1/4inch, Free-field, 20kHz, IEPE
Overview
The M 643+A 811 is an IEPE 1/4-inch prepolarized free-field measurement microphone, which is used to measure the undistorted true sound pressure of the microphone before it is placed into the sound field.
All microphones have undergone rigorous environmental aging tests, so that they have the advantages of wide frequency range, wide dynamic range, flat frequency response and long-term stability, which can realize ultra-wide band sound source information acquisition.
