070 receiver with a subwoofer, a center speaker, and 4 other speakers. I also have two other speakers that I would like to connect, but I want them to be in the other room. For these two speakers in the other room, I would like to be able to play music on them using the receiver while the home theater system runs in the tv room. My receiver says that it supports second room capability, but I am not sure how to get it working. The only available speaker outlet I have is "Surround Back." I have a Monster Mult-Speaker Selector, and I thought maybe that would help. Thanks.
