Dolby Surround Pro Logic

Dolby Pro Logic is the four channel surround-sound system that is desinged to be played back on five speakers. Included in these five speakers are a center channel that produces all the on-screen sound, left and right front effect speakers that move with the action of the movie, and two rear surround speakers that both reproduce simutaniously the time-delayed mono signal which provides ambience and sound effects. This effect creates a movie theater like surround experience in the home.
