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

GAME

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. 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.

 

 

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

 

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. 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.
