My concept, however, is different from Yamaha and similar products that have been sold to date. This product would contain the electronics to decode a full 7.1 HDMI signal and have the amps and speakers for the center channel and side/rear surround deflection only. It would output an analog signal for the left and right mains, which could then be input into a RR2150 or any other stereo receiver. It would also have an analog sub-in and sub out. If the Bar was decoding an HDMI signal it would take care of the full sub-out (with a setable cross-over), otherwise it would just route the sub-in to the sub-out.
