The dCS Rossini Master Clock is an essential companion to the dCS Rossini DAC or Rossini Player, unlocking a higher echelon of sonic performance by providing a flawlessly precise timing reference. This dedicated Word Clock generator incorporates two independent, temperature-controlled crystal oscillators (OCXOs), one for 44.1 kHz related sample rates and another for 48 kHz related rates. These ultra-stable clocks virtually eliminate timing errors (jitter) between digital components, a crucial factor in achieving pristine digital-to-analog conversion.

By supplying its connected Rossini component with a single, highly accurate master clock signal via two independently buffered BNC outputs, the Rossini Master Clock ensures absolute synchronization. This dramatically improves clarity, tightens bass, sharpens transients, and expands the soundstage, revealing subtle nuances and dynamic contrasts that would otherwise be obscured. Housed in a precision-machined aerospace-grade aluminum chassis with an isolated power supply to further reduce interference, the dCS Rossini Master Clock is a testament to dCS’s expertise in digital timing, delivering a profound and immediately audible enhancement to the entire Rossini listening experience.

- Designed for maximum flexibility as output configuration can be optimised in systems with a wide variety of digital audio sources
- Dual crystal oscillators with microcontroller-enhanced temperature correction
- New dual frequency output and auto-clocking mode used in the Vivaldi and Rossini range improves ease of use and minimises jitter, particularly with computer audio sources
- 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
