Debussy U-DAC USB數位類比轉換器

DebussyUSB數位類比處理器將會是未來音響系統的趨勢。

Debussy結合了 dCS Ring DAC 技術和dCS專利証號(GB0817141.5),讓USB與電腦連接的非同步模式,因此,DebussyUSB數位類比處理器能使任何數位訊源完美呈現並無限延伸。

Debussy以鋁合金高度精密製作,打造華麗時尚的外型,所有按鍵也是高精密金屬打造,無論是CD還是電腦訊源,Debussy都能精準掌握每個細節,讓你聽見夢寐以求的聲音。與旗艦Scarlatti、Paganini和Puccini一樣採用dCS Ring DAC技術,將所有訊號超取樣至5 bits 在 2.822 或 3.07 MS/s。Debussy的數位輸入有AES3、Dual AES、SPDIF及USB 2.0,數位音量控制可與後級直接搭配使用而不需要前級,最大的輸出可以選擇2V或6V來配合不同的擴大機與喇叭。兩組濾波,分別為linear phase with pre-ringing or non-linear phase without pre-ringing。

與電腦連結時,Debussy 會啟動USB非同步模式,提供電腦非同步模式訊號來同步電腦,如此,時鐘便能更為精準且jitter也更低。AES和SPDIF數位輸入介面是所有數位類比處理器的工業標準,因此,可以和其他的器材搭配使用。Debussy也可以外接任何一台dCS的主時鐘系統,讓它的表現效率更好。在未來,無論用dCS的CD片,還是透過電腦,Debussy的軟體、韌體都可輕易更新升級。

Specification
TypeDigital-to-Analogue Converter.
ColourSilver or Black.
Dimensions445mm/17.6” x 392mm/15.5” x 65mm/2.6”. Allow extra depth for cable connectors.
Weight8.8kg/19.4lbs.
Converter TypedCS proprietary Ring DAC™ topology.
Analogue OutputsOutput Levels: 2V rms or 6V rms on all outputs, set by the Output Level switch on the rear panel.
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 InputsUSB interface on a B-type connector will accept up to 24 bit PCM at 44.1, 88.2, 96, 176.4 & 192 kS/s or DSD in DOP format. Operates in asynchronous mode.
2x AES/EBU on 3-pin female XLR connectors. Each will accept 24 bit PCM data at 32, 44.1, 48, 88.2, 96, 176.4 & 192 kS/s or DSD in DOP format OR as a Dual AES pair at 88.2, 96, 176.4 & 192kS/s or DSD in DoP format.
2x SPDIF on 1x RCA Phono and 1x BNC connectors. Each will accept 24 bit PCM data at 32, 44.1, 48, 88.2, 96, 176.4 & 192 kS/s or DSD in DOP format.
Wordclock I/OWord Clock input on 1x BNC connector. Accepts standard Word Clock at 32, 44.1, 88.2, 96, 176.4 & 192kS/s.
Residual NoiseLess than -110dB0 @ 20Hz-20kHz unweighted (6V Setting).
Spurious ResponsesBetter than -100dB0 @ 20Hz-20kHz.
Filters2 filters on Debussy give different trade-offs between the Nyquist image rejection and the phase response. Filter 1 is a classic sharp filter, with linear phase and pre-ringing. Filter 2 is an alternative filter, which has non-linear phase and no pre-ringing.
Software UpdatesLoaded from CD or PC via USB or PCM digital inputs.
Local ControlIR (RC5) or RS232. A dCS Premium remote control is supplied as standard.
Operating SystemsTested on Windows XP/Vista/7 and Mac OSX. Operates in ‘Audio Class’ mode. Class 1 mode (limited to 96kS/s) 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.
Power SupplyFactory set for 100, 115, 220 or 230V AC, 49-62Hz.
Power Consumption22 Watts typical/30 Watts maximum.
