MODE FEATURES DELAY TIME RANGE

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.

Center: 0 ms – 5 ms Initial Setting – 0 ms Surround: 0 ms – 15 ms Initial Setting – 0 ms

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	Movie and Emulation:
MOVIE	that decodes full-range, discrete left, center right, right surround and left surround channels	10 ms - 25 ms,

	while the Pro Logic II Music mode should be used with musical selections that are recorded with	Initial Setting - 0 ms
	matrix surround or even with normal stereo mode, creating separate rear left and rear right signals
	in any case. The Pro Logic II Emulation mode creates compelling five-channel surround sound from
	conventional stereo recordings.
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.
DTS Neo:6 Cinema	These two modes are available when any analog source is playing to create a six-channel	Delay time not adjustable
DTS Neo:6 Music	surround presentation from conventional Matrix-encoded and traditional Stereo sources. Select
	the Cinema version of Neo:6 when a program with any type of analog Matrix surround encoding
	is present. Select the Music version of Neo:6 for optimal processing when a nonencoded,
	two-channel stereo program is being played.
DOLBY 3 STEREO	Uses the information contained in a surround-encoded or two-channel stereo program to	No surround channels
	create center-channel information. In addition, the information that is normally sent to the
	rear-channel surround speakers is carefully mixed in with the front-left and front-right
	channels for increased realism. Use this mode when you have a center-channel speaker
	but no surround speakers.
THEATER	The THEATER mode creates a sound field that resembles the acoustic feeling of a	Delay time not adjustable
	standard live performance theater, with stereo and even pure mono sources.
