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 laser discs 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 trigger the selection of one of the two
DTS-ES 6.1 Discrete 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 decodes full-range, discrete, left, center right, right surround and left surround channels from either matrix surround-encoded
Movie programs or 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 mode re-creates original Pro Logic processing for
Pro Logic those who prefer that presentation.
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 surround or two-channel
Music stereo sources in systems configured for surround back speakers. Both Movie and Music versions of Pro Logic IIx are available. These modes may also be applied
Movie to a six-channel source connected to the 8-Channel Direct Inputs so that the sound field is enhanced by adding back surround channels, as well as to enable
the MAIN DOWNMIX option in the multiroom system so that
a six channel direct input may be used as a source for the remote room.
Logic 7 Cinema Exclusive to Harman Kardon for receivers, Logic 7 is an advanced mode that extracts the maximum surround information from either surround-encoded programs
Logic 7 Music or conventional stereo material. When your system has been configured for use with Surround Back Speakers (see page 25), you may choose between either
Logic 7 Enhance 7.1 or 5.1 versions of the Logic 7 modes, while only the 5.1 versions are available when there are no Surround Back Speakers. 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 other 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, available only when the 5.1 option is chosen, is an extension of the Logic 7 modes that is primarily used with musical programs. Logic 7 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 with analog sources playing to create a three-channel, five-channel or six-channel surround presentation from matrix-encoded
DTS Neo:6 Music or stereo sources. Select the Cinema version of Neo:6 when a program with 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.
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.
VMAx Near When only the two front-channel loudspeakers are used, VMAx delivers a three-dimensional sound space with the illusion of “phantom speakers” at the center
VMAx Far and surround positions. The VMAx N, or “Near Field” mode should be selected when your listening position is less than five feet from the speakers. The VMAx F, or
“Far Field,” mode should be selected when your listening position is greater than five feet from the speakers.
Dolby Virtual Speaker Dolby Virtual Speaker uses advanced technology to simulate the sonic signature of a speaker location even when there is no speaker physically present in that
Reference location. The Reference (“REF”) mode activates any missing speakers to simulate a 5.1 presentation with accurate localization. The Wide mode virtualizes
Wide the locations of the front-channel speakers to create a wider image and a more enveloping sound field. It is available no matter how many speakers are present.
5-Channel Stereo These modes take advantage of multiple speakers to place a stereo signal at both the front and back of a room. They places the same signal at the front-left and
7-Channel Stereo 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) When
SURROUND OFF
is selected, the unit is in a “bypass” mode with no bass management. When
SURROUND OFF+DSP
is selected, the signal is digitized and bass management settings are applied.
Dolby Headphone Dolby Headphone enables ordinary stereo headphones to portray the sound of a five-speaker surround-playback system. The DH1 mode creates
DH1 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 a
DH3 concert hall or movie theater.
