DTS™ 5.1 DTS produces 5 discrete (perfectly separated) sound channels and a dedicated LFE (Low Frequency Effects) subwoofer channel.
For this reason it is known as a 5.1 channel system (the .1 indicating the subwoofer channel that has limited frequency for just the low audio frequencies)
DTS has all the benefits of an all digital system in terms of clear sound without distortion and noise.
DTS is used in a variety of video/audio formats world wide including. DVD, Laserdisc, Computer Games, Radio and TV broadcasting.
DTS boasts a higher bitrate than its competing format Dolby Digital and therefore can provide higher sound quality (Due to there being less compression)
