Input Setup
THX Surround EX
“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,
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.
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 technology 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 particular soundtrack and the
tastes of the individual listener.
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 music, environmental sounds, and the front image.
Pro Logic/3 Stereo (Dolby Pro Logic/3 Stereo)
This mode is for listening to recordings with Dolby surround,
which consists of four channels (left, right, center, and monaural
surround) and emphasizes the center channel. Dolby Pro Logic is
very effective for panning 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 surround 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 using 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 effects.
Mono Movie
This mode is suitable for playing back monaural recording such as
old movie soundtracks. The center channel delivers the
unprocessed original sound, whereas the other channels deliver the
center-channel sound processed 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 recommended
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 components are large, it may be difficult to achieve the
desired result, so be sure to set up your system and listening
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 simulate 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 surround 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 experience 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 concert.
All Ch Stereo
This mode is designed for playing background music. The front,
surround, and surround back channels create a stereo image that
encompasses the entire area.
