In this mode, sound pressure is emphasized to heighten
live feel.
■ Game-RPG
In this mode, the sound has a dramatic feel with a similar
atmosphere to Orchestra mode.
■ Game-Sports
Suitable for audio source with much reverberation.
■ Mono
Use this mode when watching an old movie with a mono
soundtrack, or use it to separately reproduce soundtracks
in two different languages recorded in the left and right
channels of some movies. It is also suitable for DVDs or
other sources containing multiplexed audio.
■ Multich (Multichannel)
Mode suitable for playing sources recorded in multichannel
PCM.
■ Orchestra
Suitable for classical or operatic music. This mode
emphasizes the surround channels in order to widen the
stereo image, and simulates the natural reverberation of a
large hall.
■ 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 Ultra2 Plus and THX Select2 Plus 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
intention of it being 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 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.
– THX Music : Use mainly for music sources that are
clearly mastered to a much higher quality than movie
