        Four Surround Zones

        One of the innovations of Dolby Surround 7.1 is the creation of four distinct surround zones in the theatre. These surround zones provide filmmakers with greater control over the exact placement of each detail in their soundtracks.

        The orchestration possibilities that Dolby Surround 7.1 introduces allow mixers and sound designers to more accurately match their audio to the visuals onscreen. This means more depth and greater realism for you at the movies.

        In addition to improving the side-to-side panning of sounds and sound localization, Dolby Surround 7.1 enhances audio definition, so you hear individual sounds more clearly and distinctly. It also widens the listening "sweet spot"—in other words, the full power of Dolby Surround 7.1 is not limited to a handful of seats in the center of the theatre.
