" In concert halls and other music venues, we hear early reflections and reverberations as well as the direct sound produced by the artist(s). CINEMA-DSP integrates the DTS, Dolby Digital, and Dolby Pro Logic surround sound technologies with YAMAHA DSP sound field programs to provide a surround sound field. It recreates comprehensive movie sound design in your audio room. In CINEMA-DSP sound field programs, YAMAHA's exclusive DSP processing is added to the Main left and right, and Center channels, so the listener can enjoy realistic dialogue, depth of sound, smooth transition between sound sources, and a surround sound field that goes beyond the screen. When a DTS or Dolby Digital signal is detected, the CINEMA-DSP sound field processor automatically chooses the most suitable sound field program for that signal. L SURROUND SOUND FIELD PRESENCE SOUND FIELD DIALOG EFFECT MUSIC R SURROUND SOUND FIELD In addition to the DSP, this unit is equipped with a variety of precise decoders; Dolby Pro Logic decoder for Dolby Surround sources, Dolby Pro Logic II decoder for Dolby Surround and 2-channel sources, Dolby Digital/DTS decoder for multi-channel sources and Dolby Digital EX or DTS-ES decoder for adding a rear center channel. You can select CINEMA-DSP programs to optimize these decoders and the DSP sound patterns depending on the input source. CINEMA-DSP Programs 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 recreations of actual acoustic environments. Select the DSP program that you feel sounds best regardless of the name and description given for it below. I For audio-video sources: No. 4 Program ENTERTAINMENT/ Game MUSIC VIDEO Features This program adds a deep and spatial feeling to video game sounds. 5 This program lends an enthusiastic atmosphere to the sound, giving you the feeling you are at an actual jazz or rock concert. This program is provided for reproducing monaural video sources (such as old movies). The program produces the optimum reverberation to create sound depth using only the presence sound field. Though the presence sound field is relatively narrow, the surround sound field employs the sound environment of a large concert hall.
