After much search, and reading reviews and posts, etc I finally purchased a Sony STR-DA4ES. So far I like it. Although I an still using my old poineer speakers (CS-C9900), the sound is really good. The only -ve I have at this time is the manual. I wish it had more info, specially on using the remote. This brings me to my question. Can some one tell me how to setup the unit so that I can hear music on my deck speakers while watching a movie at the same time. I see that there is a A & B speaker switch, but I am not sure how to use it. I was told by the sales man the this receiver has such a capability without using another amp. Any help will be much appreciated.
