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.

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.
