BARTÓK升頻數位串流DAC/耳擴

dCS很驕傲的公布了它們的Bartók network DAC and headphone amplifier-一體式,最先進的數位類比轉換器搭載了所有數位串流介面與功能再加上A類的耳擴放大器,有銀色與黑色可供選擇。

最新的dCS BARTÓK承襲了dCS的過去、現在與未來。
BARTÓK取代目前的Debussy DAC,更繼承了ROSSINI系列的DNA、Rossini Ring DAC技術、最高品質的UPNP數位串流技術以及dCS獨家的數位處理介面,在機殼內使用了獨立的電源供應。不管在技術規格,實際表現與量測下,BARTÓK是在此層級最棒的產品。


BARTÓK使用工業標準級的USB、AES或S/PDIF數位輸入來播放音樂。也能夠透過網路經由您的NAS或是網路音樂服務平台,像是TIDAL、Spodify或是Apple裝置經由Air Play來播放。Network的介面能夠完整的解碼與傳輸MQA格式。

DAC解碼的部份使用了獨立的平衡與非平衡輸出,您可以不需透過前級直接連接到後級來作使用,BARTÓK耳擴DAC搭載了標準的耳機擴大機,更使用了dCS的類比輸出針對耳機的阻抗變化加以優化。

如同所有dCS的產品,BARTÓK是由英國最高標準來設計與製造,為了減少機器內部的諧振與共振,機殼使用了航太級鋁合金。多層級的電源規範,使用了兩個主要的變壓器,並且與DAC及耳機擴大機作了相當好的隔離。內部的軟體可透過CD、USB或其他方式更新下載。這也使dCS能夠持續的增加並強化BARTÓK的功能與表現-在多年後,市場上其他對手已經過時,但BARTÓK仍在持續更新與進化。

BARTÓK將帶給您最高的享受,精確、細節以及現場音樂廳的3D還原度。BARTÓK將還原音樂內所有空氣的震動與音樂性,帶來如黑絲絨般安靜的背景與絕佳的動態表現。享受還原現場錄音與音樂不再是音響迷的專利,耳機愛樂者也可以擁有最高層次的聽覺體驗。

Digital InputsNetwork interface on an RJ45 connector – acts as a UPnP™ 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 formats include WMA, ALAC, MP3, AAC & OGG. Some formats are limited to lower sample rates. Supports Apple AirPlay at 44.1 or 48kS/s. 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/128 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 OutputsOutput levels: 0.2, 0.6, 2 or 6V rms for full-scale input, set in the menu. Balanced outputs: 1 stereo pair on 2x 3-pin XLR male connectors. 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).
Headphone Outputs1 stereo balanced pair on 1x 4-way male XLR connector. 1 stereo unbalanced pair on 1x 6.35mm (1/4”) 3-pole jack. Full-scale output levels are 1.4W rms into 33Ω, 0.15W rms into 300Ω. Output levels are 0, -10, -20, -30dB, set in the menu. Minimum headphone impedance is 33Ω.
Wordclock I/Oworldclock Io2x Word Clock Inputs on 2x BNC connectors, accept standard word clock at 44.1, 48, 88.2, 96, 176.4 or 192kHz.
