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 analogue 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 cinema 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-V640RDS, 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-V640RDS 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. 64 mixdown is also provided, for enjoying 6-channel input sources from four or five speakers you already have on hand with or without a subwoofer.
High Dynamic Power Capability The RX-V640RDS 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 caused by the copper of the PCB, Speaker output relays, cables and so on, resulting in reduced sound quality.

heavy chassis which is also designed for maximum vibration damping. Anti-Resonance Aluminium-Extruded Heat Sink The large, anti-resonance, aluminiumextruded 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 RXV640RDS, the 12,000F/71V block electrolytic capacitors use lowmagnification foil and are exceptionally high quality. Direct Signal Path Speaker Relays with Gold-Plated Crossover Connection and Shielding Speaker switching is accomplished by RX-V640RDS High Quality Parts relays right in front of the speaker terminals, rather than at the switch position. Extra-Large Low-Impedance This results in a shorter signal path and Transformer minimum output impedance. The large 4.8 kg low-impedance transformer is an important factor in the High Performance Myca Capacitors and RX-V640RDSs extremely stable power Film Capacitors supply. At this level of sound quality, even these small parts make a difference.

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 cinema: 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 centre 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 Programmes One of the main advantages of CINEMA DSP is the large choice of sound field programmes available. The basic programme 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. Centre Graphic Equalizer In addition to the many audio parameters that can be adjusted, the RX-V640RDS provides an even greater degree of sound field control with the inclusion of a Centre Graphic Equalizer. This lets you finely tune the overall balance of the sound field to achieve the optimal imaging for movie sound.

Do not press RDS MODE/FREQ when an RDS station is being received until one or more RDS mode indicators light up on the front panel display. You cannot change the mode if you press this button prior to this. This is because this unit has not finished receiving all of the RDS data on the station. RDS data not offered by the station cannot be selected. This unit cannot utilize the RDS data service if the signal received is not strong enough. In particular, the RT mode requires a large amount of data, so it is possible that the RT mode may not be displayed even if other RDS modes (PS, PTY, etc.) are displayed. Sometimes, RDS data cannot be received in poor reception conditions. If this is the case, press TUNING MODE so that the AUTO indicator disappears from the front panel display. Although this will change the reception mode to monoaural, RDS data may be displayed when you change the display to RDS mode. If the signal strength is weakened by external interference during the reception of an RDS station, the RDS data service may cut off suddenly and.WAIT will appear on the front panel display.

I RT (Radio Text) mode:

Information about the program (such as the title of the song, name of the singer, etc.) on the RDS station being received is displayed using a maximum of 64 alphanumeric characters, including the umlaut symbol. Any other characters used in RT data are displayed with under-bars.

I PCM (Linear PCM)

Linear PCM is a signal format under which an analog audio signal is digitized, recorded and transmitted without using any compression. This is used as a method of recording CDs and DVD audio. The PCM system uses a technique for sampling the size of the analog signal per very small unit of time. Standing for pulse code modulation, the analog signal is encoded as pulses and then modulated for recording.

I Component video signal

I Sampling frequency and number of quantized bits
When digitizing an analog audio signal, the number of times the signal is sampled per second is called the sampling frequency, while the degree of fineness when converting the sound level into a numeric value is called the number of quantized bits. The range of rates that can be played back is determined based on the sampling rate, while the dynamic range representing the sound level difference is determined by the number of quantized bits. In principle, the higher the sampling frequency, the wider the range of frequencies that can be played back, and the higher the number of quantized bits, the more finely the sound level can be reproduced.
With the component video signal system, the video signal is separated into the Y signal for the luminance and the PB and PR signals for the chrominance. Color can be reproduced more faithfully with this system because each of these signals is independent. The component signal is also called the color difference signal because the luminance signal is subtracted from the color signal. A monitor with component input jacks is required in order to use the component signal for output.
