MI-8100

Example of grip installation (grip is optional)

The Directional Microphone MI-8100 is a shotgun-type directional microphone that sharply captures targeted sounds, making it ideal for simple sound source detection and ambient noise removal in abnormal sound detection.
With a flat frequency response from 50 Hz to 20 kHz and excellent directional characteristics, it can detect various sounds generated from specific areas with a high S/N ratio.

Features

  • Sharp directional characteristics that allow for clear capture of targeted sounds.

  • Achieving a flat frequency response up to 20 kHz and a sensitivity of -30 dB.

  • Realizing simple acoustic source exploration at a low cost.

  • Optimal for background noise removal in abnormal sound detection.

  • Direct connection to measurement equipment compatible with Constant Current Drive (CCLD) is possible (no external amplifier needed).

  • Features

* This product is a Directional Microphone intended for listening purposes.
Unlike omnidirectional measurement microphones used for acoustic calibration, its use for measurement evaluation is not recommended.
