M 653

• 1/4 inch，pressure field,，175 dBA

• M 653 is a 1/4-inch prepolarized pressure-field measurement microphone, designed for extremely high sound pressure level measurement, such as blast and explosion SPL measurement.

  All microphones undergo rigorous environmental aging tests, delivering a wide frequency range, wide dynamic range, flat frequency response, and long-term stability. This enables the capture of acoustic source information across an ultra-wide frequency band.
