Yamaha RX-V690 - Manual (Page 24)

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 depending 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
This program is effective for playback of sources encoded with Dolby Surround.
PRO LOGIC The employment of the digital signal processing system improves crosstalk and transfers the sound source
more smoothly and precisely, compared to the conventional type. A stable movie sound field is recreated.
This program is effective for playback of sources encoded with Dolby Surround.
PRO LOGIC
Enhancing the “Normal” Dolby Pro Logic, the DSP technology simulates the multi-surround speaker
ENHANCED
systems of a 35 mm film theater, thus widening the surrounded-sound field with greater presence.
70 mm MOVIE
This program is effective for playback of sources encoded with Dolby Sorround.
The Yamaha DSP technology is ideally combined with the Dolby Pro Logic to present you incredible
THEATER
listening experience of the 70 mm film movie theater. This program is ideal for precisely reproducing the
sound design of the newest movies. The sound field is made according to the design of the newest 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 Sci-Fi, adventure movies, etc. 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 excessively on the front
side, but the rear surround side produces a dynamic sound expansion. This program is the most suitable for
sports programs encoded with Dolby Surround.
STADIUM
This program gives you long delays between direct sounds and effect sounds, and 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, cozy 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 a 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 decoders 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 surround-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.
