This is done using a matrix decoder that derives threesurround channels from the two in the original recording.This is achieved by using three different surround signals, LeftSurround, Right Surround, and Back Surround, each driving its ownarray of speakers. Think of it as adding a center channel for the rearspeakers, which give more diffuse and natural surround effect, evenif you wanted the ability to completely encircle the audience withsound, positioning sound effects exactly where they would be heardin real life.NoteFor best results, Dolby Digital EX should be used with moviesoundtracks recorded with Dolby Digital Surround EX which containa digital flag that will automatically activate this feature. However, fortitles released prior to late 2001, this feature has to be activatedmanually.This model lets you enjoy Dolby Digital (and Dolby Surround) programsources, even if you connect only the Front Speakers.
