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 in. This is due to the fact that most of these sound field recreations are actual acoustic environments.
PROGRAM
FEATURE
This program is used for playback of sources encoded with Dolby Surround.
PRO LOGIC
Dialog is oriented on the screen and effect sounds are effectively located on the left front, right front and
rear surround sides respectively as the movie sound creater designed.
This program is effective not only for playback of sources encoded with Dolby Surround, but also for
sources not encoded with Dolby Surround or TV programs encoded with 2-channel stereo sound. With this
3 STEREO
program, 2-channel stereo sound is converted into 3-channels (left front, center and right front), so dialog
is emphasized on the center position by the use of the center speaker. As no sound is output from the rear
speakers, this program is also effective in a simple Audio/Video system without rear speakers.
HALL
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.
ROCK
This program is ideally suited for rock music. You will experience a very dynamic or lively sound field.
USING DIGITAL SOUND FIELD PROCESSOR (DSP)
This unit incorporates a sophisticated 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.
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 a corresponding DSP
program.
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.
