B.M.C. Audio 推出三款新機：UltraDAC, PureAmp, PureMedia

[Leo Yeh]

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

PureAmp 後級



PureAmp讓B.M.C. PureLine的產品線更為完整，其每聲道有100W輸出(8 Ohms)，本體為鋁合金，採用B.M.C.一貫的箱體設計，包括前方有個輸出顯示錶頭。PureAmp可透過B.M.C.獨有的Load Effect Free (LEF)、與B.M.C. DAC相連接，透過CI (Current Injection)，變成有如綜擴的功能。PureAmp使用了B.M.C.獨有的多項技術，包括LEF Amplification, Current Injection (CI), and Discrete Intelligent Gain Management (DIGM)，但價格非常吸引人。透過LEF Amplification技術，PureAmp一開始就可避免掉因為負回授有的失真問題。其使用了大型300W的環型變壓器，更多的能量儲存，並且比傳統A類的溫度更低，有著非常好的冷卻系統也是這麼小體積能提供這麼大輸出的原因。





PureAmp上的B.M.C.三樣專利技術
• Load Effect Free (LEF) Technology handles a speaker's current demand separately from the voltage demand. This helps the amplifier achieve high output and high-quality reproduction. It provides a top-level signal without loading the signal transistors, thus avoids distortion and increases efficiency. The result is a level of musical complexity that brings to life delicate details, rock-shaking power, high dynamics, sonic vitality, and accurate imaging.
• Current Injection (CI) Technology processes the input current from a signal source through a special XLR-CI input and the amplifier's circuitry until it attains the desired output voltage for the loudspeakers, increasing the purity of the amplified signal and the immediacy of its musical reproduction, by skipping any gain stage and using an original source signal.
• Digital Intelligent Gain Management (DIGM) is a volume and amplification control system that recalibrates gain without dividing and downgrading the input signal. It lets users adjust left/right output balances in 66 1.5-decibel increments. It also avoids unnecessary attenuation of the input signal and excessive amplification, eliminates the need for a preamp circuit, and allows a DAC or other sound sources to directly connect to the amplifier. Less amplification means less distortion and noise, which leads to a more natural musical quality





PureAmp的輸入與輸出有XLR, RCA與光纖，所搭載的遙控器也能遙控PureDAC，後方有兩組平衡XLR-CD輸入、兩組RCA輸入、兩組Neutrik SpeakOn喇叭輸出，兩組光纖輸入(B.M.C. Link)。

The PureAmp Stereo Integrated Amplifier is available Late October 2014 from authorized B.M.C. Audio dealers, B.M.C. dedicated shops and online at www.bmc.audio.de . It can be seen with B.M.C.’s other outstanding products at the Axiss hall during, Tokyo International Audio Show, Japan and at the in the Denver Mariott Tech Center, Atrium 561 during the Rocky Mountain Audio Fest.

看造型很像PA用的4PIN端子

看造型很像PA用的4PIN端子

PA擴大機常見的speakON端子。http://www.neutrik.com/en/speakon/sp...speakon-combo/

專業正解！ speakON端子

[Sound of Nature]

SpeakON端子在ProAudio是standard。用過一次後就不會再想念普通的binding post，再也不會有鬆動的接口，不會短路，鏈接速度超快！
