dCS  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):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，所有的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及Paganini和Puccini一樣採用dCS Ring DAC技術，將所有訊號可超取樣至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。

Analogue Outputs
|
Output 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 3 Ω , maximum load is 600 Ω (a
10k Ω load is recommended).
These outputs are electronically balanced and floating - the signal balance ratio at 1kHz is better than 40dB Output impedance is 3 Ω and maximum load is 600Ω (a 10kΩ load is recommended).
Unbalanced Outputs - 1 stereo pair of 2x RCA Phono
connectors. Output impedance is 52Ω maximum load
is 600 Ω (a 10kΩ load is recommended).

2x AES/EBU on 3-pin female XLR connectors. Each will accept up to 24bit PCM at 32, 44.1, 48, 88.2 &96kS/s.
OR as a Dual AES pair at 88.2, 96, 176.4 & 192kS/s.
2x SPDIF on 1x RCA Phono and 1x BNC connectors.
Each will accept PCM at 32, 44.1, 48, 88.2 or 96kS/s
up to 24 bits.

Word Clock I/O
|
INPUT - Word Clock Input on 1x BNC connector.
Accepts standard word clock at 32, 44.1, 48, 88.2 & 96kHz.
|
|
Residual Noise
|
Better than -100dB0 @ 20Hz - 20kHz unweighted.(6V Setting).
|
|
Spurious Responses
|
Better than - 100dB0 @ 20Hz - 20kHz.
|
| Filters |
2 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 Updates
|
Loaded from CD or Computer via USB.
|
|
Local Control
|
IR (RC5) or RS232. A dCS Premium remote control is available as an optional extra.
USB Mode Volume Control - Debussy volume can be controlled by either Vol +/- buttons or the volume control on the computer used as a source.
Media Player Transport Controls - Debussy implements a USB HID interface. This means that not only can the user change the Debussy volume via the attached computer, but Debussy can also perform functions such as Play/Pause”/"Media Next”/"Media Prev”/"Media FF/RW”.
