Easy to implement with standard Dolby equipment, Dolby Surround 7.1 expands the creative palette of sound design, providing filmmakers with more control over the exact placement of sounds within the theatre environment. The result: new opportunities for mixers and sound designers to create audio that takes the cinema experience to the next level.

Why Dolby

A partner to studios and exhibitors for 40 years, Dolby pioneered surround sound in the movies. Dolby Surround 7.1 represents our latest cinema innovation. Its four surround zones incorporate the Left Surround and Right Surround of Dolby Digital 5.1 while adding new Back Surround Left and Back Surround Right zones.

The fact that each of these surround zones is discrete means that mixers now have greater control over the placement of the details in their soundtracks. With Dolby Surround 7.1, the potential to unify the audio and visual components of a film for maximum impact is unprecedented.

Studios are mixing movies in Dolby Surround 7.1 today. For exhibitors who want to showcase this new format in their theatres, the process of outfitting a theatre for Dolby Surround 7.1 can be as simple as updating the firmware in the cinema processor and replacing an audio cable. Of course, Dolby Production Services technicians are in the field to work with theatre personnel to make the transition to Dolby Surround 7.1 as seamless as possible.
