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.

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".

®
offi cial surround sound broadcast format for leading
FM/HD and satellite radio and television stations
worldwide. Neural-THX Surround delivers the rich

sound in a format 100% compatible with stereo.

as never before for both surround encoded material
and regular stereo material such as CDs or digital
media players.
