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.
