Combines the front and rear signals so that you can enjoy a regen-
erated sound field which has comparatively more presence and a
more expansive feeling from the front 3 channels (front L, front R,
center speaker) than that of ordinary stereo regeneration.

m

A great number of movies made in recent times have the sound
track specially encoded with the Dolby Surround Mode (carrying
the [Dolby Stereo] or [Dolby Surround] trademark*).

The front speakers provide the dialogue and the normal stereo
effect, while the rear speakers reproduce the surround signals.
This position provides excellent results when watching television
programs, video software, video discs or video tapes of stereo tele-

vision broadcasts encoded with Dolby Surround. Dolby Stereo
films have dramatically changed the role of the movie-goer from
that of observer to that of participant. Clearer dialogue, richer
music, enveloping ambience and making high-fidelity, multi-
dimensional sound are essential parts of cinematic presentations.
Imagine recreating the same sort of audio-visual experience right
in your own home.
