The Onkyo C-7000R optimises the audio experience of listening to CDs by using clever playback and manufacture technology to reduce noise and minimise auxillary vibrations.
Available in both Silver and Black, the unit is a smart looking CD player that'll accept all manner of CDs, including CDR, WMA and MP3 encoded discs.
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 new DIDRC technology effectively reduces perceptible noise and delivers clearer-than-ever audio.
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
The C-7000R incorporates a massive toroidal transformer for the analog circuitry that reduces magnetic flux leakage, improves efficiency, and keeps the power supply stable. For the digital circuitry, meanwhile, it employs a high-quality EI transformer. Wide-spaced, gold-plated, machined solid brass terminals ensure a clean connection and help prevent interference between thick, high-quality cables. Meanwhile, Amphenol AES/EBU digital outputs provide resistance to signal degradation and noise.
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.
Separate Panel Construction
The C-7000R features separate aluminum panels for the top, sides, and front to reduce unwanted vibrations caused by internal resonance. Compared to a one-piece chassis design, this construction method offers greater rigidity and improved noise reduction.
Silent Disc Mechanism with Die-Cast Tray
Affixed to four supports made of rigid machined brass, the C-7000R’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.
Separate TI Burr-Brown DACs for L/R Channels
High-quality TI Burr-Brown DACs work to optimize analog audio performance on the C-7000R. The player incorporates two of TI Burr-Brown’s flagship 24-bit PCM1792 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.
