For music lovers who enjoy the tangible experience of playing a physical format, the CD retains its enduring appeal. The pleasure comes not just from browsing a collection of discs and reading the liner notes. It also comes from enjoying your music in superior fidelity. By combining high-quality components and decades of Onkyo audio know-how, the C-7030 CD player delivers a superb playback experience. The key lies in keeping the audio signal clean and free from interference, all the way to the output stage. To achieve this, we employ a new high-precision clock to dramatically reduce timing errors, along with our original VLSC™ to reduce pulse noise. Driving the system is a massive, custom-built transformer that provides a clean and stable power supply. Given how affordable the C-7030 is, build quality is exceptional. A 1.6 mm-thick flat chassis base helps reduce unwanted vibrations, while the sleek aluminum front panel provides an elegant finish.
- VLSC (Vector Linear Shaping Circuitry) virtually removes digital pulse noise for a smooth analog signal.
- CD Audio & MP3 playback
- RI (Remote Interactive) Capability
- Precision Clock
- Wolfson® 192 kHz/24-Bit DAC
With this common digital audio format, audio data is sampled at a rate of 44.1 KHz and 16 bits of resolution.
MP3 is a popular digital audio encoding and lossy compression format designed to greatly reduce the amount of data required to represent audio, yet still sound like a faithful reproduction of the original uncompressed source.
WMA (Windows Media Audio)
A proprietary compressed audio file format developed by Microsoft. Copied to CD-R/CD-RW, they can be played through most audio systems.
RI (Remote Interactive) Capability
Onkyo’s RI system lets you operate multiple RI-compatible components through a single remote control. RI capability also gives you further functionality with Onkyo’s Remote Interactive Dock for the iPod, including System On/System Off, Auto Power On, Auto Selector (Direct Change) and Timer functions.
In conventional digital-to-analog conversion methods, it’s impossible to completely remove noise. This noise taints the analog signal and ultimately degrades the sound emitted from your speakers. With Onkyo’s VLSC, though, data is continuously sampled between two discrete points—via a signal comparison generator—and the difference is joined with analog vectors in real time to produce a smooth output waveform. The VLSC digital-to-analog conversion method results in an accurate, virtually pulse noise-free audio signal that faithfully reproduces the acoustic detail and subtle nuances of all your audio sources, and breathes life into digital media.
Conventional D/A conversion methods reduce digital pulse noise at the conversion stage but can't remove it completely. VLSC employs a unique D/A conversion circuit to overcome this problem. Data is converted between sampling points and these points are joined with analog vectors in real time to produce a smooth output wave form. The result—a virtually noiseless, smooth, analog signal based on the digital source that brings out even the most subtle of nuances in music sources (including DVD-Audio and Super Audio CD), DVD Video sources (including high-definition), broadcasts, digital music files such as MP3s, and gaming content.
The C-7030 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-7030 uses a state-of-the-art crystal oscillator that achieves a frequency deviation of ±10 ppm—much lower than with a conventional oscillator.
A high-quality Wolfson digital-to-analog converter works to optimize audio performance on the C-7030. This DAC performs advanced 24-bit signal processing and supports sampling rates of up to 192 kHz, while displaying high resistance to clock jitter. With this DAC on board, the C-7030 delivers a pristine conversion of digital signals into analog audio output.
