MUTEC 已經投入了自己的研究，以發現通過 USB 傳輸高端音頻的基本原理和問題根源。簡而言之，任何形式的電磁干擾，特別是由音頻計算機和其他 IT 設備引起的電磁干擾，都會產生噪聲並嚴重干擾音頻傳輸。 為了消除這些干擾並儘可能避免對轉換過程造成破壞性影響，MC-3 + Smart Clock USB(智能時鐘)研發了一種新的信號隔離，異步 USB 接口。
產品特色:
優化受抖動影響的數字源，例如CD傳輸，衛星比率和長距離電纜; 非常適合用作信號調理器，以改善任何D/A轉換器
通過USB以最高保真質量啟用計算機音頻; 用作數字音頻切換矩陣格式，轉換器和主時鐘; 從計算機導出和轉換本地DSD信號; 將USB音頻流隔離到數字設備; 改善受抖動影響的數字源，以用於存檔和音頻處理。
USB 接口是在基於計算機的音樂播放環境中用於數字音頻傳輸的最常用的設備。但是，便利性和易用性常常以對高端消費者音頻愛好者和專業用戶的聽覺不佳的音頻質量為代價。眾所周知，即使最好的 D/A 轉換器也無法通過 USB 盡可能高的電平再現和轉換音頻，這就是為什麼使用數字音頻輸入(例如 AES3 或 S/P-DIF)產生明顯更好的結果的原因，並且通常首選。
它被設計為專用的構建模塊，其電源獨立於設備的主板。此外，USB 接口與電路的其他部分電氣隔離，並採用自己的超低噪聲音頻振盪器，該振盪器又是自主的並與其他過程隔離。 結合基於 IT 的高速隔離器，已極大地降低了 USB 數據流中噪聲干擾的影響，從而產生了 USB 接口，幾乎不受 PC 電腦、筆記本電腦或音樂服務器引起的任何干擾問題的影響。同時，對於使用 MC-3 + USB 從音樂庫播放的時鐘速率，沒有任何限制，支持最高速率的所有頻率，包括高速 USB 以及 DSD/DoP 流，最高可達 DSD/DoP256。
獨特的表位透明重新恢復計時，無需常規採樣頻率轉換即可獲得最純淨的音質; 發燒友，異步兩通道 USB 接口，具有超低噪聲音頻時鍾振盪器，總電隔離高達2500VRMS(分別為 4242VPK)，用於抑制高頻干擾; 以可選的輸出時鐘速率將 DSD/DoP 流(64-256)轉換為 PCM 音頻; 鎖定 MUTEC 的 REF10 以及原子鐘和 GPS 時鐘參考; MUTEC 改進的下一代 REVIVE 重新恢復計時和 1G 時鐘技術; 經過測試和認可，可為 Roon 提供一致的出色用戶體驗。
