REFER SERVICING TO QUALIFIED SERVICE PERSONNEL. 11 · Explanation of Graphical Symbols The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert you to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. The exclamation point within an equilateral triangle is intended to alert you to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance. 12 13 WARNING TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS UNIT TO RAIN OR MOISTURE. 14 1 2 3 4 5 Read Instructions ­ All the safety and operating instructions should be read before the product is operated. [. . . ] You can listen to virtual CINEMA DSP by setting "1C REAR LR" in the SET MENU to NON. Sound field processing changes to VIRTUAL CINEMA DSP automatically. 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 5ch 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. 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. (While playing a source) 1 2 Press AMP. Press d to display the information about the input signal. PRESET/CH ­ SELECT + 28 DIGITAL SOUND FIELD PROCESSING (DSP) Understanding sound fields A sound field is defined as the "characteristic sound reflections of a particular space. " 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. INTRODUCTION PREPARATION 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 three 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 three effect speakers to localize the virtual sound sources and fully encompass the listener. BASIC OPERATION 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. Pronounced reflections from all directions emphasize the extension of sounds. The sound field has a great deal of presence, and your virtual seat is near the center, close to the stage. ADVANCED OPERATION ADDITIONAL INFORMATION 2 JAZZ CLUB This is the sound field at stage front in "The Bottom Line", a famous New York jazz club, that seats up to 300 people. Its wide left to right seating arrangement offers a real and vibrant sound. The data for this program was recorded at LA's "hottest" rock club. This program recreates the acoustic environment of a lively disco in the heart of a big city. It is also characterized by a high-energy, "immediate" sound. 3 ROCK CONCERT 4 ENTERTAINMENT/ Disco APPENDIX ENTERTAINMENT/ 5ch Stereo Using this program increases the listening position range. This is a sound field suitable for background music at parties, etc. English 29 CINEMA-DSP Sound design of CINEMA-DSP Filmmakers intend for the dialog to be located right on the screen, the effect sound a little farther back, the music spread even farther back, and the surround sound around the listener. Of course, all of these sounds must be synchronized with the images on the screen. CINEMA-DSP is an upgraded version of YAMAHA DSP specially designed for movie soundtracks. 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. 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.
