Onkyo C-7070 CD Player

Onkyo C-7070 CD Player

It’s difficult to imagine how you could improve the humble CD player, but Onkyo’s engineering team had plenty of inspiration. For 2011, the C-7070 is an extremely versatile and sophisticated piece of audio equipment. The unit is strengthened with vibration-damping machined-brass legs, a 1.6 mm thick flat-base chassis, an aluminum CD tray with silent mechanism, a full-floating circuit board, and a handsome aluminum front panel. In addition, the electrical system benefits from a precision clock, a pair of Wolfson® 192 kHz/24-bit DACs-one for each channel-and Onkyo’s DIDRC (Dynamic Intermodulation Distortion Reduction Circuitry). These improvements all but eliminate noise from the source, meaning your music will sound clearer than ever. Naturally, the C-7070 plays audio discs or CD-R/CD-RWs and your favorite MP3/WMA compilation CDs. It also connects to your iPod/iPhone via the USB port, and plays music straight off a USB thumb drive. The three-stage dimmer function, gold-plated audio terminals, and headphone amplifier differential circuitry offer further evidence of Onkyo’s attention to detail. All this adds up to a player that, like your CD collection, will be around for a long time to come.

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 precisionengineered

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.
