The front effect channel signals, unique to Yamaha CINEMA DSP, are mixed with the main channel signals to achieve more precise separation of dialogue, music and effects on the front sound stage and a superior sense of presence as compared to other systems.
are smaller (2/3 previous types), so signal paths are shorter and there is more space for the large power supply components. Digital interference is reduced and impedance is lower as well. Accurate Touch Volume Control No one expects more from a volume
control than up and down except Yamaha. We decided that controlling the volume could be made both easier and more accurate, and the result is the Accurate Touch Volume Control. It lets you make delicate adjustments within a narrow range, yet enables you to move to very high or low levels more quickly.
Its extreme accuracy is due to a highsignal-resolution analog design in conjunction with an ultra-precise digital control circuit (Yamaha original YAC-520 LSI). The wide control range extends from 0dB to 99dB, with narrow 0.5dB steps throughout the entire range for delicate control, even at low volumes.
Brief Guide to Movie Sound Formats
Dolby Pro-Logic Dolby Labs basic 4-channel format, widely used in ordinary theaters and for home videos. Dolby Pro Logic II Improved version of Dolby Pro-Logic for music and movies. With a more intelligent matrix decoder, it is suitable for both stereo and surround-encoded sources. It offers bass management as well as the option of incorporating width, dimension and panorama controls. Dolby Digital The most popular 5.1-channel home theater sound system. An improvement over Dolby Pro-Logic in that it offers: 1) Full frequency response in all channels (3Hz 20kHz), 2) discrete surround channels, and 3) a separate track for bass only, called the Low Frequency Effects channel. Dolby Digital EX Dolby's latest surround format, this is Dolby Digital with an added center rear channel. The rear center channel is actually matrixed into the two rear channels, and is extracted upon playback. (Formerly called Dolby Digital Surround EX, or Dolby Digital Matrix 6.1.) DTS Digital Surround The basic DTS 5.1 channel sound format. Uses a higher data rate than Dolby Digital. DTS-ES Matrix 6.1 In this format, the back surround channel is matrix encoded into the left and right surround channels. For playback, the three channels are separately decoded. DTS-ES Discrete 6.1 DTS-ES uses its large bandwidth to provide a fully discrete rear center channel, as opposed to a matrixed one. DTS Neo:6 Provides 5.1 or 6.1 channels of matrix decoding from stereo matrix material. Also decodes Extended Surround matrix soundtracks and has a Music mode to expand stereo non-matrix recordings to 5.1 or 6.1 channels.

High Current Amplification Achieves Low Impedance/ High Current Power from Input to Output.
The Importance of High Current Although power rating is often the first thing customers look at in a receiver, high power output does not necessarily mean good sound. High current level is a much more important factor. Yamaha receivers has always had fairly high current levels, but with the RX-V640, we have further improved this performance. What It Does In brief, Yamaha High Current Amplification achieves low impedance, high current power from input (power supply circuit) to output (speaker terminals). This drives the speakers much more smoothly and dynamically, for better sound from all sources, including 2channel audio. Specific Improvements The first problem to be overcome was the difference in voltage that ordinary receivers suffer between the power supply and amplifier circuits, caused by current
fluctuations. This was solved by using custom-made, high-grade block electrolytic capacitors and a copper grip for one-point grounding. Another current drop is generally seen between the amplifier circuit and the speaker terminals, caused by the cables, speaker output relays, copper circuit boards, and so on. To increase current here, we used an extra-large, low-impedance transformer and gold-plated speaker relay contacts. 6-Channel High Power, Discrete Amplifier Configuration The RX-V640 will deliver as much as 85W of power to each of six channels (two main, two rear, one center and one rear center). This is more than enough to fill even the largest rooms with vibrant music and Richter-scale sound effects. 6-4 mixdown is also provided, for enjoying 6channel input sources from four or five speakers you already have on hand with or without a subwoofer.
High Dynamic Power Capability The RX-V640 is capable of delivering large amounts of reserve power for accurate reproduction of the high energy peaks that are especially prevalent in digital audio sources. This emphasizes the musics dynamic qualities and provides a sharper sound image. Linear Damping (Main L/R Channels) Level variations due to high amp impedance tend to reduce an amplifiers damping factor, and frequency variations cause it to fluctuate. This circuit cancels the effect of these variations, maintaining a high, stable damping factor, for superior articulation of all sounds and better frequency response. Anti-Resonance ToP-ART Base Supporting the heavy heat sinks and circuit board is Yamahas ToP-ART base, which has exceptional anti-resonance and damping characteristics. Beneath this base is the bottom of power amplifier, part of the

