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 encoded. 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.
Advanced Speaker Array (ASA)
ASA is a proprietary THX technology which processes the
sound fed to 2 side and 2 back surround 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 THX
Audio Set-up screen and choose the setting that most
closely corresponds to the speaker spacing, which will re-
optimize the surround sound-field.
ASA is used in three new modes; THX Select2 Cinema, THX
MusicMode and THX Games Mode.
THX Select2 Cinema mode
THX Select2 Cinema mode plays 5.1 movies using all 8
speakers giving you the best possible movie watching
experience. In this mode, ASA processing blends the side
surround speakers and back surround speakers providing
the optimal mix of ambient and directional surround sounds.
DTS-ES (Matrix and 6.1 Discrete) and Dolby Digital Surround
EX encoded soundtracks will be automatically detected in
Select2 Cinema mode if the appropriate flag has been
encoded.
Some Dolby Digital Surround EX soundtracks are missing
the digital flag that allows automatic switching. If you know
that the movie that you are watching is encoded in Surround
EX, you can manually select the THX Surround EX playback
mode, otherwise THX Select2 Cinema mode will apply ASA
processing to provide optimum replay.
THX MusicMode
For the replay of multi-channel music the THX MusicMode
should be selected. In this mode THX ASA processing is
applied to the surround channels of all 5.1 encoded music
sources such as DTS, Dolby Digital and DVD-Audio to
provide a wide stable rear soundstage.
THX Games Mode
For the replay of stereo and multi-channel game audio the
THX Games Mode should be selected. In this mode THX ASA
processing is applied to the surround channels of all 5.1 and
2.0 encoded game sources such as analog, PCM, DTS and
Dolby Digital. This accurately places all game audio
surround information, providing a full 360 degree playback
environment. THX Games Mode is unique as it gives you a
smooth transition of audio in all points of the surround field.

Selecting fine audio equipment such as the unit
you’ve just purchased is only the start of your
musical enjoyment. Now it’s time to consider how
you can maximize the fun and excitement your
equipment offers. This manufacturer and the
Electronic Industries Association’s Consumer
Electronics Group want you to get the most out of
your equipment by playing it at a safe level. One that
lets the sound come through loud and clear without
annoying blaring or distortion-and, most importantly,
without affecting your sensitive hearing.
Sound can be deceiving. Over time your hearing
“comfort level” adapts to higher volumes of sound.
So what sounds “normal” can actually be loud and
harmful to your hearing. Guard against this by
setting your equipment at a safe level BEFORE your
hearing adapts.
To establish a safe level:
• Start your volume control at a low setting.
• Slowly increase the sound until you can hear it
comfortably and clearly, and without distortion.
Once you have established a comfortable sound
level:
• Set the dial and leave it there.
Taking a minute to do this now will help to prevent
hearing damage or loss in the future. After all, we
want you listening for a lifetime.
We Want You Listening For A Lifetime
Used wisely, your new sound equipment will
provide a lifetime of fun and enjoyment. Since
hearing damage from loud noise is often
undetectable until it is too late, this manufacturer
and the Electronic Industries Association’s
Consumer Electronics Group recommend you avoid
prolonged exposure to excessive noise. This list of
sound levels is included for your protection.
