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 (Dobly Pro Logic and Dolby Digital) 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.

For movie or audio/video sources (Program No. 1 to No. 5: CINEMA DSP

programs)

FEATURES

The built-in Dolby Pro Logic decoder or

Dolby Digital decoder precisely reproduces

the sound and effect of a source encoded with

Dolby Surround or Dolby Digital.

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 or

Dolby Digital 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.
