feature. Activating the Multi-zone feature while this
mode is selected automatically switches the listening
mode to Direct.
■ Stereo
In this mode, sound is output from the front left and right
speakers and subwoofer.
■ Studio-Mix
Suitable for rock or pop music. Listening to music in this
mode creates a lively sound field with a powerful acoustic
image, like being at a club or rock concert.
■ 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 specifications for the accurate
reproduction of movies propounded by the film director
George Lucas. THX listening modes include the THX
Cinema mode, and 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 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
sound tracks are recorded as is, even when recording
to a DVD-Video, for example, without making any
modifications to suit a home theater. THX technology is
able to reproduce the theater sound in a home theater
environment by minimizing acoustic and spatial deviation.
•
THX Loudness Plus
THX Loudness Plus is a new volume control technology
featured in THX certified AV receivers. With THX
Loudness Plus, home theater audiences 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 differently by audience. THX Loudness
Plus compensates for the tonal and spatial shifts that
occur when the volume level is reduced, by intelligently
correcting the levels of the surround channels and their
frequency response in the environment.
•
Re-EQ
The speakers for the front channel are installed behind the
screen in a movie theater. For this reason the high range
is enhanced in the front channel of the sound track to take
account of acoustic characteristics such as the necessity
to penetrate the screen. Re-EQ adjusts soundtrack with
enhanced high range to make it suitable for home theater.
•
Timbre Matching
The perception of the human ear differs depending on the
direction of the sound. Movie theaters have many surround
speakers installed so they are great at surrounding the
viewer with natural sound, but home theaters have only
two surround speakers installed. The Timbre Matching
function filters 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
Although movie theaters have many surround speakers
to surround the room 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 the listener moves away
from the middle of the surround speakers, sound from
the surround speakers mixes with that from the near
speakers and cannot be distinguished any more. Adaptive
Decorrelation slightly changes the time axis and phase
between the surround channels so you can enjoy the same
kind of breadth of sound you can in a movie theater even
with only two surround speakers.
•
ASA (Advanced Speaker Array)
ASA is a technology patented by THX to provide a broad
surround sound experience by adjusting the side and back
surround speaker sounds respectively. When installing the
surround back speakers, first 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 in a home theater environment
for playing a soundtrack that was recorded with the

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 for high-fidelity 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.
–

clearly mastered to a much higher quality than movie
audio. THX Loudness Plus is set to a level suited to the
playback of music and Timbre Matching is enabled.
–
THX I/S Cinema: The THX I/S Cinema mode provides
a high-quality surround sound experience by expanding
movie sources recorded in 5.1 ch for 7.1 ch playback.
In this mode, the THX ASA processing technology gives
smooth transition between side and back surround
sounds creating the best atmosphere and directional
sense of surround sound.
–
THX I/S Games: Select the THX I/S Games mode to
play game sound recorded in a multichannel format. In
this mode, the THX ASA processing technology creates
a 360-degree sound field with game sound recorded in
