Note:
THX Surround EX can only be selected if the surround back speakers are connected.
THX Surround EX
“THX Surround EX - Dolby Digital Surround EX” is a joint development of Dolby Laboratories and the THX divi- sion 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, 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 localiza- tion than ever before.
When released to the home consumer market, movies that were created using the Dolby Digital Surround EX technology, may have a note to that effect on the packaging. A list of movies created using this technol- ogy can be found on the Dolby web site at http:// www.dolby.com <http://www.dolby.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 will be program dependent and may or may not be very pleasing depending on the particu- lar soundtrack and the tastes of the individual lis- tener.
Action
This mode is designed for movie soundtracks that stress special effect sounds and surround effects. In addition to strengthening the low frequency ranges for the front left, front right, and surround speakers, it also increases the surround levels. Resonance is also cut for a movie- theater feeling and increased enjoyment.
Musical
This mode is designed for watching musicals and movie soundtracks where importance is placed on the music. By slightly increasing the mid to high frequency ranges from the center speaker, the vocals from the screen seem highlighted for added listening pleasure. This mode is optimum for playing software that stresses mu- sic, environmental sounds, and the front image.
Pro Logic/3 Stereo (Dolby Pro Logic/3 Stereo)
This mode is for listening to recordings with Dolby sur- round, which consists of four channels (left, right, cen- ter, and monaural surround) and emphasizes the cen- ter channel. Dolby Pro Logic is very effective for pan- ning music, conversation, and three-dimensional sound movement output from the three front channels. It also simulates the atmosphere and surround effects of the sound reflected from the side and rear walls of the theater. Select this listening mode when you play a VHS, VHS hi-fi, LD, or DVD video that has the 
mark.
If no surround speakers are connected, then the sur- round sound is divided and output from the front left and right channels.(3 Stereo)
Pro Logic THX (Dolby Pro Logic THX)
This mode is the same as the Dolby Pro Logic listening
mode with the THX effects added as well. Select this mode when listening to movies that were encoded us- ing Dolby Pro Logic.
Pro Logic Action (Dolby Pro Logic Action)
When listening to movies using the Dolby Pro Logic, this mode allows you to further enhance the cinematic quality by adding processing that emphasizes the sounds of the action special effects.
Pro Logic Musical (Dolby Pro Logic Musical)
When listening to music using the Dolby Pro Logic, this mode allows you to further enhance the sound quality by adding processing that emphasizes the musical ef- fects.
Mono Movie
This mode is suitable for playing back monaural record- ing such as old movie soundtracks. The center channel delivers the unprocessed original sound, whereas the other channels deliver the center-channel sound pro- cessed with the appropriate reverberation. This allows you to enjoy monaural sound with the atmosphere of a movie theater.
T-D (Theater-Dimensional)
For the best enjoyment of your home theater, it is rec- ommended that you have at least front left and right speakers, a center speaker, and surround left and right speakers. However, if you do only have front left and right speakers, you can enjoy multichannel audio by using this mode.
This mode controls the characteristics of the sound that reaches each ear to reproduce a multi-speaker setup. To receive the full effect, there is an optimum listening position (sweet spot). Refer to the explanation of the listening angle. In addition, if the reflective sound com- ponents are large, it may be difficult to achieve the desired result, so be sure to set up your system and lis- tening position to minimize reflective sound.
Enhanced 7
Enhanced 7 intends to reproduce a natural surround environment by using 7-channel speakers. The sound effects moving smoothly toward the surround back. This mode is good for music and TV sports programs.
Orchestra
This mode is appropriate for classical and opera music. The center channel is cut and the surround channels are emphasized to widen the stereo image. It will simu- late the natural reverberation that is created in large halls.
TV Logic
This mode gives realistic acoustics to TV programs that are aired from TV studios. It enhances the entire sur- round sound and clarity of the conversation.
Unplugged
This mode is suitable for acoustical instrumental sounds, vocals, and jazz music. By emphasizing the front stereo image, it will simulate the acoustics that you would ex- perience in front of the stage.
Studio-Mix
This mode is for rock and popular music. The lively sounds are enhanced for a powerful acoustic image that simulates the feeling of being in a club or rock con- cert.
All Ch Stereo
This mode is designed for playing background music. The front, surround, and surround back channels cre- ate a stereo image that encompasses the entire area. 39
