To show the movie with surround sound, a movie theater had to spend $85,000 for a special setup that included custom loudspeakers and required two projectors, one running the film and one track of audio plus a second one dedicated to four special audio tracks. Reaver ships are cobbled together and no two look alike,” explains Peristere. “We had to be creative.

ProLogic sends the center channel sound to an actual center speaker. If the in-phase signals from the left track AND the right track are identical, it sends the signal to the center channel. When the pickup in the projector reads the optical tracks, it decodes this signal as surround sound and sends it to the rear and side speakers in the theater. Many theaters offered surround sound as magnetic-based sound became popular, allowing four or even six channels of sound. The key difference in Surround and ProLogic is the center channel. It is interesting to note that Dolby Surround and Dolby ProLogic are the home versions of Dolby Stereo. A Dolby Surround system uses the right and left speakers to create a phantom center speaker.
