POWERFUL HOME THEATER RECEIVER
The RX-V640 is a full-featured home theater receiver ready for all formats and for custom installation. Major features include 6-channel discrete amplification (85W x6), Yamaha's Digital ToP-ART design concept, Quad-Field CINEMA DSP, 24 surround program, SILENT CINEMA, and a preset remote control. It delivers high power to six channels and provides DTS ES Discrete 6.1, Neo:6, and DTS ES Matrix 6.1 decoding as well as Dolby Digital EX and Dolby Pro Logic II decoding.
Digital ToP-ART (Total Purity Audio Reproduction Technology) is the name Yamaha has given to a design philosophy whose goal is to maximize signal purity.
ADVANCED DECODING CIRCUITRY
Yamaha's exclusive YSS-938 32-bit floating point quantization LSI. The decoding circuitry performs Dolby Pro Logic II, Dolby Digital Surround, DTS-ES (DTS-ES Matrix 6.1 and DTS-ES Discrete 6.1), and DTS Neo:6 decoding with extreme accuracy.
96kHz/24-BIT DIGITAL-TO-ANALOG CONVERTER SYSTEM
The RX-V640's vitally important digital-to-analog converters use an extremely high performance 96kHz/24-bit operation type. They perform accurate sound field reproduction for high quality multi-channel sources, and for two-channel stereo, provide outstanding separation and precise musical delineation.
DISCRETE POWER TRANSISTORS
Discrete power transistors rather than IC chips are used in the amplifier section to provide the cleanest sound possible. The amp delivers 85 watts each to six channels.
24 DIFFERENT SOUND PROGRAMS YIELDING 44 VARIATIONS
Yamaha's exclusive Tri-Field Cinema DSP imaging for video sound and Digital Sound Field Processing for music delivers the most realistic and dramatic sound possible. The RX-V640 features 24 different sound programs that provide a total of 44 variations, so every movie and every piece of music will sound right in your home theater.
EXTENDED I/R CODES
The unit responds to extended I/R codes for custom installation applications.
PRESET REMOTE CONTROL UNIT
The RX-V640's remote control has built in preset codes for most other manufacturers' equipment, so you can use it as a single remote for the entire system.
DIGITALLY REGULATED ANALOG 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 easier and more accurate, and the result is the Digitally Regulated 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 with extreme accuracy.
DOLBY SURROUND PRO LOGIC II
This new Dolby format provides 5.1-channel surround from any stereo source. A Movie Mode and Music Mode are provided for optimum listening.
ALL-CHANNEL STEREO DSP
Great for casual listening and parties, Yamaha's 6-channel stereo DSP puts music through all speakers in the system and maintains stereo imaging.
QUAD-FIELD AND FRI-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.
Building on technology incorporated into its world famous "silent" musical instruments, Yamaha has added HRTF and "Virtual" technology to create a realistic surround movie effect using standard, two-channel headphones.
EXTENSIVE INPUTS AND OUTPUTS
In addition to the wide range of inputs and outputs provided on previous Yamaha receivers, the RX-V640 also includes a Video Conversion circuit (S-Video to Composite, Composite to S-Video).
CUSTOM INSTALLATION COMPATIBILITY
As befits a high performance home theater receiver, the RX-V640 is designed to be suitable for use in custom installations. It has a Zone 2 Selector so the audio signal can be output in a second room.
FIVE DIGITAL INPUTS, ONE DIGITAL OUTPUT
With five fully assignable digital inputs (4 optical and 1 coaxial), the RX-V640 can accommodate digital sources such as DVD, CD, MD/CDR, D-TV/CBL and a video game console. One optical digital output assures the finest possible signal leaving the receiver for your other component.
S-VIDEO AND COMPONENT VIDEO INPUTS AND OUTPUTS
The RX-V640 has five S-video inputs and two S-video outputs. The receiver incorporates two component video inputs.
FRONT PANEL A/V INPUTS WITH OPTICAL INPUT
For simple temporary connection, the receiver is equipped with a set of front panel A/V inputs, including a digital input and S-Video Terminals.
SPEAKER A/B SWITCHING
For convenience and versatility, the receiver can switch back and forth between two sets of speakers at the touch of a button.
PRE-OUTS FOR ALL CHANNELS INCLUDING SUBWOOFER
All channels and the subwoofer have pre-out connections. This allows you to add outboard amplification and direct subwoofer connection.
LOW IMPEDANCE DRIVE CAPABILITY AND IMPEDANCE SWITCHING
Yamaha's famed low impedance drive circuitry is included in this receiver so that it can handle virtually all loads and a wide variety of speakers. For further speaker matching, the amplifier can set for either 4-or 8-ohm speakers.
LINEAR DAMPING FACTOR CIRCUIT
The advantage of full range, 20 to 20,000 Hz, damping is that it improves the definition and resolution of the sound output throughout the audible frequency range.
Permits a delayed receiver turn off. You can set it for up to two hours in 30 minute increments.
40-STATION DIRECT ACCESS PRESET TUNING
Up to 40 preset AM and FM stations can be grouped in five groups eight stations. These groupings make it easy for family members to easily access their favorite stations or to have musical genres, such as all the jazz stations, grouped together.
BINDING POST SPEAKER TERMINALS
Yamaha's heavy-duty binding post speaker terminals accept banana plugs, spade connectors, and a variety of speaker wire, including heavy gauge cable.
