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.

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).
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.
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.
