No sound outputs from the surround speaker,center speaker and subwoofer if the DVD disc hasno surround data.AbbrevationsL/R : Front speakersC : Center speakerSL/SR : Surround speakersSB : Surround Back speakerSubW : Sub woofer speakerThe relation between the selected surround mode and the input signalThe surround mode is selected with the surround mode buttons on SR5400/SR6400/PS5400 or the remote control unit. However, the sound you hear is subject to the relationship between the selected surround mode and input signal. That relationship is as follows;3The advantages of discrete multichannel systems over matrix are well known.But even in homes equipped for discrete multichannel, there remains a need for high-quality matrix decoding. This is because of the large library of matrix surround motion pictures available on disc and on VHS tape; and analog television broadcasts.The typical matrix decoder of today derives a center channel and a mono surround channel from two-channel matrix stereo material. It is better than a simple matrix in that it includes steering logic to improve separation, but because of its mono, band-limited surround it can be disappointing to users accustomed to discrete multichan-nel.Neo 6 offers several important improvements as follow,. Neo 6 provides up to six full-band channels of matrix decoding from stereo matrix material. Users with 6.1 and 5.1 systems will derive six and five separate channels, respectively, corresponding to the standard home-theater speaker layouts. Neo 6 technology allows various sound elements within a channel or channels to be steered separately, and in a way which follows naturally from the original presentation. Neo 6 offers a music mode to expand stereo nonmatrix recordings into the five- or six-channel layout, in a way which does not diminish the subtlety and integrity of the original stereo recording.DTS-ES Extended Surround is a new multi-channel digital signal format developed by Digital Theater Systems Inc. While offering high compatibility with the conventional DTS Digital Surround format, DTSES Extended Surround greatly improves the 360-degree sur-round impression and space expression thanks to further expanded surround signals. This format has been used professionally in movie theaters since 1999.In addition to the 5.1 surround channels (FL, FR, C, SL, SR and LFE), DTS-ES Extended Surround also offers the SB (Surround Back) channel for surround playback with a total of 6.1 channels. DTS-ES Extended Surround includes two signal formats with differ-ent surround signal recording methods, as DTS-ES Discrete 6.1 and DTSES Matrix 6.1.“DTS”, “DTS-ES Extended Surround” and “Neo:6” are trademarks of Digital Theater Systems, Inc.The stereo CD is a 16-bit medium with sampling at 44.1 kHz. Pro-fessional audio has been 20- or 24-bit for some time, and there is increasing interest in higher sampling rates both for recording and for delivery into the home. Greater bit depths provide extended dynamic range. Higher sampling rates allow wider frequency response and the use of anti-alias and reconstruction filters with more favorable aural characteristics.DTS 96/24 allows for 5.1channel sound tracks to be encoded at a rate of 96kHz/24bits on DVD-Video titles.When DVD-video appeared, it became possible to deliver 24-bit, 96 kHz audio into the home, but only in two channels, and with serious limitations on picture. This capability has had little use.DVD-audio allows 96/24 in six channels, but a new player is needed, and only analog outputs are provided, necessitating the use of the D/A converters and analog electronics provided in the player.DTS 96/24 offers the following:1.Sound quality transparent to the original 96/24 master.2.Full backward compatibility with all existing decoders. (Existing decoders will output a 48 kHz signal) 3.No new player required: DTS 96/24 can be carried on DVD-video, or in the video zone of DVD-audio, accessible to all DVD players. 4.96/24 5.1-channel sound with full-quality full-motion video, for music programs and motion picture soundtracks on DVD-video.2. TECHNICAL DESCRIPTIONDolby Digital identifies the use of Dolby Digital audio coding for such consumer formats as DVD and DTV. As with film sound, Dolby Digital can provide up to five full-range channels for left, center, and right screen channels, independent left and right surround channels, and a sixth ( “.1”) channel for low-frequency effects.Dolby Surround Pro Logic II is an improved matrix decoding tech-nology that provides better spatiality and directionality on Dolby Sur-round program
