The Pioneer VSX-451 Stereo Receiver has 80 watts per channel and Dolby Pro Logic Surround Sound. As we demonstrate in the video, the receiver is impressively able to "extract" (or decode) a surround signal from a standard analog stereo track. (This was very effective for those of us who had purchased a HiFi VCR and were just getting into home theater in the early 1990s.) Of course, this "matrix surround" technology is all now obsolete since the surround systems we use today (like Dolby Digital or DTS) support multiple independent signals for each channel.
