The new dCS Rossini DAC makes superlative sounding music from a wide range of digital sources, simply integrating your digital music and setting the performance standard for digita l playback. This single-box digital music player features the legendary dCS Ring DACTM and signal processing platform plus a custom high performance UPnP music streamer. Rossini plays music through an array of industry-standard USB, AES and S/PDIF digital inputs, and can stream over Ethernet from a NAS drive or online music services such as TIDALTM, SpotifyTM and from Apple devices via AirplayTM . Designed for flexibility and ease of use without compromise, Rossini uses the very latest dCS Digital Processing Platform and Ring DACTM technology, originally developed for the flagship Vivaldi series. Its single FPGA brings improved signal processing and superior flexibility, effectively making it future-proof. Rossini DAC has a powerful new user interface, plus a custom control app that lets listeners manage their music playback from any source in an elegantly simple way – accessing iRadio channels, digital and UPnP sources from one control point. The Rossini app also features an intuitive install and configuration wizard for ease of set-up. Featuring DXD upsampling as standard, the multi-stage oversampling design offers optional DSD upsampling plus an extensive selection of DSP filters to suit individual taste and music choice. The network streaming functionality within Rossini DAC is unparalleled in its processing power and jitter performance, and currently runs at up to 24-bit, 384kS/s and DSD128, supporting all major lossless codecs, plus DSD in DoP format and native DSD. Rossini supports the simple yet highly effective dCS ‘auto clocking’ architecture as used in Vivaldi, which minimises jitter and improves sound quality significantly. Designed and made in Great Britain to the highest standards, Rossini’s elegant chassis uses aerospace-grade machined aluminium with internal acoustic damping panels to reduce sound-degrading mechanical vibration and magnetic effects. Multi-stage power regulation is employed, with twin mains transformers to isolate the analogue, digital and clock circuitry. As with all dCS products, Rossini’s firmware can be easily updated via CD, USB or the new automated download and update facility. This lets dCS add new features and improve the performance of Rossini over its lifetime. When listening to digital music through a Rossini system, 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.

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.
