一款專為聲學量測、空間分析與系統校正所設計的全指向量測麥克風,核心特色在於其高度平直的頻率響應與優異的訊噪比表現。對於需要精準取得空間聲學數據的使用者而言,MM-100 能夠忠實反映環境中各頻段的實際聲壓變化,避免因麥克風本身染色而導致量測結果偏差。
MM-100 採用全指向電容式振膜設計,能平均接收來自各方向的聲音訊號,非常適合用於室內聲學量測、PA 系統調校、喇叭頻率響應分析,以及各類聲學研究用途。其 20 Hz 至 20 kHz 的寬廣頻率響應範圍,涵蓋人耳可聽全頻段,並維持線性、平坦的響應曲線,有助於後端分析軟體(如 REW、Smaart、Dirac Live 等)進行精確計算與校正。
在噪訊控制方面,MM-100 具備低於 18 dBA SPL 的殘留噪音(Residual Noise)與超過 75 dB 的訊噪比,能在低音量環境中仍保有良好的細節解析能力。同時,其最大承受音壓達 125 dB SPL,動態範圍超過 120 dB,不論是微小環境噪音或高聲壓測試條件,都能穩定工作、不易失真。
結構上,MM-100 採用全不鏽鋼機身設計,提供優異的機械穩定性與耐用度,適合長期固定安裝或頻繁外出量測使用。標準 3-Pin XLR 輸出與 +12~48V Phantom Power 供電設計,讓它能輕鬆搭配各類專業音訊介面、前級或量測系統,是一款定位清楚、規格完整、實務導向的專業量測麥克風。
