Contents Connections Playback o Dolby Dolby Digital Dolby Digital is a multi-channel 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 frequency effects. 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. This delivers a thrilling surround sound experience in the home. Dolby Digital Plus Dolby Digital Plus is an improved Dolby Digital signal format that is compatible with up to 7.1-channels of discrete digital sound and also improves sound quality thanks to extra data bit rate performance. It is upwardly compatible with conventional Dolby Digital, so it offers greater flexibility in response to the source signal and the conditions of the playback device. Settings Tips Appendix Dolby Digital EX Dolby Digital EX is a 6.1-channel surround format from Dolby Laboratories that allows users to enjoy in their homes the "Dolby Digital Surround EX" audio format jointly developed by Dolby Laboratories and Lucasfilm. The 6.1-channels of sound, including surround back channel, provide improved sound positioning and expansion of the surround sound field. 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 three modes: "Music" suited for playing music, "Cinema" suited for playing movies, and "Game" which is optimized for playing games. Front panel Display Rear panel 255 Remote Index
