RX-D702

There are several high-bit/upsampling processing systems on the market that claim to offer the same benefits as the CC Converter. They are all designed to create and add frequencies (harmonics) over 20kHz deriving from an input signal.

But we do not believe the mechanical addition of harmonics can ensure the faithful recreation of “musicality.” The sound generated by an instrument contains harmonic components. And it is the harmonic components that determine the tone of an instrument. The harmonic components of one violin are different than those of another. One player’s phrasing produces different harmonic components from one by others. Some instruments feature rich resonance, while others produce hardly any.

Therefore, applying the same process for adding harmonic components is not proper in view of “musicality.” Reviewers of European audio magazines are highly critical of this approach. Moreover, the existing high-bit/upsampling processing systems use 2x sampling frequencies -- 88.2kHz for CDs to achieve a 44.1kHz frequency range, or 96kHz for DVD Video to achieve a 48kHz frequency range.

CC Converter

JVC’s CC Converter does not simply create and add harmonic components. It computes the data that was lost during the D/A conversion by taking advantage of JVC’s exclusive algorithms. This means the CC Converter has the processing power to recreate the original signal that should have been recorded -- based on the digital signals for the audible range recorded on a CD.

Accurate D/A conversion and reproduction of the recreated data requires a process to expand the frequency range of the analog signals. The frequency-range expansion of the analog signals to beyond 20kHz results in improved music data for the audible range. The CC Converter expands CD’s frequency range fourfold to 88.2kHz using 176.4kHz (44.1kHz x 4) sampling frequency. With DVD-Video, the frequency range is expanded to 96kHz, while the sampling frequency is 192kHz (48kHz x 4).
