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.
CONCERT VIDEO
This program is effective for music videos and gives excellent depth and clarity for vocals. For opera, the
orchestra and stage are ideally recreated, letting you feel as if you were in an actual concert hall.
MONO MOVIE
This program is designed specifically to enhance mono source programs. Compared to a strictly mono
setting, the sound image created in this mode is wider and slightly forward of the speaker pair, lending an
immediacy to the overall sound. It is particularly effective when used with old mono movies, news
broadcasts and dialog.
STADIUM
This program gives you long delays between direct sounds and effect sounds, and extraordinarily
spacious feel of a large stadium.
DISCO
This program recreates the acoustic environment of a lively disco in the heart of a very lively city. The
sound is dense and highly concentrated. It is also characterized by a high-energy, “immediate” sound.
ROCK CONCERT
This program is suitable for rock music. A big, powerful sound is reproduced lively and dynamically.
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.
