New circuit technology

Since the advent of digital audio, signal-to-noise ratios have improved dramatically. However, the S/N ratio reflects static noise only, and takes no account of another type of noise that occurs as the byproduct of sound reproduction—dynamic noise. To reduce this type of noise, Onkyo has developed New circuit technology for use in our hi-fi components. Despite being beyond the normal range of human hearing, frequencies above

100 kHz are susceptible to clock pulse and other forms of distortion from digital devices. Such distortion in the super-high-frequency range can generate “beat interference”, which in turn affects the character or atmosphere of the original sound. By improving linearity and reducing distortion in the super-high-frequency range, Onkyo’s new New circuit technology effectively reduces perceptible noise. New circuit technology is incorporated into the buffer circuitry of the C-7000R CD player.

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.

New 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.