High Current Amplification Principle
The voltage (A) of Block Electrolytic Capacitors and voltage (B) of Power Transistor Collector should be ideally at the same level. However, when the current become large, there will be a big difference in the level of each voltages. There is also a level difference between Output of the Power Amplifier (C) and Speaker Terminals (D), which is reflected by coppers of PCB, Speaker out put relays, cables and so on, resulting damaging the sound quality.

heavy chassis which is also designed for maximum vibration damping. Anti-Resonance Aluminum-Extruded Heat Sink The large, anti-resonance, aluminumextruded heat sink is located on the base frame with the power amplifier circuit boards to prevent interference with the preamplifier and digital processing sections. The power block is equipped with a fan, but it is only used for extreme heat build-up and is not activated during normal operation, preventing the occurrence of even the slightest unwanted noise. Wide-Range Frequency Response for DVD-Audio and SACD With an extremely wide frequency range of 10 to 100,000Hz, this receiver is capable of delivering the full potential of the new digital audio sources DVD-Audio and SACD. Optimum Space Utilization The use of highly integrated LSIs allows an interior design that maximizes power and sound quality by positioning all the digital processors and related circuitry in one small area. This leaves most of the space open for the power amplifier components: transformers, capacitors, heat sink and so on. This means that these parts can be much larger than usual for greater power, that they can be separated for minimum chance of interference, and that circuits can be arranged in straight lines for maximum signal purity. For example, the tone control circuit layout is straighter and shorter than ever. Finest Parts Used Throughout In order to realize the goals of massive power and superlative sound quality, Yamaha technicians completely reevaluated all the parts used in previous receivers. As a result, many were replaced with more expensive or customdesigned units.

Extra-Large Custom-Made Block Electrolytic Capacitors Developed specifically for the RX-V640, the 12,000F block electrolytic capacitors use low-magnification foil and are exceptionally high quality. Direct Signal Path Speaker Relays with Gold-Plated Crossover Connection and Shielding Speaker switching is accomplished by relays right in front of the speaker terminals, rather than at the switch position. This results in a shorter signal path and minimum output impedance. High Performance Myca Capacitors and Film Capacitors At this level of sound quality, even these small parts make a difference. The high precision FE mica and metallic mylar film capacitors use polypropylene material and are the highest performance types on the market.

No Other Surround Sound System Can Match for Rich, Detailed, Realistic Sound.
Going Beyond Conventional MultiChannel Systems Conventional 5.1-channel/6.1-channel audio reproduction systems base their sound on Dolby Digital and DTS decoding, using matrix and steering technologies to create surround sound effects. Yamaha CINEMA DSP is much more advanced, actually creating richly realized independent sound fields that merge to envelop you in an unmatched surround sound experience. With dialogue, music and effects from the presence (front), rear and rear sound fields, you will hear sound with highly accurate localization, smooth movement, exceptional clarity and richness, and startlingly realistic presence. It will seem as if the walls of your room have disappeared and you are in the middle of your own immense theater!
Quad-Field and Tri-Field CINEMA DSP Tri-Field CINEMA DSP projects three sound fields into the home theater: a Presence sound field in the front and two Surround sound fields in the left rear and right rear, resulting in a powerfully realistic three-dimensional soundscape. And now Yamaha also offers Quad-Field CINEMA DSP. It adds an additional rear center sound field to the Tri-Field system, in order to enjoy the new 6.1-channel formats, Dolby Digital EX and DTS-ES. CINEMA DSP Programs One of the main advantages of CINEMA DSP is the large choice of sound field programs available. The basic program for movies is Enhanced, which greatly improves the sound of the surround fields. The "largest" of these sound

fields is Spectacle, which recreates the open feeling of large-scale, epic motion pictures. The Sci-Fi is designed to reproduce all the complex, dynamic sounds of space/science fiction movies. Adventure and General are also included. Center Graphic Equalizer In addition to the many audio parameters that can be adjusted, the RX-V640 provides an even greater degree of sound field control with the inclusion of a Center Graphic Equalizer. This lets you finely tune the overall balance of the sound field to achieve the optimal imaging for movie sound.

