dCS Vivaldi Master Clock

In a digital audio system, accuracy in both level and timing is crucial, but jitter—present in all digital systems—can introduce timing errors, leading to inaccurate reconstruction of the analog signal. While the DAC in a dCS system can function as the master clock, listening tests have shown that a dedicated, high-quality master clock is indispensable for optimal performance. dCS pioneered the use of external clocks in digital audio, and their latest multi-stage Phase-Locked-Loop (PLL) system has set world-class standards for jitter control and timing accuracy.

Each dCS Master Clock undergoes rigorous in-house testing, with crystal oscillators pre-aged, selected for long-term stability, and calibrated over a wide temperature range to ensure consistent, optimal performance. The Vivaldi Master Clock utilizes a sophisticated microcontroller system to maintain stable performance as temperatures fluctuate, providing more stability than oven-controlled crystal oscillators or even atomic clocks.

dCS master clocks generate industry-standard Word Clock over 75-ohm coaxial cables, ensuring compatibility with other equipment designed to accept Word Clock. For those seeking even higher accuracy, the Vivaldi Master Clock can be slaved to an external reference, such as an atomic clock or GPS reference, with their advanced PLL technology reducing jitter from the reference source.

The dCS ‘soft’ approach to programmable logic allows users to easily update the Vivaldi Master Clock software, adding new features, enhancing performance, or adapting to changes in digital formats.

When used as part of the Vivaldi digital audio playback system, the Vivaldi Master Clock elevates the sound quality to an entirely new level. The addition of the clock sharpens image focus, increases the music's sense of authority and power, and significantly improves resolution and detail, enhancing the entire listening experience.
