English Dolby Pro Logic Surround The Dolby Pro Logic Surround Decoder program lets you experience the dramatic realism and impact of Dolby Surround movie theater sound in your own home. Dolby Pro Logic gets its name from its professional-grade steering logic circuitry, which provides greater effective channel separation for a much higher degree of realism than the "passive" Dolby Surround circuits found in today's typical home audio/video equipment. Dolby Pro Logic Surround provides a true center channel, so that there are four independent channels, unlike passive Dolby Surround, which has in effect only three channels: left, right, and rear. This center channel allows listeners seated in even less-than-ideal positions to hear the dialog originating from the action on the screen while experiencing good stereo imaging. This Dolby Pro Logic Surround Decoder employs a digital signal processing system. This system improves the stability of sound at each channel and crosstalk between channels, so that positioning of sounds around the room is more accurate compared with conventional analog signal processing systems. In addition, this unit features a built-in automatic input balance control. This always assures you the best performance without manual adjustment. Manufactured under license from Dolby Laboratories Licensing Corporation. Additionally licensed under one or more of the following patents: U.S. number 3,950,590; Canadian numbers 1,004,603 and 1,037,877. "Dolby", "Pro Logic", and the double-D symbol are trademarks of Dolby Laboratories Licensing Corporation. Dolby Pro Logic Surround + DSP You can also enjoy Dolby Pro Logic with two modes of Digital Sound Field Processing. These combinations expand the surround effect of Dolby Pro Logic. One is the sound field program "Enhanced DOLBY PRO LOGIC SURROUND", which recreates the surround effect of the 35 mm film movie theater. The other is the combination of Dolby Pro Logic and the sound field program "MOVIE THEATER", which recreates the listening experience of a 70 mm film theater. The YAMAHA "CINEMA DSP" logo indicates these programs created by the combination of Dolby Pro Logic and YAMAHA DSP technology. Directional Enhancement Circuit + DSP The YAMAHA directional enhancement (DIR. ENHANCEMENT) circuit expands and focuses the digital sound field. This effect puts you in the midst of the action, while centering and focusing your attention to the screen. This circuit is available on Sound Field programs "TV THEATER 1", "TV THEATER 2", "CONCERT VIDEO" and "VIDEO THEATER". 5
