Scarlatti Master Clock
Our design philosophy in building Scarlatti was to use our 21 years of experience to deliver the best digital playback components in the business without compromise. For people who are serious about their music, the natural realism delivered by Scarlatti is like no other system on the planet.
Clocking is very important in an audio system because any timing errors that occur in the DAC will be converted directly into errors in the analogue output. Our DACs can act as the system master clock, but listening tests have shown that there is no substitute for a high-quality, dedicated master clock.
Scarlatti Master Clock is based on our professional master clocks and the highly successful Verona clock. All of our Master Clocks are subjected to rigorous in-house testing, the crystal oscillators being pre-aged and selected for long term stability.
dCS equipment is designed to generate and accept industry standard Word Clock on 75 ohm co-axial cable. Other manufacturers' equipment designed to accept standard Word Clock can be used with our clocks. Non-standard clock formats must be assumed to be proprietary to that manufacturer.
All of the Scarlatti products benefit from our ‘soft' approach to programmable logic which allows new software to be loaded from a dCS update CD to add new features and adapt to changes in digital formats.
Our clocks can lock to an external source such as a rubidium frequency standard or a GPS receiver, if even better accuracy is required but in our experience stability is much more important in a consumer system than extreme accuracy.

Product DatasheetKey Features
- Scarlatti Master Clock is a grade 1 master clock, featuring 8 word clock outputs.
- All dCS products use a sophisticated multi-mode phase locked loop (PLL), which significantly reduces clock jitter.
- Higher capacity FPGAs (Field Programmable Gate Arrays) give more logic capacity and increase the scope for additional features and enhancements.
- Improved power supplies give lower running temperature and increased tolerance to AC supply variations.
- 16-bit micro-controller for a generally improved control system.
- Aero grade aluminium chassis and laminated acoustic damping panels, reduce magnetic effects and vibration.
- The Scarlatti range features a low-power LCD display that makes the user interface easier to read, keeps the power requirements down and minimises electrical noise.
- Our ‘soft' approach to programmable logic allows dCS products to adapt to changes in digital formats and add new features by loading new software from a CD.
