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.
