DESCRIPTION
THX ® is an exclusive set of standards and technologies
established by the world-renowned fi lm production
company, Lucasfi lm Ltd. THX resulted from George
Lucas’ desire to reproduce the movie soundtrack as
faithfully as possible both in the movie theater and in
the home theater.
THX engineers developed patented technologies to
accurately translate the sound from a movie theater
environment into the home, correcting the tonal and
spatial errors that occur.
When the THX mode of the unit is on, three distinct
THX technologies are automatically added:
Re-Equalization-restores the correct tonal balance
for watching a movie in a home environment.
These sounds are otherwise mixed to be brighter
for a large movie theater. Re-EQ compensates for
this and prevents the soundtracks from being overly
bright and harsh when played in a home theater.
Timbre Matching-fi lters the information going to the
surround speakers so 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-slightly changes one surround
channel’s time and phase relationship with respect to
the other surround channel.
This expands the listening position and creates with
only two surround speakers the same spacious
surround experience as in a movie theater with
multiple surround speakers.
The unit was required to pass a rigorous series
of quality and performance tests, in addition to
incorporating the technologies explained above, in
order to be THX certifi ed.
THX requirements cover every aspect of performance
including pre-amplifier and power amplifier
performance and operation, and hundreds of other
parameters in both the digital and analog domain.
Movies which have been encoded in Dolby Digital,
DTS, Dolby Pro Logic, stereo and Mono will all
benefi t from the THX mode when being viewed.
The THX mode should only be activated when
watching movies which were originally produced for
a movie theater environment.
THX need not be activated for music, movies
made especially for TV, or shows such as sports
programming, talk shows, etc.
This is because they were originally mixed for a small
room environment.

THX Surround EX—Dolby DIgital Surround EX is a
joint development of Dolby Laboratories and THX
Ltd.
In a movie theater, fi lm soundtracks that have been
encoded with Dolby Digital Surround EX technology
are able to reproduce an extra channel which has
been added during the mixing of the program. This
channel, called Surround Back, places sounds
behind the listener in addition to the currently
available front left, front center, front right, surround
right, surround left and subwoofer channels. This
additional channel provides the opportunity for more
detailed imaging behind the listener and brings more
depth, spacious ambience and sound localization
than ever before.
Movies that were created using the Dolby Digital
Surround EX technology, when released into the
home consumer market may exhibit wording to that
effect on the packaging. A list of movies created
using this technology can be found on the Dolby
web site at www.dolby.com. A list of available DVD
software titles encoded with this technology an be
found at www.thx.com.
Only receiver and controller products bearing the
THX Surround EX logo, when in the THX Surround
EX mode, faithfully reproduce this new technology
in the home. This product may also engage the
THX Surround EX mode during the playback of 5.1
channel material that is not Dolby Digital Surround
EX eocnded. In such case, the information delivered
to the Surround Back channel will be program
dependent and may or may not be very pleasing
depending on the particular soundtrack and the
tastes of the individual listener.
“SURROUND EX™” is a trademark of Dolby
Laboratories. Used under authorization.
T h e T H X U l t r a 2 s p e c i f i c a t i o n p r o v i d e s
uncompromised 7.1 channel playback of any multi-
channel program, whether movie soundtracks or
music over the widest possible seating area.
There are an additional two processing’s for THX
Ultra2 as bellow.
A.S.A. (Advanced Speaker Array)
“ASA” is a proprietary THX technology which
processes the sound fed to 2 surround and 2
surround back speakers to provide the optimal
surround sound experience. When you set up your
home theater system using all eight speaker outputs
(Left, Center, Right, Surround Right, Surround
Back Right, Surround Back Left, Surround Left and
Subwoofer), placing the two Surround Back speakers
close together facing the front of the room as shown
in the diagram will provide the largest sweet spot. If
for practical reasons you have to place the Surround
Back speakers apart, you will need to go to the THX
Audio Set-up screen and choose the setting that
most closely corresponds to the speaker distance,
which will re-optimize the surround sound-fi eld. ASA
is used in two new surround modes; THX Ultra2
Cinema, THX Music Mode and THX Games mode.
B.G.C. (Boundary Gain Compensation)
If your chosen listening room layout (for practical or
aesthetic reasons) results in most of the listeners
being close to the rear wall, the resulting bass level
can be suffi ciently reinforced by the boundary that
the overall sound quality becomes “boomy”. THX
Ultra2 receivers contain the BGC (Boundary Gain
Compensation) feature to provide an improved bass
balance. BGC can be selected by choosing “THX
Ultra2 Subwoofer-Yes” from the “Boundary Gain
Compensation” section of the “THX Audio setup
menu”.
Neural-THX ® Surround has been chosen as the
offi cial surround sound broadcast format for leading
FM/HD and satellite radio and television stations
worldwide. Neural-THX Surround delivers the rich
envelopment and discrete image detail of surround
sound in a format 100% compatible with stereo.
Neural-THX Surround draws the brain’s attention
to sonic details in musical instruments, vocals and
ambience that are typically masked by other playback
systems. This allows the listener to fully experience
the richness and subtleties in recorded performance
as never before for both surround encoded material
and regular stereo material such as CDs or digital
media players.
Neural-THX Surround: Taking Surround to the Next
Level.
