USING THE AV-S7
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 DSP program. 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 because
most of these sound field recreations are actual
acoustic environments.
FEATURE
This program is used for playing 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 is also used for playing 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 effective for music videos and gives excellent depth and clarity for vocals.
For opera, the orchestra and stage are ideally recreated, making you feel as if you were in an
actual concert hall.
This program is ideal for enjoying sports programs which take place in arenas, indoor
stadiums, or other venues.
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.
