THX Surround EX: 6.1 output with Dolby Digital Surround EX
Processing: Re-Equalization,Timbre Matching
THX Surround EX – Dolby Digital Surround EX is a joint development of Dolby
Laboratories and the THX division of Lucasfilm 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, but
named Rear in the processor), places sounds behind the listener in addition to the
front, center, surround, 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 before.
Movies that were created using the Dolby Digital Surround EX technology may
exhibit wording to that effect on the packaging when released on DVD. A list of
movies created using this technology can be found on the Dolby web site at
www.dolby.com. A list of DVD titles encoded with this technology can be found on
the THX web site at www.thx.com.
Bearing the THX Surround EX logo, the processor will faithfully reproduce this
technology in the home when in THX Surround EX mode.
The processor also allows you to engage THX Surround EX with 5.1-channel
material that is not encoded with Dolby Digital Surround EX. Rear channel content
will be program dependent and may or may not be pleasing depending on the
soundtrack and your preference.
In compliance with THX, Bass/Treble, Level Trim, and Balance adjustments are reset to 0 dB when a THX
mode is selected, after which you can make adjustments with THX engaged. When THX is Off, previous
settings except Balance are restored. Due to the nature of bitstreams, adjustments made with THX
engaged will be reset to 0 dB if the source is paused for longer than 3 seconds.
Outputs indicated are the number of output channels as follows:
6.1 = L-Front, Center, R-Front, R-Surround, Rear*, L-Surround, LFE/Subwoofer
7.1 = L-Front, Center, R-Front, R-Surround, R-Rear, L-Rear, L-Surround, LFE/Subwoofer
* If two rear speakers are used, the same rear channel information goes to both.
