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 were 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 No. 1 to 5: CINEMA-DSP programs (for Audio/Video sources)
These programs use the Dolby Pro Logic decoder, the Dolby Digital decoder or the DTS decoder.
Speaker output: main, center, rear
Note: If the "NONE" position is selected on "1. CENTER SPEAKER" in the SET MENU mode, no sound is output from
the center speaker(s).
Program No. 1 is for reproducing video discs, video tapes and similar sources which are encoded with Dolby Surround (bearing
the "DOLBY SURROUND" or "DOLBY DIGITAL" logo) or encoded with DTS (bearing the "dts" logo).

) The built-in Dolby Pro Logic decoder, the Dolby Digital
decoder or the DTS decoder precisely reproduces sounds
and sound effects of a source encoded with Dolby
Surround or DTS. The realization of a highly efficient
decoding process improves crosstalk and channel
) separation and makes sound positioning smoother and
DIGITAL
more precise.
)
Ideally simulates the multi-surround speaker systems of
the newest film theater. The digital sound field processing
and the Dolby Surround decoding or the DTS decoding
are precisely performed without altering the originally
designed sound orientation. The surround effects
produced by this sound field fold the viewer naturally from
the rear to the left and right and toward the screen.
