dCS Ring DAC APEX 新一代獨特的轉換器

獨特的 dCS Ring DAC 是所有 dCS DAC 和音樂播放器不可或缺的一部分。dCS Ring DAC APEX 是該技術的最新一代。

致力於持續發展

工程師一直在探索如何進一步增強 Ring DAC 的性能，進而提升系統提供的音樂體驗。

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。
