dCS Rossini Upsampling Network DAC數位類比轉換器

Rossini Upsampling Network DAC是新一代型號中最受矚目的產品之一,因為它不單單是一台數位類比轉換器,它還具備「升頻」、「網路串流」的功能提供數位音樂玩家最尖端的技術與最方便的操作方式,最重要的是它能提昇數位音樂格式帶給您最真實感動的音質。

Rossini產品外觀延續Vivaldi的簡潔洗鍊,多了一些柔美的線條,更加新穎亮眼。

除了承襲dCS獨家的Ring DAC技術、FPGA兩倍邏輯晶片之外,它擁有市面上所有數位端子,包括工業標準規格的AES, 同軸SPDIFSPDIF光纖介面可以更簡易地連接到其他數位器材。雙AES介面可以接收來自dCS VivaldiScarlattiPaganini轉盤的「加密SACD信息」。

最特別的是,RossiniNetworkUSB狀態下都是以「非同步」模式操作,這項使用能夠使DAC在精準時鐘控制下運作,以及在數位轉類比時,不被來自電腦本身的雜訊及誤差所影響。不論您的訊源是來自CDNAS伺服器或是PC、雲端、衛星電視接收器或是iPod。甚至,目前市面上最流行的網路串流介面:TIDALSpotifyDeezer都可以搭配使用它也能支援PCM格式到達24-bit, 384kS/s並能播放原生的DSD128檔案,傳遞如同錄音室、音樂廳現場般最真實的音質。

除了電腦音樂功能,類比輸出最大值可以設定在2v或是6v,並支援64-bit數位音量控制。這項靈活的配置讓所有系統都不需要前級擴大機,實際上大大縮短了訊號鏈的距離。

dCS可程式邏輯裝置讓使用者以「軟體升級」方式下載最新版本,不論是添加新功能甚至是提昇數位格式轉變的適應力,都可以輕鬆快速地完成升級。目前亦可經由手機或是平板下載Rossini App,讓您快速方便地操作Rossini,盡情享受數位音樂帶來的美好音質。

Digital Inputs

        Network interface on an RJ45 connector – Acts as a UPnPTM renderer in Asynchronous mode, streaming digital music from a NAS or local computer over a standard Ethernet network, decoding all major lossless formats including FLAC, WAV & AIFF at up to 24 bit 384kS/s native sample rate, plus DSD/64 & DSD/128 in DFF/DSF format.

Other supported formats include WMA, ALAC, MP3, AAC & OGG.

Some formats are limited to lower sample rates. Accepts data streamed from an iPod, iPhone or iPad via Apple AirPlay, 44.1 or 48kS/s only. Network Loop Out connector on a second RJ45 connector. USB 2.0 interface on a B-type connector operating in Asynchronous mode, will accept up to 24 bit PCM at up to 384kS/s plus DSD/64 & DSD/128 in DoP format. Operates in Class 1 or 2 mode. USB-on-the-go interface on type A connector operating in Asynchronous mode, streams digital music from a flash drive at up to 24 bit 384kS/s plus DSD/64. 2x AES/EBU on 3-pin female XLR connectors.

Each will accept PCM at up to 24 bit 192kS/s or DSD/64 in DoP format. Used as a Dual AES pair, it will accept PCM at up to 384kS/s, DSD/64 & DSD/128 in DoP format or dCS-encrypted DSD. 2x SPDIF on 1x RCA Phono and 1x BNC connectors. Each will accept PCM at up to 24 bit 192kS/s or DSD/64 in DoP format. 1x SPDIF optical on a Toslink connector will accept PCM at up to 24 bit 96kS/s.

Analogue Outputs

Output levels: 2V or 6V rms for full-scale input, set in the menu. Balanced outputs: 1 stereo pair on 2x 3-pin XLR male connectors (pin 2 = hot, pin 3 = cold).

These outputs are electronically balanced and floating.

Output impedance is 3Ω, maximum load is 600Ω (10k-100kΩ is recommended).

Unbalanced outputs: 1 stereo pair on 2x RCA phono connectors.

Output impedance is 52Ω, maximum load is 600Ω (10k-100kΩ is recommended).

Word Clock I/O

2x Word Clock Inputs on 2x BNC connectors, accept standard word clock at 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 of the clock rate. Sensitive to TTL levels. Word Clock Output on 1x BNC connector. In Master mode, a TTL-compatible word clock appears on this output.

Residual Noise

24-bit data: Better than -113dB0, 20Hz-20kHz unweighted. (6V output setting).

L-R crosstalk

Better than -115dB0, 20Hz-20kHz.

Spurious Responses

Better than -105dB0, 20Hz-20kHz.

Filters

PCM mode: up to 6 filters give different trade-offs between the Nyquist image rejection and the phase response. DSD mode: 4 filters progressively reduce out-of-audio band noise level.

Upsampling Rates

DXD as standard or optional DSD upsampling.
