Using Digital Sound Field Processor (Dsp); Brief Overview Of Digital Sound Field Programs - Yamaha DSP-A595 Owner's Manual

USING DIGITAL SOUND FIELD PROCESSOR
This unit 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 are listening to), and adding any desired adjustments.
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 speakers may vary depending on the sound field you are listen-
ing to. This is due to the fact that most of these sound field are re-creation of actual acoustic environments.

FEATURE
Reproduces video discs, video tapes and similar sources which
are Dolby Surround encoded and bear the "DOLBY SUR-
ROUND" logo.
The built-in Dolby Pro Logic Surround decoder or Dolby Digital
decoder precisely reproduces sounds and sound effects of a
source encoded with Dolby Surround. The realization of a
highly efficient decoding process improves crosstalk and
channel separation and makes sound positioning smoother
and more precise.
Reproduces video discs, video tapes and similar sources which
are Dolby Surround encoded and bear the "DOLBY SUR-
ROUND" logo.
This program ideally simulates the multi-surround speaker
systems of the 35 mm film theater. The Dolby Surround
decoding and the digital sound field processing is precisely
performed without altering the original sound orientation. The
surround effects produced by this sound field folds around the
viewer naturally from the rear to the left and right and toward
the screen.
Note: If the main channel sound is considerably altered by
overadjustment of BASS or TREBLE, the relationship with the
rear channels may produce an unnatural effect.
Ideal for reproducing video discs, video tapes and similar
sources which are Dolby Surround encoded and bear the
"DOLBY SURROUND" logo.
This program is ideal for precisely reproducing the sound
design of the newest 70 mm/Dolby Digital multi-track films.
The sound field is made to be similar to that of the newest
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 Sci-Fi,
adventure movies, etc. with considerable presence.
