DIDRC (Dynamic Intermodulation Distortion Reduction Circuitry)
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 DIDRC 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 DIDRC technology effectively reduces perceptible noise and delivers clearer-than-ever audio.
 
Precision Clock
The C-7070 boasts a 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-7070 uses a state-of-the-art crystal oscillator that achieves a frequency deviation of ±10 ppm—much lower than with a conventional oscillator.
 
Separate Wolfson® 192 kHz/24-Bit DACs for L/R Channels
High-quality Wolfson digital-to-analog converters work to optimize analog audio performance on the C-7070. The player incorporates two 24-bit WM8742 DACs. Although these DACs can process two-channel audio on a single chip, Onkyo employs separate chips for each stereo channel, to ensure the most accurate digital-to-analog conversion.
 
Silent Disc Mechanism with Die-Cast Tray
Affixed to four supports made of rigid machined brass, the C-7070’s CD drive provides excellent resistance to internal vibrations. Furthermore, the disc tray is precision-engineered from high-rigidity, die-cast aluminum. Thanks to these advanced design features, the disc mechanism offers smooth and silent operation.
 
Fully Flat Anti-Vibration Chassis
When it comes to parts and construction, it’s not in Onkyo’s DNA to cut any corners. The C-7070 is no exception. Build quality starts from the ground up with a highly rigid, 1.6 mm-thick, fully flat chassis that provides excellent protection against shelf-borne vibrations.
 
Floating Circuit Board Construction
Rather than being directly connected to the chassis, the main circuit board inside the C-7070 is now “floating” to protect it from sources of vibration. This method of construction prevents vibration from the chassis and CD drive mechanism from adversely affecting the circuit boards or creating signal interference. Which adds up to longer life and cleaner audio.
