USING DIGITAL SOUND FIELD PROCESSOR (DSP)
USING DIGITAL SOUND FIELD PROCESSOR (DSP)
This system incorporates a sophisticated, multi-
program digital sound field processor. The processor
allows you to electronically expand and change the
shape of the audio sound field from both audio and
video sources, creating a theater-like experience in
your listening room. You can create an excellent audio
sound field by selecting a suitable sound field program
(this will, of course, depend on what you will be
listening to), and adding desired adjustments.
In addition, this unit incorporates a Dolby Pro Logic
Surround decoder for multi-channel sound reproduction
of sources encoded with Dolby Surround.
The operation of the Dolby Pro Logic Surround decoder
can be controlled by selecting the DSP program,
PRO LOGIC or PRO LOGIC ENHANCED.
Brief Overview of Digital Sound Field
Programs
The following list gives you a brief description 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 these sound fields was recorded at actual locations
using sophisticated sound field measurement
equipment.
Note
The channel level balance between the left and
right rear effect speakers 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.
FEATURE
This program is used for playback of sources encoded with Dolby Surround.
The application of a sophisticated digital signal processing system reduces crosstalk and
directs or steers the sound source more smoothly and precisely, as compared to conventional
types.
This program is also used 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 movie theater. This effect creates a wide surround sound field,
and expands the sound stage with an improved presence image. This program is used for
musical based movies, as well as drama and comedy based movies.
This program gives you long delays between direct sounds and effect sounds, and
extraordinarily spacious feel of a large stadium.
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.
In this program, the center will appear to be deep behind the main speakers, creating an
expansive large hall ambience. Orchestra and opera music are suited for this sound field.
This program is ideally suited for rock music. You will experience a very dynamic or lively
sound field.
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 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.
