Description of Each Sound Field Program
The following list gives brief descriptions of the sound fields produced by each of the DSP programs. Keep in mind
that most of these are precise digital recreations of actual acoustic environments. The data for them was recorded at
the locations described using sophisticated sound field measurement equipment.
Note:
The channel level balance between the left rear effect speaker and the right rear effect speaker may vary de-
pending on the sound field you are listening to. This is due to the fact that most of these sound field recreations
are actual acoustic environments.
PROGRAM
FEATURE
PRO LOGIC
This program is effective for playback of sources encoded with Dolby Surround. The employ-
ment of the digital signal processing system reduces crosstalk and transfers the sound
source more smoothly and precisely, compared to conventional types. A stable movie sound
field is recreated.
PRO LOGIC ENHANCED
This program is effective for playback of sources encoded with Dolby Surround. Enhancing
the “Normal” Dolby Pro Logic, the DSP technology simulates the multi-surround speaker
systems of a 35 mm film theater, thus widening the surround-sound field with greater
presence.
70 mm MOVIE THEATER
This program is effective for playback of sources encoded with Dolby Surround.
The Yamaha DSP technology is ideally combined with the Dolby Pro Logic to present you the
incredible listening experience of the 70 mm movie theater. This program is ideal for pre-
cisely reproducing the sound design of the newest movies. The sound field is made accord-
ing to the design of the latest movie theaters, so the reverberations of the sound field itself
are restrained as much as possible. The three-dimensional feeling of the sound field is
emphasized and dialog is precisely oriented on the screen. You can enjoy watching science-
fiction, action, and adventure movies with this program.
TV THEATER
This program is suitable for dramas, variety or music programs, etc. Much surround effect
can be gained for stereo sources.
SPORTS
This program is furnished with a tight sound field in which the sound will not spread exces-
sively on the front side, but the rear surround produces a dynamic sound expansion. This
program is most suitable for sports programs encoded with Dolby Surround
STADIUM
This program gives you long delays between direct sounds and effect sounds, and the
extraordinarily spacious feel of a large stadium.
ROCK CONCERT
This program is suitable for rock music. A big, powerful sound is reproduced lively and
dynamically.
JAZZ CLUB
This is a small, cosy jazz club with a low ceiling. The sound is very close and intimate.
CHURCH
This program recreates the acoustic environment of a modern church with a high pointed
dome and columns along the sides. This interior produces very few primary reflections.
CONCERT HALL
In this program, the center seems deep behind the front speaker pair, creating an expansive,
large hall ambience.
Description of Dolby Pro Logic Surround
DOLBY PRO LOGIC SURROUND:
This unit
employs the Dolby Pro Logic Surround system. This
system is similar to professional Dolby Stereo decod-
ers used in movie theaters.
By employing a four-channel system, the Dolby Pro
Logic Surround system divides the input signals into
four levels: the left and right main channels, the center
channel (to characterize dialog), and the rear sur-
round-sound channels (to characterize sound effects,
background noise and other ambient noise).
Dolby Surround is encoded on the sound track of
commercially available video cassettes and video
discs as well. When you play a source encoded with
Dolby Surround on your home video system, the
Dolby Pro Logic Surround system in this unit decodes
the signal and feeds the surround-sound effects.
The Dolby Pro Logic Surround mode may not be
always effective on video sources not encoded with
Dolby Surround.
