KABR M320 Microphone Specifications

The KABR M320 is a 1/2-inch free-field microphone. It features excellent corrosion resistance, sturdiness, and extremely high stability, making it suitable for measurements in non-reflective free-field and semi-free-field environments. Adopting a pre-polarized design, it requires no external polarization voltage and is compatible with preamplifiers powered by ICCP.

The KABR M320 utilizes a post-equalization method, with a frequency range of 3.15 Hz to 20 kHz and the ability to measure sound pressure levels (SPL) up to 146 dB. It is ideal for high-precision general acoustic measurements and can also be used with instruments such as sound level meters, multi-channel analyzers, noise analyzers, and electroacoustic testers. Each KABR M320 comes with an independent calibration data sheet before leaving the factory, which includes information such as sensitivity and frequency response.
