T-D (Theater-Dimensional)
In this mode, you can enjoy a virtual playback of multichannel surround sound
even with only two or three speakers. This works by controlling how sounds
reach the listener’s left and right ears.
THX
THX is a series of specications for the accurate reproduction of movies
propounded by the lm director George Lucas. THX listening modes include
the THX Cinema mode, etc. Using technology such as THX Loudness Plus and
Timbre Matching, the sound of a movie theater is reproduced accurately.
THX technology:
A movie soundtrack is mixed in a large-scale theater specially made for mixing
that is called a dubbing stage on the assumption that the soundtrack is played
in such theaters with similar equipment and conditions. These soundtracks
are recorded as is, even when recording to a DVD-Video, for example, without
making any modications to suit a home theater environment. THX technology
is able to reproduce the movie theater sound accurately in a home theater
environment by minimizing acoustic and spatial deviation.
• THX Loudness Plus
THX Loudness Plus is a new volume control technology mounted on THX Ultra
and THX Select-certied AV receivers. With THX Loudness Plus, home theater
audience can experience the rich details of surround sound at any volume level.
If the volume is turned down below the reference level, elements of sound in a
certain range are lost, or the sound is perceived dierently by audience. THX
Loudness Plus compensates for the tonal and spatial shifts that occur when the
volume is reduced, by intelligently adjusting ambient surround channel levels and
frequency response.
• Re-EQ
The speakers for the front channel in a movie theater are installed behind the
screen. For this reason the high range is enhanced in the sound track of the front
channel in view of acoustic characteristics such as the necessity to penetrate the
screen. Re-EQ adjusts the soundtrack with the enhanced high range to make it
suitable for a home theater.
• Timbre Matching
The perception of human ears diers depending on the sound direction. Movie
theaters have many surround speakers installed, so they are excellent at
surrounding the viewers with natural sound, but home theaters have only two
surround speakers installed. The Timbre Matching function lters the signals sent
to the surround speakers, and adjusts the tonal characteristics of front speakers
and surround speakers to create smooth sound movement from front speakers to
surround speakers.
• Adaptive Decorrelation
While movie theaters have many surround speakers to enable the experience
where viewers are surrounded with sound, home theaters normally have only two
surround speakers. Such two surround speakers give a headphone-like sound,
not a broad and embracing surround sound. If a listener moves away from the
middle position between the surround speakers, the sound from the surround
speakers is absorbed into the sound from the nearby speakers, and cannot be
distinguished any more. Adaptive Decorrelation changes the time axis and phase
between the surround channels so that you can enjoy the same spatial sound
with two surround speakers as in a movie theater .
• ASA (Advanced Speaker Array)
ASA is a technology patented by THX to provide a broad surround sound
experience by adjusting the sounds of two surround speakers on the sides and
two surround speakers at the back. When installing the surround back speakers,
be sure to select the distance between the two surround back speakers in the
THX Audio settings. This setting optimizes the surround sound environment.
THX listening modes:
– THX Cinema: Use this mode in a home theater environment to play the
soundtrack that was recorded on the assumption that it is played in a movie
theater or similar large area. In this mode, THX Loudness Plus is set to the
theater level, and Re-EQ, Timbre Matching and Adaptive Decorrelation are all
enabled.
– THX Games: Use this mode for high-delity spatial reproduction of game
sound. THX Loudness Plus is set to a level suited to the audio level of the
game, and Timbre Matching is enabled.
– THX Music: This mode mainly adjusts the playback of music sources that are
mastered to a much higher quality obviously than movie audio. In this mode,
