SOUND FIELD PROGRAM

This unit incorporates a sophisticated, multi-program digital sound field processor. 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 sound field program (this will, of course, depend on what you are listening to) and adding any desired adjustments.

The operation of built-in decoders (Dolby Pro Logic, Dolby Digital and DTS) can be controlled by selecting a corresponding DSP program incorporating the combined operation of YAMAHA DSP and Dolby Surround, Dolby Digital or DTS.

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.
