MODE	FEATURES
DOLBY DIGITAL PLUS	An enhanced version of Dolby Digital encoded more efficiently, Dolby Digital Plus has the capacity for additional discrete channels
	and for streaming audio from the internet, all with enhanced audio quality. Source material may be delivered via HDMI, or decoded
	to Dolby 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 features
	found in Dolby Digital, such as night mode settings, while delivering fully lossless audio that is a true reproduction of the studio
	master recording.
DOLBY DIGITAL	Available only with digital input sources encoded with Dolby Digital data. It provides up to five separate main audio channels and a
	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 with movies 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. When the receiver is set for 6.1/7.1 operation and a Dolby Digital signal is present, the EX mode
	is automatically selected. Even if specific EX encoding is not available to provide the additional channel, the special algorithms will
	derive 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 is
	transmitted using a DTS core with high-resolution extensions. Even when only DTS 5.1 surround sound is desired (or available, if the
	multizone 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	DTS-HD Master Audio delivers bit-for-bit reproductions of the studio master recording in up to 7.1 channels, for an incredibly
MASTER AUDIO	accurate performance.
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
	laserdiscs 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 Matrix	When the speaker configuration is set for 6.1/7.1 operation, playback of a DTS-encoded program source will automatically
DTS-ES 6.1 Discrete	trigger the selection 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 II Dolby Pro Logic II is the latest version of Dolby Laboratory’s benchmark surround technology that decodes full-range, discrete left,

MOVIE	center right, right surround and left surround channels from matrix surround encoded programs and conventional stereo sources
MUSIC	when 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 is
DOLBY PRO LOGIC	optimized for movie soundtracks that are recorded with matrix surround, by creating separate center,rear left and rear right signals.
GAME	while the Pro Logic II Music mode should be used with musical selections that are recorded with matrix surround or even with nor-
	mal stereo mode, creating separate rear left and rear right signals in any case. The Pro Logic II mode creates compelling five-channel
	surround 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 IIx	Dolby 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 matrix
MUSIC	surround or two-channel stereo sources in systems configured for surround back speakers.
MOVIE	Movie, Music and Game versions of Pro Logic IIx are available.
GAME	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.
Logic 7 Cinema	Exclusive to Harman Kardon for AV receivers, Logic 7 is an advanced mode that extracts the maximum surround information from
Logic 7 Music	either surround-encoded programs or conventional stereo material. Depending on the number of speakers in use and the
Logic 7 Enhance	selection made in the SURROUND SELECT menu, the “5.1” versions of Logic 7 modes are available when the 5.1 option is
	chosen, while the “7.1” versions of Logic 7 produce a full sound field presentation, including back surround speakers when the
	“6.1/7.1” option is chosen. 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 much smoother and more realistic than with former decoding techniques. The Logic 7 M or Music mode should be
	used with analog or PCM 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 maximum bass impact. The Logic 7 E (or Enhance) mode is an extension of the Logic 7 modes that is primarily used with
	musical programs and is available with the 5.1 surround mode option selected only. Logic 7 E adds additional bass enhancement
	that circulates low frequencies in the 40Hz to 120Hz range to the front and surround speakers to deliver a less localized soundstage
	that appears broader and wider than when the subwoofer is the sole source of bass energy.
