It provides up to five separate main audio channels anda special 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. When used withmovies or other programs that have special encoding, Dolby Digital EX reproduces specially encoded soundtracks so that a full 6.1/7.1 soundfield is available. Even if a source does not contain specific EX encoding, the special algorithms may be used to derive a 6.1/7.1 output.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 or laser discs encodedwith 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 Matrix When the speaker configuration is set for 6.1/7.1 operation, playback of a DTS-encoded program source will automatically trigger the selectionDTS-ES 6.1 Discrete of one of the two DTS-ES modes. Newer discs with special DTS-ES discrete encoding will be decoded to provide six discrete, full-bandwidthchannels plus a separate low-frequency channel. All other DTS discs will be decoded using the DTS-ES Matrix mode, which creates a 6.1-channelsound field from the original 5.1-channel soundtrack.Dolby Pro Logic II Dolby Pro Logic II decodes full-range, discrete, left, center right, right surround and left surround channels from either matrix surround-encodedMovie programs and conventional stereo sources when an analog input is in use. The Dolby Pro Logic II Movie mode is optimized for movie soundtracks,Music while the Pro Logic II Music mode should be used with musical selections. The Pro Logic II Game mode is designed to enhance the soundtrackGame of video games from either dedicated consoles or computers.The Pro Logic mode re-creates original Pro Logic processing for thosePro Logic who prefer that presentation.Dolby Pro Logic IIx Dolby Pro Logic IIx is the latest extension of Dolby Laboratory’s benchmark surround technology that creates a discrete 7.1 sound field fromMovie matrix surround or two-channel stereo sources when your system is configured for surround back speakers. Movie, Music and Game versions areMusic available that customize the processing to the type of source in use. These modes may also be used to add surround back channels to 5.1 digitalGame soundtracks.Logic 7 Cinema Exclusive to Harman Kardon for A/V receivers, Logic 7 is an advanced mode that extracts the maximum surround information from eitherLogic 7 Music surround-encoded programs or conventional stereo material. When your system has been configured for use with Surround Back speakersLogic 7 Enhance (see page 41), you may choose between either 7.1 or 5.1 versions of the Logic 7 modes, while only the 5.1 versions are available whenthere are no Surround Back Speakers. The Logic 7 C (or Cinema) mode should be used with any source that contains Dolby Surround or similarmatrix encoding. Logic 7 C delivers for increased center channel intelligibility, and more accurate placement of sounds with fades and pans. TheLogic 7 M, or music mode, enhances the listening experience by presenting a wider front soundstage and greater rear ambience. Both Logic 7modes also direct low-frequency information to the subwoofer (if installed and configured) to deliver maximum bass impact. Logic 7 addsadditional bass enhancement that circulates low frequencies in the 40Hz to 120Hz range to the front and surround speakers to deliver a lesslocalized soundstage that appears broader and wider than when the subwoofer is the sole source of bass energy. Logic 7/7 may also be used to addsurround back channels to many 5.1 digital soundtracks.DTS Neo:6 Cinema These two modes are available when any analog source is playing to create a three-channel, five-channel or six-channel surround presentation fromDTS Neo:6 Music conventional Matrix-encoded and traditional Stereo sources. Select the Cinema version of Neo:6 when a program with any type of analog Matrixsurround encoding is present. Select the Music version of Neo:6 for optimal processing when a non-encoded, two-channel stereo program isbeing played.Theater The Theater mode creates a sound field that resembles the acoustic feeling of a standard live performance theater.Hall 1, Hall 2 The two Hall modes create sound fields that resemble a small- (Hall 1) or medium-sized (Hall 2) concert hall.Dolby Virtual Speaker Dolby Virtual Speaker technology uses a next-generation advanced algorithm to reproduce the dynamics and surround sound effects of a preciselyReference placed 5.1-channel speaker system using only front left and right speakers. In the Reference mode, the apparent width of the sound across the frontWide image is defined by the distance between the two speakers. The Wide mode provides a wider, more spacious front image when the two speakers areclose together. Depending on the number of speakers available in your system, a variety of different sound field options are available for both theReference and Wide modes.5-Channel Stereo This mode takes advantage of multiple speakers to place a stereo signal at both the front and back of a room. Depending on whether the AVR7-Channel Stereo has been configured for either 5.1 or 6.1/7.1 operation, one of these modes, but not both, is available at any time. Ideal for playing music insituations such as a party, it places the same signal at the front-left and surround-left, and front-right and surround-right speakers.The center channel is fed a summed mono mix of the in-phase material of the left and right channels.Surround This mode turns off all surround processing and presents the pure left- and right-channel presentation of two-channel stereo programs.Off (Stereo)Dolby Headphone Dolby Headphone enables ordinary stereo headphones to portray the sound of a five-speaker surround-playback system. The DH1 mode createsDH1 headphone presentation that resembles a small, well-damped room and is appropriate for use with both movies and music-only recordings.DH2 The DH2 mode creates a more acoustically live room particularly suited to music listening. The DH3 mode creates a larger room, more like aDH3 concert hall or movie theater.
