Thx Surround Ex - Marantz SR9600 Service Manual

THX Surround EX—Dolby DIgital Surround EX is a
joint development of Dolby Laboratories and THX
Ltd.
In a movie theater, film 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.

The advantages of discrete multichannel systems
over matrix are well known.
But even in homes equipped for discrete
multichannel, there remains a need for high-quality
matrix decoding. This is because of the large
library of matrix surround motion pictures available
on disc and on VHS tape; and analog television
broadcasts.
The typical matrix decoder of today derives a
center channel and a mono surround channel from
two-channel matrix stereo material. It is better than
a simple matrix in that it includes steering logic to
improve separation, but because of its mono,
band-limited surround it can be disappointing to
users accustomed to discrete multichannel.
Neo:6 offers several important improvements as
follow,
• Neo:6 provides up to six full-band channels of
matrix decoding from stereo matrix material.
Users with 6.1 and 5.1 systems will derive six
and five separate channels, respectively,
corresponding to the standard home-theater
speaker layouts.
• Neo:6 technology allows various sound
elements within a channel or channels to be
steered separately, and in a way which follows
naturally from the original presentation.
• Neo:6 offers a music mode to expand stereo
nonmatrix recordings into the five- or six-
channel layout, in a way which does not diminish
