DTS Digital Surround™ was developed to replace the analog soundtracks of movies with a 6.1 channel digital sound track and is now rapidly gaining popularity in movie theaters around the world. DTS, Inc. has developed a home theater system so that you can enjoy the depth of sound and natural spatial representation of DTS Digital Surround™ in your home. This system produces practically distortion-free 6 channel sound (technically, front left and right, center, surround left and right and LFE 0.1 (subwoofer) channels for a total of 5.1 channels). This unit incorporates a DTS-ES decoder that enables 6.1 channel reproduction by adding the surround back channel to the existing 5.1 channel format.
