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 sound

 

field is available. Even if a source does not contain specific EX encoding, the special algorithms may be used to 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

DTS-ES 6.1 Discrete

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 decodes full-range, discrete, left, center right, right surround and left surround channels from either matrix surround-encoded

Movie

programs and 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 II Game mode is designed to enhance the soundtrack

Game

of video games from either dedicated consoles or computers.The Pro Logic mode re-creates original Pro Logic processing for those who

Pro Logic

prefer that presentation.

 

 

Dolby Pro Logic IIx

Dolby Pro Logic IIx is the latest extension of Dolby Laboratory’s benchmark matrix surround technology which creates a discrete 7.1 sound field from

Movie

matrix surround or two-channel stereo sources when your system is configured for surround back speakers. Movie, Music and Game versions are

Music

available that customize the processing to the type of source in use. These modes may also be used to create 7.1 sound fields from 5.1 digital

Game

soundtracks.

 

 

Logic 7 Cinema

Exclusive to Harman Kardon for A/V receivers, Logic 7 is an advanced mode that extracts the maximum surround information from either

Logic 7 Music

surround-encoded programs or conventional stereo material. When your system has been configured for use with Surround Back speakers

 

(see page 41), you may choose between either 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. The

 

Logic 7 M (or Music) mode 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 seems broader and wider than when the subwoofer is the sole source of bass energy. Logic 7/7 may also be used

 

to add surround back channels to many 5.1 digital soundtracks.

 

 

DTS Neo:6 Cinema

These two modes are available when any analog source is playing to create a three-channel, five-channel or six-channel surround presentation from

DTS Neo:6 Music

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.

 

 

DTS 96/24

DTS 96/24 is available on specially encoded (and labeled) optical discs that offer five channels of audio with a 96kHz sampling rate that delivers

 

greatly improved audio performance. When a DTS 96/24 disc is in use and the player is connected with a digital link, this mode is selected

 

automatically.

 

 

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.

 

 

Dolby Virtual Speaker

Dolby Virtual Speaker technology uses a next-generation advanced algorithm to reproduce the dynamics and surround sound effects of a precisely

Reference

placed 5.1-channel speaker system using only front left and right speakers. In the Reference mode, the apparent width of the sound across the front

Wide

image is defined by the distance between the two speakers. The Wide mode provides a wider, more spacious front image when the two speakers are

 

close together. Depending on the number of speakers available in your system, a variety of different sound field options are available for both the

 

Reference and Wide modes.

 

 

5-Channel Stereo

This mode takes advantage of multiple speakers to place a stereo signal at both the front and back of a room. Depending on whether the AVR

7-Channel Stereo

has been configured for either 5.1 or 6.1/7.1 operation, one of these modes, but not both, is available at any time. Ideal for playing music in

 

situations such as a party, it places the same signal at the front-left and 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)

 

 

 

Dolby Headphone (DH)

Dolby Headphone enables ordinary stereo headphones to portray the sound of a five-speaker surround-playback system.
