Anthem AVM 20 v2 - Manual (Page 36)

THX Surround EX: 6.1 output with Dolby Digital 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 20), 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 20 will faithfully reproduce this
technology in the home when in THX Surround EX mode.
The AVM 20 also allows you to engage THX Surround EX during playback of 5.1
channel material that is not Dolby Digital Surround EX encoded. 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.
Note: Other THX modes can be applied to non-flagged Dolby Digital Surround
EX DVDs, however Rear channel information will be lost. If you are applying
THX to non-flagged DVDs, be sure to select THX Surround EX.
With flagged Dolby Digital EX, other THX modes are incompatible since they
do not retain the decoded Rear channel.
THX for DTS-ES: 6.1 output with DTS Neo:6, DTS-ES Matrix, and DTS-ES Discrete
Processing: Re-Equalization,Timbre Matching
THX processing can also be engaged when playing DTS-ES material (Matrix or
Discrete), and DTS 5.1-channel material with Neo:6 activated.
Outputs indicated are the number of output channels as follows:
5.1 = L-Front, Center, R-Front, R-Surround, L-Surround, Subwoofer
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 will go to both.
Note: In compliance with THX requirements, Bass/Treble, Surround Mode Level, and Balance
adjustments are set to +0.0 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 5.6 and 5.7). Also note that due to the nature of the
digital bitstream, any adjustments made while THX is engaged will be reset to +0.0 dB if the
program is paused for longer than 3 seconds.
