Surround Mode Chart

MODE	FEATURES		DELAY TIME RANGE
DOLBY DIGITAL	Available only with digital input sources encoded with Dolby Digital data. It provides		Center: 0 - 30ft / 9m
	up to five separate main audio channels and a special dedicated Low Frequency Effects		Initial Setting: 12ft / 3.6m
	channel.		Surround: 0 - 30ft / 9m
			Initial Setting: 10ft / 3m
DOLBY DIGITAL EX	Available when the receiver is configured for 6.1/7.1 channel operation, Dolby Digital EX is the		Center: 0 - 30ft / 9m
	latest version of Dolby Digital. When used with movies or other programs that have special		Initial Setting: 12ft / 3.6m
	encoding, Dolby Digital EX reproduces specially encoded soundtracks so that a full 6.1/7.1		Surround: 0 - 30ft / 9m
	soundfield is available. When the receiver is set for 6.1/7.1 operation and a Dolby Digital signal is		Initial Setting: 10ft / 3m
	present, the EX mode is automatically selected. Even if specific EX encoding is not available to		Surround Back: 0 - 30ft / 9m
	provide the additional channel, the special algorithms will derive a 6.1/7.1 output.		Initial Setting: 10ft / 3m
DTS 5.1	When the speaker configuration is set for 5.1-channel operation, the DTS 5.1 mode is		Delay time not adjustable
	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		Delay time not adjustable
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		Center: 0 - 30ft / 9m
MOVIE	that decodes full-range, discrete left, center right, right surround and left surround channels		Initial Setting: 12ft / 3.6m
MUSIC	from matrix surround encoded programs and conventional stereo sources when		Surround: 0 - 30ft / 9m
PRO LOGIC	an analog input or a digital input with PCM or Dolby Digital 2.0 recordings is in use. The		Initial Setting: 10ft / 3m
	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 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		Center: 0 - 30ft / 9m
MUSIC	6.1 and 7.1 sound field from matrix surround or two-channel stereo sources in systems		Initial Setting: 12ft / 3.6m
MOVIE	configured for surround back speakers. Both Movie and Music versions of Pro Logic IIx are		Surround: 0 - 30ft / 9m
	available. These modes may also be applied to a six-channel source connected to the		Initial Setting: 10ft / 3m
	8-Channel Direct Inputs	so that the sound field is enhanced by adding back surround
	channels.
Logic 7 Cinema	Exclusive to Harman Kardon for AV receivers, Logic 7 is an advanced mode that extracts the		Delay time not adjustable
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.
