Surround Mode Chart

MODE	FEATURES
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 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
DTS-ES 6.1 Discrete	source will automatically 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
MOVIE	that decodes full-range, discrete left, center right, right surround and left surround channels
MUSIC	from matrix surround encoded programs and conventional stereo sources when
DOLBY PRO LOGIC	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 optimized 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
	normal 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.
DOLBY PRO LOGIC IIx	Dolby Pro Logic IIx is the latest extension of Dolby Pro Logic II technology that creates a discrete
MUSIC	6.1 and 7.1 sound field from matrix surround or two-channel stereo sources in systems
MOVIE	configured for surround back speakers. Both Movie and Music versions of Pro Logic IIx are
GAME	available. Movie, Music and Game versions of Pro Logic IIx are available. 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
Logic 7 Music	maximum surround information from either surround-encoded programs or conventional stereo
Logic 7 Enhance	material. Depending on the number of speakers in use and the 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.
