The dCS Vivaldi Master Clock is the temporal heart of the flagship Vivaldi digital playback system, serving as an indispensable component for achieving ultimate audio fidelity. Engineered to generate ultra-high-precision, low-jitter Word Clock signals, it rigorously synchronizes all digital components—typically the Vivaldi DAC, Upsampler, and Transport—ensuring perfect timing alignment. This eliminates timing errors (jitter) that can compromise sound quality, leading to unparalleled clarity, focus, and naturalness in musical reproduction.

The Master Clock incorporates two independent, temperature-controlled crystal oscillators (OCXO), meticulously tuned for 44.1 kHz and 48 kHz related sample rates, providing astonishing accuracy and stability. With eight individually buffered BNC outputs, it can simultaneously clock numerous devices. For those seeking absolute precision, it offers inputs to lock to an external reference, such as a Rubidium atomic clock. Housed in an aerospace-grade machined aluminum chassis designed to eliminate vibration and interference, the Vivaldi Master Clock represents the pinnacle of digital audio synchronization, unlocking the full potential of your high-end digital system.

- Utilises the latest generation dCS Digital Processing Platform for state-of-the-art measured performance and unrivalled musical experience.
- Dual crystal oscillators with microcontroller-enhanced temperature correction.
- New dual frequency output and auto-clocking mode used in the Vivaldi range improves ease of use and minimises jitter, particularly with computer audio sources.
- Improved power supplies give lower running temperature and improved tolerance to AC supply variations.
- Multi-stage regulation ensures sensitive clock and PLL circuitry is unaffected by digital interference.
- Aerospace-grade machined aluminium chassis fitted with tuned acoustic damping panels reduces magnetic effects and vibration.
