DTS 96/24
DTS 96/24 is an extension of the original DTS Digital
Surround which offers high quality 96 kHz / 24-bit audio
using a DTS 96/24 decoder. This format is also fully
backward compatible with all existing decoders. This
means that DVD players can play this software using a
conventional DTS 5.1 channel decoder.

the amount of data needed to represent the analog audio.
PCM audio can be found on CDs and some DVDs.
About THX
®
THX is an exclusive set of standards and technologies
established by the world-renowned film production
company, Lucasfilm Ltd. These were designed to make
film soundtracks, in both movie theaters and in your
home theater, as faithful as possible to what the director
intended.
The THX technologies are explained below. See
www.thx.com for more detailed information.
THX Cinema™ processing
THX engineers developed patented technologies to
accurately translate the sound from the movie theater
environment into the home, correcting the tonal and
spatial errors that occur. When the THX indicator shows
in the display, THX features are automatically added in
Cinema modes (see Using the Home THX modes on
page 45).
Re-Equalization™
The tonal balance of a film soundtrack will be excessively
bright and harsh when played back over audio
equipment in the home because film soundtracks were
designed to be played back in large movie theaters using
very different professional equipment. Re-Equalization
restores the correct tonal balance for watching a movie
soundtrack in a small home environment.
Timbre Matching™
This feature filters the sound going to the surround
speakers so that it more closely matches the sound
coming from the front speakers. This ensures seamless
panning between the front and surround speakers.
Adaptive Decorrelation™
By slightly changing one surround channel's time and
phase relationship with respect to the other surround
channel, Adaptive Decorrelation expands the listening
position and creates the same spacious surround
experience as in a movie theater using only two speakers.
THX Ultra2™
Before any home theater component can be THX Ultra2™
certified, it must incorporate all the features described
here and also pass a rigorous series of quality and
performance tests. THX Ultra2™ requirements cover
every aspect of the product including pre-amplifier
performance and operation, and hundreds of other
parameters in both the digital and analog domain.
THX Surround EX™
THX Surround EX-Dolby Digital Surround EX is a joint
development of THX Ltd. and Dolby Laboratories, Inc.
This technology reproduces an additional surround back
channel, bringing greater depth, spacious ambience,
sound localization and detailed imaging behind the
listener.
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 may
have unpredictable results.
