THX Surround EX processes Dolby Digital Surround EX encoded
discs. THX Surround EX is a joint development of Dolby
Laboratories and the THX division of Lucasfilm Ltd. Movie
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 front left, front centre, 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
localisation than ever before.
When released to the home consumer market, movies that were
created using the Dolby Digital Surround EX technology, may (but
some don’t!) have a note 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
.
Only receiver and controller products bearing the ‘THX Surround
EX’ logo, such as the AV32R THX Surround EX Plus faithfully
reproduce this new sound format in the home, when switched into
the THX Surround EX mode.
You can also activate the ‘THX Surround EX’ mode during the
playback of standard 5.1 channel material (i.e. movies not
including a Dolby Digital Surround EX encoded back channel). In
such a case the information delivered to the Surround Back
THX Surround EX
(only available if your
AV32R is equipped with
the THX Surround EX
Plus option)
