Sound field processing changes to VIRTUAL CINEMA DSP automatically. ADDITIONAL INFORMATION y During stereo reproduction, you can display information such as the type, format and sampling frequency of the signal input from the components connected to this unit. Note · This unit is not set in the virtual CINEMA DSP mode even if "1C REAR LR" is set to NON in the following cases: ­ when the 6ch Stereo, DOLBY DIGITAL Normal, Pro Logic Normal, Pro Logic , or DTS Normal program is selected; ­ when the sound effect is turned off; ­ when 6CH INPUT is selected as the input source; ­ when 96-kHz sampling digital signals are input to this unit; ­ when using the test tone; or ­ when connecting the headphones.

" In concert halls and other music venues, we hear early reflections and reverberations as well as the direct sound produced by the artist(s). The variations in the early reflections and other reverberations among the different music venues is what gives each venue its special and recognizable sound quality. YAMAHA sent teams of sound engineers all around the world to measure the sound reflections of famous concert halls and music venues, and collect detailed sound field information such as the direction, strength, range, and delay time of those reflections. Then we stored this enormous amount of data in the ROM chips of this unit. I Recreating a sound field Recreating the sound field of a concert hall or an opera house requires localizing the virtual sound sources in your listening room. The traditional stereo system that uses only two speakers is not capable of recreating a realistic sound field. YAMAHA's DSP requires four effect speakers to recreate sound fields based on the measured sound field data. The processor controls the strength and delay time of the signals output from the four effect speakers to localize the virtual sound sources and fully encompass the listener. Hi-Fi 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. No. 1 Program CONCERT HALL Features A large round concert hall with a rich surround effect. This processing enables this unit to reproduce the immense sound field and surround expression of a Dolby Digitalor DTS-equipped movie theater without sacrificing the clear separation of all channels. Right surround DSP sound field Left surround DSP sound field I Dolby Digital EX/DTS-ES compatible + DSP sound field effect These programs provide you with the maximum experience of the spacious surround effects by adding an extra rear center DSP sound field created from the rear center channel. I Dolby Pro Logic + DSP sound field effect Presence DSP sound field Surround DSP sound field Most movie software has 4-channel (left, center, right, and surround) sound information encoded by Dolby Surround matrix processing and stored on the left and right tracks. These signals are processed by the Dolby Pro Logic decoder. The MOVIE THEATER programs are designed to recreate the spaciousness and delicate nuances of sound that tend to be lost in the encoding and decoding processes. I Dolby Pro Logic Dolby Pro Logic decodes Dolby Surround software into 5 discrete full-range channels (3 channels in front and 2 channels in rear). There are 2 modes; MOVIE for movies and MUSIC for 2-channel audio sources. 32 CINEMA-DSP CINEMA-DSP programs I For movie programs: No. 7 to 9 This unit automatically chooses the appropriate decoder and DSP sound field pattern according to the input signal format.

In this case the program name changes to the corresponding name for 6. 1 channel. · When playing a 6. 1 channel source with the Dolby Digital EX decoder or the DTS-ES compatible decoder turned off, the program name changes to the corresponding name for 5. 1 channel.
