35、mote 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;3DTS was introduced in 1994 to provide 5.1 channels of discrete digital audio into home theater systems.DTS brings you premium quality di

36、screte multichannel digital sound to both movies and music.DTS is a multichannel sound system designed to create full range digital sound reproduction.The no compromise DTS digital process sets the standard of quality for cinema sound by delivering an exact copy of the studio master recordings to ne

37、ighborhood and home theaters.Now, every moviegoer can hear the sound exactly as the moviemaker intended.DTS can be enjoyed in the home for either movies or music on of DVDs, LDs, and CDs.“DTS” and “DTS Digital Surround” are registered trademarks of Digital Theater Systems, Inc.The advantages of disc

38、rete 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 broadcast

39、s.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 us

40、ers accustomed to discrete multichannel.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 fi ve separate channels, respectively, corresponding to the st

41、andard 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 fi ve- or six-channe

42、l layout, in a way which does not diminish the subtlety and integrity of the original stereo recording.SR4001-5001U DFU_ENG.indb 206.6.21 4:21:20 PMDTS-ES Extended Surround is a new multichannel digital signal format developed by Digital Theater Systems Inc. While offering high compatibility with th

43、e conventional DTS Digital Surround format, DTS-ES Extended Surround greatly improves the 360-degree surround 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 (F

44、L, 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 different surround signal recording methods, as DTS-ES Discrete 6.1 and DTS-ES Matrix 6.1.“DTS”

Professional 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. Grea

46、ter bit depths provide extended dynamic range. Higher sampling rates allow wider frequency response and the use of anti-alias and reconstruction fi lters 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

47、.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,

48、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)SR4001-5001U DFU
