The employment of the digital signal processing system improves crosstalk and transfers the sound source more smoothly and precisely, compared to the conventional type. A stable movie sound field is recreated. This program is effective for playback of sources encoded with the Dolby Surround. Enhancing the "Normal" Dolby Pro Logic, the DSP technology simulates the multi-surround speaker systems of a 35 mm film theater, thus widening the surrounded-sound field with greater presence. This program is effective for music videos and gives excellent depth and clarity for vocals. For opera, the orchestra and stage are ideally recreated, letting you feel as if you were in an actual concert hall. This program is designed specifically to enhance mono source programs. Compared to a strictly mono setting, the sound image created in this mode is wider and slightly forward of the speaker pair, lending an immediacy to the overall sound. It is particularly effective when used with old mono movies, news broadcasts and dialog. This program is suitable for rock music. A big, powerful sound is reproduced lively and dynamically. In this program, the center seems even more deeply behind the front speaker pair, creating an expansive, large hall ambience. ENHANCED CONCERT VIDEO MONO MOVIE ROCK CONCERT CONCERT HALL 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. ÷ 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. Description of YDolby 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). 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.
