Notes on Operation of Sound Field Programs

●In the CONCERT VIDEO, MONO MOVIE, ROCK CONCERT and CONCERT HALL modes, no sound is heard from the center speaker.

●When a monaural sound source is played in the DOLBY PRO LOGIC or ENHANCED mode, no sound is heard from the front speakers and the rear speakers. Sound is heard only from the center speaker. However, if the center mode is in the PHANTOM, the front speakers output the sound of the center speaker.

Description of Dolby Pro Logic Surround

DOLBY PRO LOGIC SURROUND: This unit employs the Dolby Pro Logic Surround system. This system is similar to professional Dolby Stereo decoders used in movie theaters. By employing a four-channel system, the Dolby Pro Logic Surround system divides the input signals into four levels: the left and right main channels, the center channel (to characterize dialog), and the rear surround-sound channels (to characterize sound effects, background noise and other ambient noise).

●If you connect an external amplifier to this unit, see if it has built-in surround sound or ambience circuitry. If it does, then be sure that the surround or ambience circuitry on that amplifier is off while you are using the digital sound field processor’s Dolby Pro Logic Surround decoding function.

●When this unit is in the Dolby Pro Logic Surround mode, if the main-source sound is considerably altered by overadjustment of the BASS or TREBLE controls, the relationship between the center and rear channels may produce an unnatural effect.

Dolby Surround is encoded on the sound track of commercially available video cassettes and video discs as well. When you play a source encoded with Dolby Surround on your home video system, the Dolby Pro Logic Surround mode on this unit decodes the signal and feeds the surround-sound effects.

The Dolby Pro Logic Surround mode may not be always effective on video sources not encoded with Dolby Surround.
