About

The new dCS Rossini range makes superlative sounding music from a wide range of digital sources, simply integrating your digital music and setting the performance standard for digital playback.

Rossini Master Clock is a simple to use Grade 1 master clock, based on our pioneering developments in studio and home audio. Featuring three separate clock outputs capable of outputting different frequencies, Rossini Master Clock allows Rossini DAC or Player users to benefit from the auto clocking mode in Rossini and optimise audio from various digital sources in a simple, fuss free way.

In a digital audio system, samples must be accurately transferred at the correct time. Instability in the sample timing is called jitter – this exists in all digital systems. Severe jitter results in timing errors in the delivery of data to the DAC, causing the analogue signal to be reconstructed inaccurately.

In a dCS system, the DAC can act as the system master clock, but listening tests have shown that there is no substitute for a high quality, dedicated master clock.

dCS pioneered the use of external clocks in digital audio systems. Our clocking technology has been continually refined so that our latest multi-stage Phase-Locked- Loop (PLL) system sets world-beating standards for accuracy and control of troublesome jitter from the incoming audio stream.

All dCS Master Clocks are subjected to rigorous in-house testing. The crystal oscillators are pre-aged, selected for long term stability and then individually calibrated over a wide temperature range to ensure consistent optimal performance. Rossini Master Clock uses a sophisticated microcontroller system to ensure smooth frequency correction as the temperature changes, and this approach gives a more stable result than either oven-controlled crystal oscillators or even atomic clocks.

All dCS Master Clocks are designed to generate industry-standard Word Clock over a 75 ohm coaxial cable. Other manufacturers’ equipment that has been designed to accept standard Word Clock can be used with our clocks.

When listening to digital music through a Rossini system, Rossini Master Clock improves on an already spectacular sound and takes it into an entirely new domain. Listeners are immediately struck by its natural musicality and faithfulness to the original recording. It delivers a powerful and visceral sound yet is highly transparent too, making for an immersive and realistic listening experience.

Key Features

  • 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.

    HiFi Critic – dCS Rossini Player and Clock

    Review by Chris Binns

    HiFi Critic April – June 2016

    ‘A performance that allows the listener to get deeply involved with the music, and more directly connects to the heart and soul with little or no effort. The Rossini excels in creating a sense of believable musical realism, and that is far closer to where I would like digital audio reproduction to be.’

    Raising the Bar – dCS Rossini

    Review by Jeff Dorgay

    Tone Audio #77

    The sutle growl in Plastikman’s “Mind Encode”
    rolls out into my listening room in such a sinister,
    encompassing way, it’s almost frightening. It
    instantly reminds me of the aural magic that its
    much more expensive sibling, the four box Vivaldi,
    which until now was the only digital playback
    system capable of being this visceral.

    Vivaldi y Rossini: de nuevo la magia de dCS

    Pocas marcas han sabido hilar tan fino a la hora de dotar de “alma” al audio digital doméstico
    como la británica dCS. ¿El motivo? Un dominio de la tecnología “pro” más avanzada cuya expresión
    más reciente la encontramos en el modelo Rossini, presentado en sociedad en el icónico loft de la
    barcelonesa Werner.
