Advanced Operation; Sound Field Program - Yamaha DSP-A5 Owner's Manual

ADVANCED OPERATION

This unit incorporates a sophisticated, multi-program digital sound field processor (DSP). This 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 outstanding audio sound by selecting a suitable DSP program (this
will, of course, depend on what you are listening to).
When you select a CINEMA DSP program, one of the built-in decoders (Dolby Pro Logic, Dolby Digital and DTS) is turned
on according to which type of signals the source being played contains.
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 re-creations of actual acoustic environments.
• The input source given in the following table for programs 4 through 8 indicates that input source which each program
is best suited for.
• Select the DSP program that you feel sounds best regardless of the name and description given for it below.

FEATURES
The built-in Dolby Pro Logic decoder, Dolby
Digital decoder or DTS decoder precisely
reproduces the sound and effect of a source
encoded with Dolby Surround, Dolby Digital
or DTS.
The realization of a highly efficient decoding
process improves cross talk and channel
separation, and makes sound positioning
smoother and more precise.
In this program, the digital sound field
processor is not turned on.
This program ideally simulates the multi-
surround speaker systems of the 35 mm-film
movie theater. Dolby Pro Logic decoding,
Dolby Digital decoding or DTS decoding and
digital sound field processing are precisely
performed without altering the original sound
orientation.
The surround effect produced by the sound
field folds around the viewer naturally from
the rear to the right and left, and toward the
screen.
