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.Īffixed to four supports made of rigid machined brass, the C-7070’s CD drive provides excellent resistance to internal vibrations.
The player incorporates two 24-bit WM8742 DACs. High-quality Wolfson digital-to-analog converters work to optimize analog audio performance on the C-7070. Separate Wolfson® 192 kHz/24-Bit DACs for L/R Channels The C-7070 uses a state-of-the-art crystal oscillator that achieves a frequency deviation of ☑0 ppm much lower than with a conventional oscillator. 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. 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. Such distortion in the super-highfrequency range can generate “beat interference”, which in turn affects the character or atmosphere of the original sound. 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. To reduce this type of noise, Onkyo has developed DIDRC technology for use in our hi-fi components. 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. Since the advent of digital audio, signal-to-noise ratios have improved dramatically. All this adds up to a player that, like your CD collection, will be around for a long time to come.ĭIDRC (Dynamic Intermodulation Distortion Reduction Circuitry) The three-stage dimmer function, gold-plated audio terminals, and headphone amplifier differential circuitry offer further evidence of Onkyo’s attention to detail. It also connects to your iPod/iPhone via the USB port, and plays music straight off a USB thumb drive. Naturally, the C-7070 plays audio discs or CD-R/ CD-RWs and your favorite MP3/WMA compilation CDs. These improvements all but eliminate noise from the source, meaning your music will sound clearer than ever. 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). The unit is strengthened with vibration-damping 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. For 2011, the C-7070 is an extremely versatile and sophisticated piece of audio equipment. Onkyo C-7070 Compact Disc Player, it’s difficult to imagine how you could improve the humble CD player, but Onkyo’s engineering team had plenty of inspiration. Additionally, to ensure most accurate audio conversion each audio channel is incorporated with separate Wolfson 192 kHz/24-bit DAC chip individually. Onkyo C-7070 Compact Disc Player is an extremely versatile and sophisticated HiFi component that significantly reduce noise from vibration and CD tray mechanism to give clear music output.
