德國B.M.C. Audio (Balanced Music Concept) 一口氣推出三款新機，UltraDAC, PureAmp, PureMedia

UltraDAC



UltraDAC是PureDAC更高階的機種，擁有更具參考級的聲音品質，其是帶有平衡前級的DAC，參考等級的平衡耳擴，還有B.M.C.專有的數位智慧增益管理 Digital Intelligent Gain Management (DIGM)。UltraDAC的前級與DAC的電流/電壓轉換整合，可減少對輸出級的需求。前級與耳擴都有用上B.M.C.專有的Load Effect Free (LEF)技術，讓電流需求與電壓需求可以分別處理，自然能避免了失真的產生。UltraDAC前級與耳擴的音量控制是獨立的，搭載了高解析的非同步USB、AES/EBU, 光纖與同軸等數位輸入，平衡與RCA類比輸出，還有B.M.C. link可與B.M.C.後級連動控制。平衡輸出能與B.M.C專有的Current Injection (CI)技術的後級相容。



UltraDAC與PureDAC不同的地方
