ENGLISH DESCRIPTION THX® is an exclusive set of standards and technologies established by the world-renowned film production company, Lucasfilm Ltd. THX resulted from George Lucas' desire to reproduce the movie soundtrack as faithfully as possible both in the movie theater and in the home theater. THX engineers developed patented technologies to accurately translate the sound from a movie theater environment into the home, correcting the tonal and spatial errors that occur. When the THX mode of the unit is on, three distinct THX technologies are automatically added: Re-Equalization-restores the correct tonal balance for watching a movie in a home environment. These sounds are otherwise mixed to be brighter for a large movie theater. Re-EQ compensates for this and prevents the soundtracks from being overly bright and harsh when played in a home theater. Timbre Matching-filters the information going to the surround speakers so they more closely match the tonal characteristics of the sound coming from the front speakers. This ensures seamless panning between the front and surround speakers. Adaptive Decorrelation-slightly changes one surround channel's time and phase relationship with respect to the other surround channel. This expands the listening position and creates with only two surround speakers the same spacious surround experience as in a movie theater with multiple surround speakers. The unit was required to pass a rigorous series of quality and performance tests, in addition to incorporating the technologies explained above, in order to be THX certified. THX requirements cover every aspect of performance including pre-amplifier and power amplifier performance and operation, and hundreds of other parameters in both the digital and analog domain. Movies which have been encoded in Dolby Digital, DTS, Dolby Pro Logic, stereo and Mono will all benefit from the THX mode when being viewed. The THX mode should only be activated when watching movies which were originally produced for a movie theater environment. THX need not be activated for music, movies made especially for TV, or shows such as sports programming, talk shows, etc. This is because they were originally mixed for a small room environment. The THX logo is a trademark of THX Ltd. which may be registered in some jurisdictions. All rights reserved. THX Surround EX-Dolby DIgital Surround EX is a joint development of Dolby Laboratories and 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 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, 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 www.dolby.com. A list of available DVD software titles encoded with this technology an be found at www.thx.com. Only receiver 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 eocnded. 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. "SURROUND EX™" is a trademark of Dolby Laboratories. Used under authorization. The THX Ultra2 specification provides uncompromised 7.1 channel playback of any multichannel program, whether movie soundtracks or music over the widest possible seating area. There are an additional two processing's for THX Ultra2 as bellow. A.S.A. (Advanced Speaker Array) "ASA" is a proprietary THX technology which processes the sound fed to 2 surround and 2 surround back speakers to provide the optimal surround sound experience. When you set up your home theater system using all eight speaker outputs (Left, Center, Right, Surround Right, Surround Back Right, Surround Back Left, Surround Left and Subwoofer), placing the two Surround Back speakers close together facing the front of the room as shown in the diagram will provide the largest sweet spot. If for practical reasons you have to place the Surround Back speakers apart, you will need to go to the THX Audio Set-up screen and choose the setting that most closely corresponds to the speaker distance, which will re-optimize the surround sound-field. ASA is used in two new surround modes; THX Ultra2 Cinema, THX Music Mode and THX Games mode. B.G.C. (Boundary Gain Compensation) If your chosen listening room layout (for practical or aesthetic reasons) results in most of the listeners being close to the rear wall, the resulting bass level can be sufficiently reinforced by the boundary that the overall sound quality becomes "boomy". THX Ultra2 receivers contain the BGC (Boundary Gain Compensation) feature to provide an improved bass balance. BGC can be selected by choosing "THX Ultra2 Subwoofer-Yes" from the "Boundary Gain Compensation" section of the "THX Audio setup menu". Neural-THX® Surround has been chosen as the official surround sound broadcast format for leading FM/HD and satellite radio and television stations worldwide. Neural-THX Surround delivers the rich envelopment and discrete image detail of surround sound in a format 100% compatible with stereo. Neural-THX Surround draws the brain's attention to sonic details in musical instruments, vocals and ambience that are typically masked by other playback systems. This allows the listener to fully experience the richness and subtleties in recorded performance as never before for both surround encoded material and regular stereo material such as CDs or digital media players.
