I have this set up with a L/R/ Center speakers. I have them wired to the terminals on back for same, not using the surround sound teminal for L/R. When I stream Hulu/Netflix the center channel is active and sounds fine, but when I stream Pandora through Roku the center channel is also active and I am under the impression it should not be? When I play vinyl it does not energize the center channel. I have the sound set up in the yamaha menu to decode sound set on auto.
Any idea why the signal for pandora through roku is energizing the center channel?
Thanks.
Brian
