Seeking the best home-theater surround sound experience? This receiver and your TV or HDTV are the core of what could be a whole new meaning of home entertainment. Built-in decoding for all the latest and greatest sound formats surrounds you with up to 7.1 separate channels of digital sound that analog systems can't match. Suddenly, movies have the same excitement and impact as in the theater. Bass is stronger and closer to the director's original artistic intent. And now, with 39 DSP modes for creating soundfields (such as Jazz, Rock Concert, Theater, etc.) and decoding processes such as Dolby Digital EX, DTS ES, and DTS neo:6, this receiver has the technology to decode tracks that provide additional rear surround sound. This brings the home theater experience even closer to what the director was looking to achieve when the movie was originally mastered.
