Additional information
Adaptive Decorrelation
In a movie theatre, a large number of surround speakers help create an enveloping surround sound experience,
but in a home theatre there are usually only two speakers. This can make the surround speakers sound like head-
phones that lack spaciousness and envelopment. The surround sounds will also collapse into the closest speaker
as you move away from the middle seating position. Adaptive Decorrelation slightly changes one surround chan-
nel’s time and phase relationship with respect to the other surround channel. This expands the listening position
and creates-with only two speakers- the same spacious surround experience as in a movie theatre.
THX Ultra2/Select2 Plus
Before any home theatre component can be THX Ultra2/Select2 Plus certified, it must incorporate all the features
above and also pass a rigorous series of quality and performance tests. Only then can a product feature the THX
Ultra2/Select2 Plus logo, which is your guarantee that the Home Theatre products you purchase will give you
superb performance for many years to come. THX Ultra2/Select2 Plus requirements cover every aspect of the
product including pre-amplifier and power amplifier performance and operation, and hundreds of other param-
eters in both the digital and analog domain.
THX Surround EX
THX Surround EX - Dolby Digital Surround EX is a joint development of Dolby Laboratories and the 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 opportu-
nity for more detailed imaging behind the listener and brings more depth, spacious ambience and sound localiza-
tion 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 http://www.dolby.com.
Only amplifier 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 encoded. 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.
Boundary Gain Compensation
TM
Depending on the listener’s and the subwoofer’s position, the listener may experience an excessive bass effect.
This feature compensates for excessive bass resulting from a boundary gain effect. This feature is designed to
operate when used with a subwoofer certified to THX Ultra2/Select2
TM
specifications.
THX Loudness Plus Description
THX Loudness Plus is a new volume control technology featured in THX Ultra2 Plus
TM
and THX Select2 Plus
TM
Certified amplifiers. With THX Loudness Plus, home theater audiences can now experience the rich details in
a surround mix at any volume level. A consequence of turning the volume below Reference Level is that certain
sound elements can be lost or perceived differently by the listener. THX Loudness Plus compensates for the tonal
and spatial shifts that occur when the volume is reduced by intelligently adjusting ambient surround channel
levels and frequency response. This enables users to experience the true impact of soundtracks regardless of the
volume setting. THX Loudness Plus is automatically applied when listening in any THX listening mode. The new
THX Cinema, THX Music, and THX Games modes are tailored to apply the proper THX Loudness Plus settings for
each type of content.
