Description of Each Sound Field Program
FEATURE
This program is effective for playback of sources encoded with the Dolby Surround.
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 the 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 surrounded-sound field with greater presence.
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.
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.
This program is suitable for rock music. A big, powerful sound is reproduced lively and dynamically.
In this program, the center seems even more deeply behind the front speaker pair, creating an
expansive, large hall ambience.

Notes on Operation of Sound Field Programs
÷ In the CONCERT VIDEO, MONO MOVIE, ROCK
CONCERT and CONCERT HALL modes, no sound is
heard from the center speaker.
÷ When a monaural sound source is played in the DOLBY
PRO LOGIC or ENHANCED mode, no sound is heard
from the front speakers and the rear speakers. Sound is
heard only from the center speaker. However, if the
center mode is in the PHANTOM, the front speakers
output the sound of the center speaker.
÷ When this unit is in the Dolby Pro Logic Surround mode, if
the main-source sound is considerably altered by
overadjustment of the BASS or TREBLE controls, the
relationship between the center and rear channels may
produce an unnatural effect.
Description of ŸDolby 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 mode on 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.