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.
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. YAMAHAs 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. 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. 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 ideal program for lively, dynamic rock music. The data for this program was recorded at LAs hottest rock club. The listeners virtual seat is at the center-left of the hall. This program recreates the acoustic environment of a lively disco in the heart of a big city. The sound is dense and highly concentrated. It is also characterized by a high-energy, immediate sound. Using this program increases the listening position range. This is a sound field suitable for background music at parties, etc.

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. It recreates comprehensive movie sound design in your audio room. In CINEMA-DSP sound field programs, YAMAHAs 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.

GLOSSARY

I Dolby Surround
Dolby Surround uses a 4 channel analog recording system to reproduce realistic and dynamic sound effects: 2 main left and right channels (stereo), a center channel for dialog (monaural), and a rear channel for special sound effects (monaural). The rear channel reproduces sound within a narrow frequency range. Dolby Surround is widely used with nearly all video tapes and laser discs, and in many TV and cable broadcasts as well. The Dolby Pro Logic decoder built into this unit employs a digital signal processing system that automatically stabilizes the volume on each channel to enhance moving sound effects and directionality.
I DTS (Digital Theater Systems) Digital Surround
DTS digital surround was developed to replace the analog soundtracks of movies with a 6-channel digital sound track, and is now rapidly gaining popularity in movie theaters around the world. Digital Theater Systems Inc. has developed a home theater system so that you can enjoy the depth of sound and natural spatial representation of DTS digital surround in your home. This system produces practically distortion-free 6-channel sound (technically, a left, right and center channels, 2 rear channels, plus an LFE 0.1 channel as a subwoofer, for a total of 5.1 channels). The unit incorporates DTS-ES decoder that enables 6.1channel reproduction by adding the rear center channel to existing 5.1-channel format.

I Dolby Digital

Dolby Digital is a digital surround sound system that gives you completely independent multi-channel audio. With 3 front channels (left, center, and right), and 2 rear stereo channels, Dolby Digital provides 5 full-range audio channels. With an additional channel especially for bass effects, called LFE (low frequency effect), the system has a total of 5.1 channels (LFE is counted as 0.1 channel). By using 2-channel stereo for the rear speakers, more accurate moving sound effects and surround sound environment are possible than with Dolby Surround. The wide dynamic range (from maximum to minimum volume) reproduced by the 5 full-range channels and the precise sound orientation generated using digital sound processing provide listeners with previously unheard of excitement and realism. With this unit, any sound environment from monaural up to a 5.1-channel configuration can be freely selected for your enjoyment. Dolby Digital EX creates 6 full-bandwidth output channels from 5.1-channel sources. This is done using a matrix decoder that derives 3 surround channels from the 2 in the original recording. For the best results, Dolby Digital EX should be used with movie sound tracks recorded with Dolby Digital Surround EX. With this additional channel, you can experience more dynamic and realistic moving sound especially with scenes with flyover and fly-around effects.

I Neo:6

Neo:6 decodes the conventional 2-channel sources for 6 channel playback by a specific decoder. It enables playback with the full-range of channels with higher separation just like digital discrete signal playback. Two modes are available; Music mode for playing music sources and Cinema mode for movies.

I LFE 0.1 channel

This channel is for the reproduction of low bass signals. The frequency range for this channel is 20 Hz to 120 Hz. This channel is counted as 0.1 because it only enforces a low frequency range compared to the full-range reproduced by the other 5 channels in a Dolby Digital or DTS 5.1 channel systems.

I CINEMA DSP

I Dolby Pro Logic II
Dolby Pro Logic II is an improved technique used to decode vast numbers of existing Dolby Surround software. This new technology enables a discrete 5channel playback with 2 main left and right channels, 1 center channel, and 2 rear left and right channels (instead of only 1 rear channel for conventional Pro Logic technology). A music mode is also available for 2-channel sources in addition to the movie mode.
