Dolby Surround Dolby Digital Dolby Digital is a multichannel digital signal format developed by Dolby Laboratories. A total of 5.1-channels are played: 3 front channels ("FL" , "FR" and "C"), 2 surround channels ("SL" and "SR") and the "LFE" channel for low frequencies. Because of this, there is no crosstalk between channels and a realistic sound field with a "three-dimensional" feeling (sense of distance, movement and positioning) is achieved. A real, overpowering sense of presence is achieved when playing movie sources in AV rooms as well. Dolby Pro Logic g Dolby Pro Logic g is a matrix decoding technology developed by Dolby Laboratories. Regular music such as that on CDs is encoded into 5-channels to achieve an excellent surround effect. The surround channel signals are converted into stereo and full band signals (with a frequency response of 20 Hz to 20 kHz or greater) to create a "three-dimensional" sound image offering a rich sense of presence for all stereo sources. Dolby Pro Logic gx Dolby Pro Logic gx is a further improved version of the Dolby Pro Logic g matrix decoding technology. Audio signals recorded in 2-channels are decoded to achieve a natural sound with up to 7.1-channels. There are 3 modes: "Music" suited for playing music, "Cinema" suited for playing movies, and "Game" which is optimized for playing games. b Sources recorded in Dolby Surround Sources recorded in Dolby Surround are indicated with the following logo marks.
