- Four Word Clock outputs further reduce jitter and improve sonic performance.
- Asynchronous USB input allows direct connection of a computer audio source and supports high resolution files up to 192kS/s PCM, and DSD in DoP format.
- Isochronous and asynchronous USB mode prevents the source injecting jitter into DAC.
- High-grade aluminium chassis and laminated acoustic damping panels reduce magnetic effects and vibration.
|Colour||Silver or Black.|
|Dimensions (WxDxH)||400mm/15.8” x 410mm/16.2” x 58mm/2.3”. Allow extra depth for cable connectors.|
|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.|
|Worldclock Inputs||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.|
|Startup 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.|
