96kHz/24-Bit DACs for All Channels
The RX-V640’s vitally important digital-to-
analog converters use an extremely
96kHz/24-bit high performance. They
perform accurate sound field
reproduction for high quality multi-channel
sources, and for two-channel stereo,
provide outstanding separation and
precise musical delineation. They deliver
superior low level linearity with excellent
full-scale performance under varying
operation conditions.
4-Layer DSP Processing Board
All of the DSP IC chips and related
circuitry are located together on a 4-layer
board. This is the first time a 4-layer
board has been used, and it provides a
number of advantages. The dimensions

Technology) is the
name Yamaha has given to a design
philosophy whose goal is to maximize
digital quality while minimizing analog
circuitry. The culmination of the best
digital engineering and design possible
today, it brings together several key
elements to create the best-sounding,
easiest-to-use A/V components available

The decoding circuitry performs Dolby
Pro Logic II, Dolby Digital, Dolby Digital
EX, DTS Digital Surround, DTS-ES (DTS-
ES Matrix 6.1 and DTS-ES Discrete 6.1),
and DTS Neo:6 decoding with extreme
accuracy, as well as all digital sound
field processing. It also outperforms
other systems in the precise
synchronization of images and sound. Its
low 3V power consumption minimizes
digital noise.
