Reference

Dialogue Normalization

Dialogue Normalization (DialogNorm) is a feature of

Dolby Digital, which is used to keep the programs at the

same average listening level so the user does not have

to change the volume control between Dolby Digital,

Dolby Digital Plus and Dolby TrueHD programs. When

playing back software which has been encoded in Dolby

Digital, Dolby Digital Plus and Dolby TrueHD, sometimes

you may see a brief message in the front panel display

which will read "DialogNorm: X dB" (X being a numeric

value). The display is showing how the program level

relates with THX calibration level. If you want to play the

program at calibrated theatrical levels, you may wish to

adjust the volume. For example, if you see the following

message: "DialogNorm: + 4 dB" in the front panel

display, to keep the overall output level at THX calibrated

loudness, just turn down the volume control by 4dB.

However, unlike a movie theater where the playback

loudness is preset, you can choose your preferred

volume setting for best enjoyment.

THX Cinema Processing

THX is an exclusive set of standards and technologies

established by the world-renowned film production

company Lucasfilm Ltd. THX grew from George Lucas'

personal desire to make your experience of the film

soundtrack in both movie theaters and in your home

theater as faithful as possible to what the director

intended. Movie soundtracks are mixed in special

environments called dubbing stages and are designed to

be played back in movie theaters with similar equipment

and conditions. Most of those soundtracks are remixed

using flat response loudspeakers similar to those used

in the small home theater environment before being

transferred onto Blu-ray Discs, DVD, etc. THX engineers

developed patented technologies to accurately translate

the sound from the movie theater environment into the

home, correcting the tonal and spatial errors that occur.

On this product, when the THX indicator is on, THX

features are automatically added in Cinema modes (e.g.

THX Cinema, THX Surround EX).

Timbre Matching

The human ear changes our perception of a sound

depending on the direction from which the sound is

coming. In a movie theater, there is an array of surround

speakers so that the surround information is all around

you. In a home theater, you may only have two speakers

located to the side of your head. In this case, the Timbre

Matching feature filters the information going to the

surround speakers so that they more closely match the

tonal characteristics of the sound coming from the front

speakers. This ensures seamless panning between the

front and surround speakers.

Adaptive Decorrelation

In a movie theater, a large number of surround speakers

help create an enveloping surround sound experience.

If a home theater only has two sidewall surround

speakers, the surround speakers may sound similar to

headphones lacking spaciousness and envelopment.

Surround sounds will also collapse toward the closet

speaker as you move away from the middle seating

position. Adaptive Decorrelation slightly changes one

surround channel's time and phase relationship with

respect to the other surround experience as in a movie

theater using only two speakers.

ASA (Advanced Speaker Array)

ASA is a proprietary THX technology which processes

the audio on the two side and two back surround

speakers for the optional surround sound experience.

When you set up your home theater system using eight

speaker outputs (Left, Center, Right, Surround Right,

Surround Back Right, Surround Back Left, Surround

Left, and Subwoofer), be sure to go to the THX Audio

Setup screen and choose the setting that closely

corresponds to the back speaker spacing. This will

reoptimize the surround sound field. ASA is used in

three modes: THX Select2 Cinema, THX Select2 Music

and THX Select2 Games.
