dCS Vivaldi Master Clock


Based on our pioneering developments in studio and home audio, our Grade 1 master clock generates a precise reference signal that keeps your Vivaldi system running perfectly in sync, ensuring a natural, lifelike and three-dimensional performance


  • 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
