Vivaldi DAC 數位類比轉換器

dCS Vivaldi新旗艦,重新定義何謂頂尖數位播放系統,其設計完全呈現”絕不妥協”的顛峰之作,無人能敵的家庭式音樂系統,更締造了未來數位音響最新標竿。

Vivaldi DAC 使用最創新的技術及最新一代的dCS Ring DAC 數位運作平台及時鐘系統,身為數位音響系統的核心,dCS Vivaldi DAC 保證帶給您最優異的音質表現。

獨家專利dCS Ring DAC技術包含線性與超高速操作方式,即使在低訊號規格中亦能傳輸24 bit音質表現。而最新一代的dCS Ring DAC技術添加了數個重要的科技,可提供更具動態及真實性的音樂表現,以及更低阻抗和優化的頻道分離技術。

Vivaldi DAC 的數位操作平台是由Field Programmable Gate Array(FPGA)晶片,數位訊號操作(DSP)晶片以及微控制系統組合而成。它們皆是由英國dCS編碼開發而成。Vivaldi DAC最先進的數位音響可提供比上一代高2倍的邏輯運算能力,強調無與倫比的音質和精準的表現。

dCS 是音響外部時鐘的先驅,Vivaldi DAC中的新一代多位階相位鎖定迴路系統Phase-Locked-Loop(PLL) 除了相當的精準,還能有效控制從音響串流進入的阻抗。

Vivaldi DAC標準的AES3,Dual AES, SDIF-2及SPDIF輸入端子,此外,還有非同步USB 2.0介面。先進的數位音量控制能直接連接擴大機,因此對於主系統而言,不需要額外分離的前級擴大機。輸出端子可以設置2或是6伏特來搭配不同的擴大機及喇叭組合。

以完整的新介面為特色,可操作所有高解析的音樂格式提昇至DXD(24bit data at 352.8及384kS/s)以及DSD,完美的DSP過濾器可以讓Vivaldi DAC用戶,藉由調整音調選擇喜愛的音質細節表現方式。

dCS 簡易的可編程式邏輯可以讓用戶輕鬆升級Vivaldi DAC軟體,或是添增新的功能,將表現提昇甚至是更改數位格式。

Analogue OutputsOutput Levels: 0.2V, 0.6V, 2V 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-100kΩ load is recommended).
Unbalanced Outputs: 1 stereo pair on 2x RCA Phono connectors. Output impedance is 52Ω, maximum load is 600Ω (a 10kΩ-100kΩ load is recommended).
Digital InputsUSB 2.0 interface on a type B connector. Operates in asynchronous mode, will accept PCM data up to 24 bits at 44.1, 48, 88.2, 96, 176.4, 192, 352.8, 384 kS/s and DoP (DSD/64 or DSD/128 over PCM) in USB Audio Class 2 mode, can operate in Class 1.
4x 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 & DoP/64 OR 2x Dual AES pairs at 88.2, 96, 176.4, 192, 352.8, 384kS/s & DoP/64, DoP/128 plus 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 & DoP.
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). This interface requires a compatible Word Clock input, locked to the data rate.
Wordclock I/O3x Word Clock inputs on 3x BNC connectors, accept standard Word Clock at 32, 44.1, 48, 88.2, 96, 176.4 or 192kHz. The data rate can be the same as the clock rate or an exact multiple (0.25x, 0.5x, 1x, 2x, 4x, 8x) 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. In Universal Master Mode a 38.4kHz Word Clock is available for use with the Vivaldi Upsampler.
Residual NoiseBetter than -113dB0 @ 20Hz-20kHz unweighted (6V Setting).
L R CrosstalkBetter than -115dB0, 20-20kHz.
Spurious ResponsesBetter than -105dB0 @ 20-20kHz.
