About

Scarlatti DAC uses state-of-the-art dCS technology including the dCS Ring DAC™ Digital Processing Platform and Clocking System so that, as the hub of a digital audio system, an array of features guarantees amazing performance from any digital source.

The unique design of the legendary dCS Ring DAC™ combines exceptional linearity with very high speed operation enabling it to deliver true 24-bit performance even at low signal levels. The powerful digital processing platform of Scarlatti DAC is based around Field Programmable Gate Array (FPGA) chips, Digital Signal Processing (DSP) chips and a microcontroller system. All of these use code developed and maintained in the UK by dCS.

The optimised DSP filters available to Scarlatti DAC ensure you can extract every last nuance of musical detail by tuning the system to suit your personal preference.

Scarlatti DAC features standard AES3, S/PDIF and SDIF-2 inputs in addition to the recently enhanced Dual AES or IEEE 1394 interface for DSD. The digital volume control allows direct connection to a power amplifier; there is no need for a preamplifier. Maximum output can be either two or six volts to suit different amplifier and loudspeaker combinations.

The unit can be used in Master mode to provide a clock for the source or be locked to an external Word Clock signal generated by a dCS Master Clock – this produces a substantial performance improvement.

dCS pioneered the use of external clocks in digital audio systems and the multi-stage Phase-Locked-Loop (PLL) system used in Scarlatti DAC sets reference standards for accuracy and control of troublesome jitter from the incoming audio stream.

To realise the very best performance, Scarlatti DAC should be used with the matching Scarlatti Upsampler, Scarlatti CD/SACD Transport and Scarlatti Master Clock. Alternatively Scarlatti DAC can be used with any industry-standard CD transport, digital streamer or music server.

All Scarlatti products benefit from our ‘soft’ approach to programmable logic that allows new software to be loaded from a dCS update disc to add new features and adapt to changes in digital formats.

Key Features

  • Flexible output configuration can be optimised in systems with or without preamplifiers.
  • All dCS products use a sophisticated multi-mode Phase-Locked-Loop (PLL), which significantly reduces clock jitter.
  • Improved power supplies give lower running temperature and superior tolerance to AC supply variations.
  • Aerospace-grade aluminium chassis and laminated acoustic damping panels reduce magnetic effects and vibration.
  • Low-power LC display makes the user interface easier to read, keeps power requirements down and minimises electrical noise.
  • Separate power circuits for the digital and analogue sections further enhance the purity of the power supply.
  • ‘Soft’ approach to programmable logic allows new software to be loaded from a dCS update CD to add new features and adapt to changes in digital formats.

  • analogue outputs

    Output Levels: 2V rms or 6V rms on all outputs for a full-scale input, set in the menu.
    Balanced Outputs: 1 stereo pair on 2x 3-pin male XLR connectors (pin 2 = hot, pin 3 = cold). These outputs are electronically balanced and floating, the signal balance ratio at 1kHz is better than 40dB, Output impedance is 3Ω, maximum load is 600Ω (a 10kΩ load is recommended).
    Unbalanced Outputs: 1 stereo pair on 2x RCA Phono connectors. Output impedance is 52Ω, maximum load is 600Ω (a 10kΩ load is recommended).

  • digital inputs

    IEEE 1394 interface on 2x 6-way connectors. The interface accepts dCS-encrypted DSD (1 bit data at 2.822MS/s).
    2x AES/EBU on 3-pin female XLR connectors. Each will accept up to 24 bit PCM at 32, 44.1, 48, 88.2, 96, 176.4 & 192kS/s and DoP DSD over PCM) OR as a Dual AES pair, 24 bit PCM data at 88.2, 96, 176.4, 192, 352.8 & 384 kS/s or DoP or dCS-encrypted DSD.
    3x SPDIF on 2x RCA Phono and 1x BNC connectors. Each will accept up to 24 bit PCM at 32, 44.1, 48, 88.2, 96, 176.4 & 192kS/s AND DOP (DSD over PCM).
    1x SPDIF optical on a Toslink connector, will accept up to 24 bit PCM at 32, 44.1, 48, 88.2 & 96kS/s.
    1x SDIF-2 interface on 2x BNC connectors, will accept up to 24 bit PCM at 32, 44.1, 48, 88.2 & 96kS/s or SDIF-2 DSD (auto-selected). If the unit is not in Master mode, this interface requires a compatible Word Clock input, locked to the data rate.

  • worldclock inputs

    Word Clock input on 1x BNC connector. Accepts standard Word Clock at 32, 44.1, 48, 88.2, 96, 176.4 & 192kHz. The data rate can be the same as the clock rate or an exact multiple (0.5x, 1x, 2x, 4x) of the clock rate. Sensitive to TTL levels.
    Word Clock output on 1x BNC connector. In Master mode, a TTL-compatible 44.1kHz Word Clock is available.

  • residual noise
