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

 

 

 

 

 

 

 

 

 

 

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 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.
