Source material may be delivered via HDMI, or decoded toDolby Digitaland transmitted via S/P-DIF coaxial or optical digital audio.Dolby True HD Dolby True HD is an expansion of MLP Lossless™ audio, the same format used on DVD Audio discs. Dolby TrueHD adds the featuresfound in Dolby Digital, such as night mode settings, while delivering fully lossless audio that is a true reproduction of the studiomaster recording.DOLBY DIGITAL Available only with digital input sources encoded with Dolby Digital data. It provides up to five separate main audio channels and aspecial dedicated Low Frequency Effects channel.Dolby Digital EX Available when the receiver is configured for 6.1/7.1 channel operation, Dolby Digital EX is the latest version of Dolby Digital. Whenused with movies or other programs that have special encoding, Dolby Digital EX reproduces specially encoded soundtracks so thata full 6.1/7.1 soundfield is available. When the receiver is set for 6.1/7.1 operation and a Dolby Digital signal is present, the EX modeis automatically selected. Even if specific EX encoding is not available to provide the additional channel, the special algorithms willderive a 6.1/7.1 output.DTS-HD DTS-HD is a new high-definition audio format that complements the high-definition video found on HD-DVD and Blu-ray Discs. It istransmitted using a DTS core with high-resolution extensions. Even when only DTS 5.1 surround sound is desired (or available, if themultizone system is in use), the higher capacity of high-resolution discs serves up DTS at twice the bit rate used on DVD-Video discs.DTS-HD Master Audio DTS-HD Master Audio delivers bit-for-bit reproductions of the studio master recording in up to 7.1 channels, for an incredibly accurateperformance.DTS 5.1 When the speaker configuration is set for 5.1-channel operation, the DTS 5.1 mode is available when DVD, audio-only music orlaserdiscs encoded with DTS data are played. DTS 5.1 provides up to five separate main audio channels and a special dedicated low-frequency channel.DTS-ES 6.1 MatrixDTS-ES 6.1 DiscreteWhen the speaker configuration is set for 6.1/7.1 operation, playback of a DTS-encoded program source will automatically trigger theselection of one of the two DTS-ES modes. Newer discs with special DTS-ES discrete encoding will be decoded to provide six discrete,full-bandwidth channels plus a separate low-frequency channel. All other DTS discs will be decoded using the DTS-ES Matrix mode,which creates a 6.1-channel sound field from the original 5.1-channel soundtrack.DOLBY PRO LOGIC IIMOVIEMUSICDOLBY PRO LOGICGAMEDolby Pro Logic II is the latest version of Dolby Laboratory’s benchmark surround technology that decodes full-range, discrete left,center right, right surround and left surround channels from matrix surround encoded programs and conventional stereo sourceswhen an analog input or a digital input with PCM or Dolby Digital 2.0 recordings is in use. The Dolby Pro Logic II Movie mode isoptimized for movie soundtracks that are recorded with matrix surround, by creating separate center, rear left and rear right signals.while the Pro Logic II Music mode should be used with musical selections that are recorded with matrix surround or even with normalstereo mode, creating separate rear left and rear right signals in any case. The Pro Logic II mode creates compelling five-channelsurround sound from conventional stereo recordings. Game mode ensures that special effects are routed to the surround channels,while delivering their full impact using the subwoofer, thus fully immersing the game player in the universe of the video game.DOLBY PRO LOGIC IIxMOVIEMUSICGAMEDolby Pro Logic IIx is the latest extension of Dolby Pro Logic II technology that creates a discrete 6.1 and 7.1 sound field from matrixsurround or two-channel stereo sources in systems configured for surround back speakers. Movie, Music and Game versions of ProLogic IIx are available. Game mode ensures that special effects are routed to the surround channels, while delivering their full impactusing the subwoofer, thus fully immersing the game player in the universe of the video game.Logic 7 CinemaLogic 7 MusicLogic 7 EnhanceExclusive to Harman Kardon for AV receivers, Logic 7 is an advanced mode that extracts the maximum surround information fromeither surround-encoded programs or conventional stereo material. Depending on the number of speakers in use and the selectionmade in the Surround Select menu, the “5.1” versions of Logic 7 modes are available when the 5.1 option is chosen, whilethe “7.1” versions of Logic 7 produce a full sound field presentation, including back surround speakers when the “6.1/7.1” option ischosen. The Logic 7 C (or Cinema) mode should be used with any source that contains Dolby Surround or similar matrix encoding.Logic 7 C delivers increased center-channel intelligibility, and more accurate placement of sounds with fades and pans that are muchsmoother and more realistic than with former decoding techniques. The Logic 7 M or Music mode should be used with analog orPCM stereo sources. Logic 7 M enhances the listening experience by presenting a wider front soundstage and greater rear ambience.Both Logic 7 modes also direct low-frequency information to the subwoofer (if installed and configured) to deliver maximumbass impact. The Logic 7 E (or Enhance) mode is an extension of the Logic 7 modes that is primarily used with musical programsand is available with the 5.1 surround mode option selected only. Logic 7 E adds additional bass enhancement that circulates lowfrequencies in the 40Hz to 120Hz range to the front and surround speakers to deliver a less localized soundstage that appears broaderand wider than when the subwoofer is the sole source of bass energy.
