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. [. . . ] Virtual rear center speaker does not work for 5. 1 channel sources. This setting produces 6-channel playback of the input source using the Matrix 6. 1 decoder. The virtual rear center speaker can be used when playing a 5. 1-channel source. Virtual rear center speaker does not work in this setting. Notes · This feature is not available when 6CH INPUT is selected or 96-kHz sampling digital signals are input to this unit. · The sound of LFE channel will be mixed and output from the headphone. I Normal stereo reproduction 1 Matrix6. 1: Press STEREO to turn off the sound effect for normal stereo reproduction. Press STEREO again to turn the sound effect back on. STEREO STEREO OFF: or EFFECT ENTER EFFECT Front panel Remote control Notes · The setting becomes AUTO once this unit turns into standby mode. · Some Dolby Digital Surround EX or DTS ES software may not contain the signal that is necessary for this unit to switch to the Matrix 6. 1 decoding mode. To turn on the Matrix 6. 1 decoder when playing such a source, select "Matrix6. 1". Notes · If you turn off the sound effects, no sound is output from the center speaker, rear speakers. · If you turn off the sound effects while a Dolby Digital or DTS signal is being output, the dynamic range of the signal is automatically compressed and the sounds of the center and rear speaker channels are mixed and output from the main speakers. · The volume may be greatly reduced when you turn off the sound effects or if you set "4 D. · The sound of LFE channel will be directed to the main left and right or the subwoofer (or both) channels depending on the setting of "1D BASS" on the SET MENU. I Virtual CINEMA DSP With Virtual CINEMA DSP, you can enjoy all DSP programs without rear speakers. It creates virtual speakers to reproduce a natural sound field. 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.
