DELAY TIME RANGE

 

 

 

DOLBY DIGITAL

Available only with digital input sources encoded with Dolby Digital data. It provides

Center: 0 ms – 5 ms

 

up to five separate main audio channels and a special dedicated Low-Frequency Effects

Surround: 0 ms – 15 ms

 

channel.

 

 

 

 

DTS

Available only with digital input sources encoded with DTS data. Available on special

Delay not adjustable

 

DVD, LD and audio-only discs, DTS provides up to five separate main audio channels and

 

 

a special dedicated low-frequency channel.

 

DOLBY PRO LOGIC

The standard mode for analog surround sound decoding. It uses information encoded

 

in a two-channel stereo recording to produce four distinct outputs: Left, Center, Right and

 

a Mono Surround channel. Use this mode for accurate reproduction of programs bearing

 

the Dolby Surround, DTS Stereo, UltraStereo or other “Surround” logos. Surround-encoded

 

programs include videocassette, DVD and LD movies, TV and cable programs, radio

 

programs and audio CDs. Dolby Pro Logic processing may also be used to provide a

 

pleasing surround effect with some stereophonic source material that does not carry

 

surround encoding.

15 ms – 30 ms

Initial Setting = 20 ms

LOGIC 7 C LOGIC 7 M

An advanced mode that extracts the maximum surround information from either

Delay time not adjustable

surround-encoded programs or conventional stereo material. When used with encoded

 

material, decoding is more accurate in terms of the placement of sounds, and fades and

 

pans are much smoother and more realistic than with other decoding techniques. Logic 7

 

also delivers increased spaciousness and a wider sound stage when it is used with con-

 

ventional stereo recordings and music programs. The Logic 7C or Cinema mode is tailored

 

to provide an optimal sound field for movie soundtracks. The Logic 7M or Music mode

 

uses a decoding formula that is best suited to music.

 

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

VMAx

Surround processing uses matrix surround decoding to simulate a standard movie or

27.3 ms (not adjustable)

stage theater.

 

When only the two front-channel loudspeakers are used, Harman’s patented VMAx mode

No surround channels

delivers a three-dimensional sound space with the illusion of “phantom speakers” at the

 

center and surround positions.

 

STEREO

This mode turns off all surround processing and presents the pure left and right

No surround channels

channel presentation of two-channel stereo programs.
