Neumann M149 真空管電容麥克風
Neumann M149 是一款通用錄音室話筒,具有傳奇般的 M 49 的傳統電子管電子管,大振膜電容話筒在 1950 年代提高了錄音標準,並塑造了無數爵士樂和流行專輯的聲音。 M 149 延續了這一傳統,通過更新的技術和改進的性能規格增強了其前身的永恆保真度。

M 149 使用與其著名的前身相同的聲音傳感器,經典的 K 47/49 大振膜極頭,以其卓越的平衡性和無與倫比的臨場感而聞名。這種精緻的雙振膜極頭安裝在一個大型的聲學開放式頭罩中,可最大限度地減少內部反射。然後,極頭信號由超小型三極管放大,專為最低噪聲和最佳傳輸特性而選擇。最後一級是一個高精度、超低失真的無變壓器輸出級,它保留了前面電子管電路的全部動態,並針對 21 世紀的信號鏈進行了優化。與老式電子管話筒相比,M 149 具有更高的靈敏度和更低的噪音。並感謝其電流傳感技術,可確保管的最佳運行條件,憑藉其低輸出阻抗,M 149 可以驅動長達 300 m 的長電纜,而不會造成傳輸損耗。正是這種經典管技術與最先進的諾依曼工程技術的創新結合,使 M 149 於 1997 年獲得了著名的 TEC 獎。

The M 149 uses the same sound transducer as its famous predecessor, the classic K 47/49 large diaphragm capsule, renowned for its supreme balance and unmatched presence. This delicate dual diaphragm capsule is housed in a large, acoustically open headgrille, which minimizes internal reflections.
The capsule signal is then amplified by a subminiature triode tube, specially selected for lowest noise and optimal transmission characteristics. The final stage is a high-precision, ultra-low distortion transformerless output stage, which preserves the full dynamics of the preceding tube circuit and is optimized for 21st century signal chains.
