RME 歷來最強大且便攜的 Audio USB 錄音介面 - FireFace UCX II

RME 最新的即插即用技術保證了即使對於無經驗的用戶也能簡單安裝。許多獨特的功能，如精心設計的 Routing Solution 等，實現了 Fireface UCX II 的快速、舒適和高效操作。

Fireface UCX II 在前面板上設有兩個麥克風 / Line Pre，配置為 XLR 組合插孔，接著是兩個數位控制的線路/儀器輸入，然後是一個耳機插孔，各種控制按鈕，一個顯示器，和主音量旋鈕。在後部是一組十個模擬平衡線路輸入和輸出，MIDI I/O，ADAT I/O，AES/EBU 和 SPDIF I/O，USB 2.0 以及一個可切換的 Clock I/O ，藉著 SteadyClock FS，Fireface UCX II 擁有 RME 最新的時鐘和 Steady 穩定技術。

完全獨立作業

直接從前面板控制所有設備狀態，方便直接切換功能。四個按鍵和 Encoder ，高分辨率和清晰的彩色顯示器，以及全新設計的作業系統。此外，內部記憶體允許存儲六種不同的運作狀態。因此， Fireface UCX II 能夠完全獨立操作，無需連接任何設備。在獨立操作中，它可以通過簡單地按一下按鈕轉變為完全不同的設備。此外，TotalMix FX也可以通過MIDI進行控制。

40 Channels

DURec 是一個集成的數位錄音裝置，可以直接通過後部 USB 端口將所有輸入和輸出錄製到 USB 存儲設備。它允許在最大 2TB 容量的 USB 隨身碟或硬碟上錄音。錄音功能由內部 DSP 提供，因此無需連接外部設備。此 USB 端口可以選擇用於直接連接 RME 的 ARC USB 遙控器。

包含強大的混音，監聽和測量應用程式

Fireface UCX II 配有 TotalMix FX DSP 作業系統，提供全面的 Routing 和 Monitoring 選項，以及 DIGICheck 分析器，允許以最大精度測量和分析雙向的數字數據供應。TotalMix FX 可以完全替代外部混音器，使得可以為任何輸出（包括主監聽和音樂家的耳機混音）創建多個無延遲的監聽混音，並帶有 EQ，動態，混響和延遲。

CV/Gate電壓控制

大多數音頻接口都是傳統設計的，稱為 ""DC Coupled Output" ，其中使用電容器過濾掉任何極低頻率。

Fireface UCX II 的所有 Line Output 都是 DC Coupled ，允許發送控制電壓（CV）或 Gate 訊號到模組化合成器（如流行的Eurorack和Moog/MOTM/Synthesizers格式）和其他工作室設備。
