    DCS Puccini CD/SACD Player
    Tính năng chính của DCS Puccini CD/SACD Player

    + Puccini upsamples Red Book CDs to DSD and plays SACDs in their native format.

    + Puccini uses the latest version of our patented dCS Ring DAC, which has several detail improvements over earlier versions.

    + The dCS Ring DAC is a discrete balanced design which does not use any off-the-shelf DAC chips commonly found in other manufacturers’ products

    + Our proprietary 5 bit oversampling topology produces exceptional linearity across the dynamic range.

    + All dCS products use a sophisticated multi-mode phase locked loop (PLL), which significantly reduces clock jitter

    + Faster, 100% accurate Digital Signal Processors (within the bounds of their resolution) give improved filters, revealing yet more fine detail.

    + 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

    + 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.

    + High grade aluminium chassis and laminated acoustic damping panels reduce magnetic effects and vibration.

    + Puccini features a low-power LCD display that makes the user interface easier to read, keeps the power requirements down and minimises electrical noise

    DCS Puccini U-clock
    Tính năng chính của DCS Puccini U-clock

    DCS Puccini U-Clock also features a USB-to-S/PDIF converter, which lets owners play high resolution audio from a computer through the legendary dCS Ring DAC™ inside the Puccini.

    dCS equipment is designed to generate and accept industry-standard Word Clock on 75 ohm coaxial cable. dCS Clocks will drive other manufacturers’ equipment designed to accept standard Word Clock. Non-standard clock formats must be assumed to be proprietary to that manufacturer.

    USB has numerous modes for synchronising the audio between a host computer and an audio device such as a DAC. ‘Adaptive’ is the most popular of these, and involves the audio device synchronising itself to the USB ‘frame’ provided by the computer. However, this tends to give poor jitter performance so Puccini U-Clock operates in asynchronous mode, where the audio device synchronises the audio by providing a feedback pipe to the computer. The computer is effectively locked to the audio device, which then benefits from a much more accurate clock for dramatically lower jitter. USB is isochronous, which means that the host (PC) and client (Puccini U-Clock) both know how much bandwidth is available at the outset, so the host can guarantee that bandwidth will be available all the time.

    Music files may be stored on an external Hard Disc Drive (HDD) or Network Attached Storage (NAS) in a different room, networked to a small, silent Mac or PC connected by USB cable to the Puccini U-Clock. When the user selects the audio for playback, the computer streams music from the HDD or NAS device, then outputs the data via USB.
    Thông số kỹ thuật:
    Type System Clock.
    Clock Frequencies 44.1kHz or 48kHz.
    Colour Silver or Black.
    Dimensions (WxDxH) 400mm/15.8” x 410mm/16.2” x 58mm/2.3”. Allow extra depth for cable connectors.
    Weight 7.6kg/16.7lbs.
    Clock Accuracy Better than +/-1ppm when shipped over an ambient temperature range of 10°C to 30°C (guaranteed for 12 months from shipping). Typically +/-0.1ppm when shipped and stabilised.
    Word Clock I/O 4 independently buffered outputs on 75Ω BNC connectors, all carry the same clock frequency. With the USB interface active at 32, 48, 96 or 192kS/s, the Word Clock outputs are set to 48kHz. With the USB interface active at 44.1, 88.2 or 176.4kS/s, the Word Clock outputs are set to 44.1kHz. USB Auto Frequency mode can be disabled from the front panel.
    Digital Inputs USB 2.0 interface on type B connector accepts uncompressed audio data at 32, 44.1, 48, 88.2, 96, 176.4 & 192kS/s plus DOP.
    Digital Outputs Puccini U-Clock will present data received via the USB interface, unprocessed, in SPDIF format via 2 x RCA Phono connectors. DSD in DOP format will be passed through unchanged.
    Operating Systems Tested on Windows XP/Vista/7 and Mac OSX. Operates in ‘Audio Class’ mode. Class 1 mode (limited to 96kS/s) is available and does not require special drivers to be installed. Class 2 mode requires the dCS drivers (supplied) to be installed on Windows PCs. Not required for OSX 10.6.3 or later.
    File Formats Packetised PCM at 32, 44.1, 48, 88.2, 176.4 & 192kS/s.
    Start Up Time Typically 1 minute to rated accuracy.
    Power Supply Factory set for 100, 115, 220 or 230V AC, 49-62Hz.
    Power Consumption 3 Watts typical/6 Watts maximum.
