經過廣泛的研究和開發,dCS對 Ring DAC 硬件進行了一些重大更改,重新配置了 Ring DAC 電路板並開發了全新的模擬輸出級。 
這使我們能夠減少失真,改善線性度,並在一系列關鍵領域提供測量和主觀的改進,將 Ring DAC 的世界領先性能提升到一個新的水平。它還使我們能夠進一步增強備受喜愛的 dCS Vivaldi DAC、dCS Ring DAC APEX 和 Rossini Player 的性能。

dCS Ring DAC APEX 主要特性
  • 最新一代 dCS 數字處理平台帶來最先進的信號處理和靈活性
  • dCS Ring DAC APEX,用於 Vivaldi 播放系統,提供增強的聲音和技術性能
  • 通過 dCS Mosaic Control 應用程序從 TIDAL、Qobuz、Deezer 和互聯網廣播中獲得高質量流媒體
  • Roon Ready、AirPlay、Spotify Connect 和 UPnP 兼容
  • USB、AES、雙 AES 和 S/PDIF 數字音頻輸入。
  • 通過雙 AES 輸入接受來自 dCS Transport 的加密 SACD 數據
  • 多級DXD過採樣設計,可選DSD上採樣;用戶可選擇的 DSP 和 DSD 濾波器。
  • 自動時鐘系統提高了易用性並最大限度地減少了抖動。
  • 多級功率調節和雙電源變壓器隔離模擬、數字和時鐘電路。
  • 固件可升級以用於未來的功能和性能升級。
  • 具有完整的 MQA™ 解碼器。這種 MQA™ 實施是獨一無二的,因為它是第一次啟用 DAC,通過提供超過 16x (768 kHz) 的精確渲染,以非常低的調製噪聲匹配所需的時間響應。

數位類比轉換方式dCS proprietary Ring DACTM topology.
數位輸入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 or DSD/128.
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.
類比輸出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).
時鐘輸入/出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 Noise24-bit data: Better than -113dB0, 20Hz-20kHz unweighted. (6V output setting).
L R CrosstalkBetter than -115dB0, 20Hz-20kHz.
Spurious ResponsesBetter than -105dB0, 20Hz-20kHz.
FiltersPCM 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.
升頻選項DXD as standard or optional DSD, DSDx2 upsampling.
