With the addition of the surround back channel, this 
new format has all 6.1 channels recorded indepen-
dently for a completely discrete digital format. Since 
all channels are recorded independently, high-fidel-
ity surround playback with an increased feeling of a 
separated sound space is achieved.

 

This format has the surround back channel matrix 
encoded and inserted into the left and right surround 
channels so that at playback the output for the left, 
right, and back surround channels are decoded using 
a high-precision matrix decoder.

 

Automatically changes to this mode when playing 
back sources with surround tracks that were encoded 
using the DTS 96/24 technology.

 

THX is an exclusive set of standards and technologies 
established by the world-renowned film production com-
pany, Lucasfilm Ltd. THX grew from George Lucas’ 
personal desire to make your experience of the film 
soundtrack, in both movie theaters and in your home the-
ater, as faithful as possible to what the director intended.
Movie soundtracks are mixed in special movie theaters 
called dubbing stages and are designed to be played back 
in movie theaters with similar equipment and conditions. 
This same soundtrack is then transferred directly onto 
LD, VHS tape, DVD, etc., and is not changed for play-
back in a small home theater environment.
THX engineers developed patented technologies to 
translate accurately the sound from the movie theater 
environment into the home, correcting the tonal and spa-
tial errors that occur. On this product, when the THX 
indicator is on, THX features are automatically added in 
Cinema Modes (e.g. THX Cinema, THX Surround EX).

 

This is the conventional 5.1 channel THX format. 
This mode should be used only when playing back 
sources that were mixed for playback in large movie 
theater environments.

 

“THX Surround EX - Dolby Digital Surround EX” 
is a joint development of Dolby Laboratories and the 
THX division of THX Ltd.
In a movie theater, film soundtracks that have been 
encoded with Dolby Digital Surround EX technol-
ogy 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 avail-
able 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 localiza-
tion than ever before.

When released to the home consumer market, mov-
ies that were created using the Dolby Digital Sur-
round EX technology, may 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 
http://www.dolby.com. 
The TX-NR801/TX-NR801E can play the 5.1 chan-
nel sources in THX surround EX mode, even if the 
source is not encoded in Dolby Digital Surround EX 
format. In this case, the sound actually output from 
the surround back channels depends on the source 
and may not fit your tastes.

 

This mode is suitable for playing back monaural record-
ing such as old movie soundtracks. The center channel 
delivers the unprocessed original sound, whereas the 
other channels deliver the center-channel sound pro-
cessed with the appropriate reverberation. This allows 
you to enjoy monaural sound with the atmosphere of a 
movie theater.

 

This mode reproduces a natural surround environment 
by using seven speaker channels. The sound effects 
move smoothly toward the surround back. This mode is 
good for music and TV sports programs.

 

This mode is appropriate for classical and opera music. 
The center channel is cut and the surround channels are 
emphasized to widen the stereo image. It will simulate 
the natural reverberation that is created in large halls.

 

This mode is suitable for acoustical instrumental sounds, 
vocals, and jazz music. By emphasizing the front stereo 
image, it will simulate the acoustics that you would 
experience in front of the stage.

 

This mode is for rock and popular music. The lively 
sounds are enhanced for a powerful acoustic image that 
simulates the feeling of being at a club or rock concert.

 

This mode gives realistic acoustics to TV programs that 
are aired from TV studios. It enhances the entire sur-
round sound and clarity of the conversation.

 

This mode is designed for playing background music. 
The front, surround, and surround back channels create 
a stereo image that encompasses the entire area.
