DIDRC (Dynamic Intermodulation Distortion Reduction Circuitry)

Since the advent of digital audio, the values of S/N (signal-to-noise) ratio have risen significantly. However, it is also recognized that in terms of perceived S/N, analog audio sources are not inferior to digital sources.

Generally, S/N measures the ratio when sound is and not produced, but takes no account of the noise generated during sound reproduction.

For a long time, Onkyo has focused and made extensive research on the S/N when sound is produced (dynamic S/N). Using a mechanism that captures the noise beyond audible range, it has been possible to determine that both dynamic S/N and perceived S/N aggravate during music reproduction.

Although frequencies above 20 kHz are beyond human hearing, it is well known that a beat can be perceived if different signals are overlapped at such frequencies.

During the analog audio era, no significant signals were entering beyond the audible range. However, the digital era has made recording beyond the audible range possible and the generated beat is now perceivable.

With Onkyo’s DIDRC technology, a new approach is introduced which prevents such beat from penetrating the audible range.

Separate Digital/Analog Circuitry and Transformers

To prevent unwanted interference, the C-7000R employs physically separate circuitry for digital and analog processing. In the same vein, the player also features separate transformers for digital and analog circuitry.

Thermally Regulated Super-Precision Clock

The C-7000R boasts an extremely precise clocking mechanism that controls and coordinates the timing of all digital signal processes—rather like how a conductor directs and coordinates the individual instruments of an orchestra. The C-7000R uses a state-of-the- art crystal oscillator that achieves a frequency deviation of ±1.5 ppm at room temperature- much lower than with a conventional oscillator. Even in surrounding temperatures of -30°C or +80°C the frequency remains stable, with only ±0.5 ppm of additional frequency deviation.

PLL (Phase Locked Loop) Ultra-Low Jitter Technology

Jitter is an unwanted side-effect of the digital- to-analog conversion process caused by fluctuations in the time domain of a digital signal. PLL ultra-low jitter technology reduces jitter by comparing the input and output phases of the digital signal and creating an accurate clock waveform. This enhances the precision of digital signal processing and noticeably improves perceived audio quality.

Side-mounted Circuit Board Construction

Rather than being directly connected to the chassis base, the circuit boards inside the C-7000R are cushioned by internal struts and affixed to the front, side, and rear panels. This method of construction prevents vibrations from the chassis from adversely affecting the circuit boards.
