34 ENAmbience effectsDolby DigitalThe Dolby Digital surround format lets you enjoy up to 5.1 channelsof digital surround sound from Dolby Digital program sources (such asLaserdisc or DVD software marked ). Compared with previ-ous Dolby surround, Dolby Digital provides even better sound quality,greater spatial accuracy, and improved dynamic range.Dolby Digital EXDolby Digital EX is an extension of Dolby Digital technology, DolbyDigital EX creates six full-bandwidth output channels from 6.1-chan-nel sources. This is done using a matrix decoder that derives threesurround channels from the two in the original recording.This is achieved by using three different surround signals, surroundleft, surround right, and surround back, each driving its own array ofspeakers. Think of it as adding a center channel for the rear speakers,which give more diffuse and natural surround effect, even if youwanted the ability to completely encircle the audience with sound,positioning sound effects exactly where they would be heard in reallife. For best results, Dolby Digital EX should be used with moviesoundtracks recorded with Dolby Digital Surround EX which containa digital flag that will automatically activate this feature. However, fortitles released prior to late 2001, this feature has to be activatedmanually.Although Dolby Digital soundtracks incorporate a separate lowfrequency channel, connecting a subwoofer will also improve deepbass performance in the other surround modes.The indication “LFE” appears in the display when a signal is beinginput for this channel.Dolby Pro Logic IIx and Dolby Pro Logic IIDolby Pro Logic II was designed specifically to provide a new senseof spatiality, directionality and articulation of sounds from DolbySurround encoded sources (such as video and Laserdisc softwaremarked ). This is achieved with an intelligent, built-infeedback logic design, a matrix surround decoding and the decodingof stereo, full bandwidth surround outputs.Dolby Pro Logic IIx enhanced Dolby Pro Logic II’s features.It creates 6.1 channel and 7.1 channel surround sound from stereo or5.1 channel signals. This feature provides you an astonishing ambi-ence effect which makes you feel you are surrounded by naturalsound. Especially 7.1 channel surround sound can produce real backsound from Surround Back speakers.The Pro Logic IIx modes programmed into this model are “Movie”,“Music” and “Game”. The Pro Logic II modes programmed into thismodel are “Movie”, “Music”, “Game” and “Pro Logic”. The “Movie”mode has preset characteristics to produce a calibrated, high-levelsurround sound playback while the “Music” mode has user-adjust-able characteristics to offer the three optional controls, like “Dimen-sion”, “Center Width” and “Panorama” modes to allow optimizationof the soundfields as desired. The “Dimension” control allows theuser to gradually adjust the soundfield either towards the front ortowards the rear; the “Center Width” control allows various adjust-ment of the left-center-right speakers’ balance; the “Panorama”mode extends the front stereo image to include the surround speak-ers for an exciting “wraparound” effect with side wall imaging.The “Game” mode provides surrounded and exciting sound whenyou enjoy game or TV. Especially in Pro Logic IIx “Game” mode, basesound not only from Front and Center but also from Surround channelis added to Subwoofer. This provides ever more dynamic surroundeffects.DTSThe DTS multi-channel audio format is available on CD, LD and DVDsoftware. DTS is a strictly digital format and cannot be decoded insidemost CD, LD or DVD players. For this reason, if you attempt to listento DTS encoded software through the analog output of your new CD,LD or DVD player, you will experience digital noise in most cases. Thisnoise can be quite loud if the analog output is connected directly to ahigh power amplification system. Proper measures for playing thedigital output as described below should be taken to avoid thissituation. To enjoy DTS Digital Surround playback, an external 5.1channel DTS Digital Surround decoder system or an amplifier with abuilt-in DTS Digital Surround decoder must be connected to the digitaloutput (S/P DIF, AES/EBU or TosLink) of a CD, LD or DVD player.All models are incorporated with the DTS decoder.DTS-ESDTS-ES (Digital Theater System-Extended Surround) presents 6.1channels surround system with additional Surround Back channelwhich evolved from the conventional 5.1 channels surround system.DTS-ES format that was recorded in DVD, CD or LD comprises of twomodes. DTS-ES Discrete 6.1 produces the discrete surround backwhich is completely independent and DTS-ES Matrix 6.1 producesthe surround back which synthesised within the left and right sur-round channels using matrix technology. DTS-ES has perfect compat-ibility with the conventional 5.1 channels surround system. 6.1channels surround with an additional surround back presents a morenatural presence and surround effects by increasing the impressionof the sound image from back. Programs which are recorded usingDTS-ES technology consist of information flags which will be able tocontrol the Discrete and Matrix mode. Thus, it can automaticallyselect the best matched mode.Neo:6Neo:6 is a new technology which was developed by DTS. It canproduce high grade 6 channels surround with an astonishing fidelityfrom 2 channels content. Neo:6 has 2 modes, “Cinema” mode is formovie playback and “Music” mode is for music playback.DTS 96/24DTS 96/24 made it possible to achieve a wide frequency range of over40 kHz by increasing the sampling frequency to 96 or 88.2 kHz.Moreover, DTS 96/24’s ability of 24 bit resolution offers the samefrequency band and dynamic range as 96 kHz/24 bit PCM.DTS 96/24 is, as with conventional DTS Surround, compatible withmulti-channels. Therefore, sources recorded using DTS 96/24 tech-nologies can be played in high sampling frequency, multichannelaudio with ordinary DVDs and CDs.DTS has a “.1” or “LFE” channel.The indication “LFE” appears in the display when a signal is beinginput for this channel.Dolby Virtual SpeakerThe Dolby Virtual Speaker features a virtual surround sound field.This implements an effect as if there are multiple speakers in thelistening room.Dolby HeadphoneWhen headphones are used in music listening, the audio of the left(or right) channel reaches only the left (or right) ear so the listenercannot feel the presence of acoustic images on the front.The Dolby Headphone simulates a virtual room and include itsacoustic characteristics in the left and right headphone signals. As aresult, the listener can hear the same components as in speakerlistening through the left and right years and therefore feel as if thesound source is located on the front of the listener.Because of the same processing in "Pro Logic II Movie mode withDolby Headphone" and "Pro Logic II Game mode with Dolby Head-phone", their respective effectiveness is the same.NoteLFE = Low Frequency Effects. This channel delivers separate non-directional bass signals to the subwoofer for more dynamic deepbass sound effects.DSP modeThe DSP mode lets you add the atmosphere of a live concert or hallto almost any type of program source. The way a sound is heard in anactual environment depends on a variety of different factors. One ofthe most important is reverberation (the act of decaying elements ofsound echoing in various places).The DSP modes produce the feeling of presence by using the DSP tocreate reverberation, without spoiling the sound quality of the originalsignal. These modes are particularly effective when used with stereoprogram sources, like CD, television, and FM radio. You might enjoytrying the Arena, Jazz Club, Theater, Stadium or Disco mode the nexttime you watch a concert or sporting event!
