The DTS-ES Extended Surround decoder provides exhibitors with added dramatic surround effects. Designed to take advantage of the latest innovations in surround sound formats, Extended Surround/ES technology allows filmmakers to dazzle audiences with sound that envelops them from the rear and dramatically improves localization.

An increasing number of film directors are using ES Surround's additional rear channel, which is routed to an array of speakers along the back wall of the auditorium. This extra back channel is matrix-encoded into the left and right surround channels, much as a center front channel in optical formats is matrix-encoded within the L and R channels. Providing a fully immersive and engrossing cinematic experience, sound effects and other material can literally sweep around an audience even seeming to fly over them through the use of left, right and center surround loudspeaker channels.
