25 ENENGLISHDolby DigitalThe Dolby Digital surround format lets you enjoy up to 5.1 channelsof digital surround sound from Dolby Digital program sources (suchas Laserdisc or DVD software marked ). Compared withprevious Dolby surround, Dolby Digital provides even better soundquality, greater spatial accuracy, and improved dynamic range.Although a full set of speakers (front left, right, and center, surroundleft and right, and a subwoofer) is required for true 5.1 channel DolbyDigital surround sound, this receiver lets you enjoy Dolby Digital (andDolby Surround) program sources, even if you connect only the frontspeakers.Dolby Digital EXDolby Digital EX is an extension of Dolby Digital technology, DolbyDigital EX creates six full-bandwidth output channels from 6.1-channel sources. This is done using a matrix decoder that derivesthree surround 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 a full set of speakers (front left, right, and center, surroundleft and right, surround back and a subwoofer) is required for true 6.1channel Dolby Digital Surround EX sound, this receiver lets you enjoyDolby Digital (and Dolby Surround) program sources, even if youconnect only the front speakers.Although only 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 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. The PRO LOGIC II modesprogrammed into this receiver are “MOVIE”, “MUSIC” and “PROLOGIC”. The “MOVIE” mode of the PRO LOGIC II has presetcharacteristics to produce a calibrated, high-level surround soundplayback while the “MUSIC” mode has user-adjustable characteristicsto offer the three optional controls, like “Dimension”, “CenterWidth” and “Panorama” modes to allow optimization of thesoundfields as desired. The “Dimension” control allows the user togradually adjust the soundfield either towards the front or towardsthe rear; the “Center Width” control allows various adjustment of theleft-center-right speakers’ balance; the “Panorama” mode extendsthe front stereo image to include the surround speakers for anexciting “wraparound” effect with side wall imaging.Ambience effectsDVD 6-channel modeUsing a DVD player or the like equipped with six (5.1) output channelsand the receiver, you can enjoy multi-channel encoded DVD sourcematerial in all its splendor. Since the source signals are digital andeach channel is input independently, the resulting sound quality,sense of spaciousness, and dynamic range are superb.The indication “LFE” appears in the display during DVD 6-channelmode selection. ¢DSP modeThe DSP mode lets you add the atmosphere of a live concert or hallto almost any type of program source. These modes are particularlyeffective when used with stereo program sources, like CD, television,and FM radio. You might enjoy trying the ARENA, JAZZ CLUB,THEATER, STADIUM or DISCO mode the next time you watch aconcert or sporting event!What's DSP?DSP stands for Digital Signal Processor.The way a sound is heard in an actual environment depends on avariety of different factors. One of the most important is reverberation(the act of decaying elements of sound 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.DTS modeThe DTS multi-channel audio format is available on CD, LD and DVDsoftware. DTS is a strictly digital format and cannot be decodedinside most CD, LD or DVD players. For this reason, if you attemptto listen to DTS encoded software through the analog output of yournew CD, LD or DVD player, you will experience digital noise in mostcases. This noise can be quite loud if the analog output is connecteddirectly to a high power amplification system. Proper measures forplaying the digital output as described below should be taken toavoid this situation. To enjoy DTS Digital Surround playback, anexternal 5.1 channel DTS Digital Surround decoder system or anamplifier with a built-in DTS Digital Surround decoder must beconnected to the digital output (S/P DIF, AES/EBU or TosLink) of aCD, LD or DVD player.All models are incorporated with the DTS decoder.DTS has a .1 or LFE channel.The indication “LFE” appears in the display when a signal is beinginput for this channel. ¢
