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 AVM 50), places sounds behind the listener in addition to the

 

currently available L-Front, Center, R-Front, R-Surround, L-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 ever 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 AVM 50 will faithfully reproduce this

 

technology in the home when in THX Surround EX mode.

 

The AVM 50 also allows you to engage THX Surround EX during playback of

 

5.1-channel material that is not encoded with Dolby Digital Surround EX. The

 

information delivered to the Rear channel will be program dependent and may or

 

may not be pleasing depending on the soundtrack and your listening tastes.

In compliance with THX requirements, Bass/Treble, Surround Mode Level, and Balance adjustments are reset to 0 dB whenever a THX mode is selected, after which you can make adjustments with THX engaged if you wish to do so. When THX is turned ‘Off’, previous settings are restored, except for Balance (see sections 4.6 and 4.7). Also note that due to the nature of digital bitstreams, adjustments made while THX is engaged will be reset to 0 dB if the program 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.
