GLOSSARY

■THX MUSIC MODE

For the replay of multi-channel music the THX Music Mode should be selected. In this mode THX ASA processing is applied to the surround channels of all 5.1 encoded music sources such as DTS, and Dolby Digital to provide a wide stable rear soundstage. This mode is to be used with multi-channel music sources such as DTS 5.1 music and Dolby Digital 5.1 music.

■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 ‘On’ from the ‘BGC’ section of the ‘THX Set’ setup menu.

■THX Ultra2

Before any home theatre component can be THX Ultra2 certified, it must pass a rigorous series of quality and performance tests. Only then can a product feature the THX Ultra2 logo, which is your guarantee that the Home Theatre products you purchase will give you superb performance for many years to come. The THX Ultra2 specification provides uncompromised eight-channel playback of any multi-channel program, whether movie soundtracks or music over the widest possible seating area. In addition, all Ultra2 controllers and receivers incorporate video switching capable of handling all wide- bandwidth sources, including HDTV and progressive scan DVD, without degrading the picture.

■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 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 can 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 encoded. In such case the information delivered to the Surround Back channel is program dependent and may or may not be very pleasing depending on the particular soundtrack and the tastes of the individual listener.

■ITU-R

ITU-R is the radio communication sector of the ITU (International Telecommunication Union). ITU-R recommends a standard speaker placement which is used in many critical listening rooms, especially for mastering purposes.
