  M190-Si

   Acoustics Measurement Microphone

      


Characteristics


-The appearance is compact and exquisite, and the installation is simple.

-Provide 9-48V phantom power input.

-Suitable for testing sound fields and PA system calibration.

-Provide individual measurement caliberation file, with USB flash for each MIC.


Functions


  1. It can be used as an ideal spectrum analyzer, allowing for monitoring of frequency response and sound pressure levels of speakers. Compact in appearance, it can be installed inconspicuously.

  2. The linear casing and remote installation of the microphone have a very low impact on the sound field, which can avoid the increase of high-frequency sound pressure.

  3. Receive precise linear frequency response in a diffused sound field.
