SCM Measurement Microphones
Designed for Audio Measurement Applications
SCM measurement microphones are rugged and reliable for all audio measurement environments.
The SCM-4 and SCM-4A measurement microphones are robust, free-field microphones designed for the rigorous environment of a production line without compromising the accuracy, precision, and stability required for R&D. The same microphone cartridge is used in both models; the only difference is the length and weight. The SCM-4 is our standard microphone and the SCM-4A is a short version designed for production line use in confined spaces, and is a dimensional replacement for other popular microphone brands.
The SCM-4 contains a 1/4” pre-polarized condenser cartridge with a gold diaphragm for sensitivity and stability. Its rugged stainless steel protection grid shields it from rough operator handling and the high humidity and temperatures of industrial environments to ensure long operating life. It offers excellent omni-directionality in both the near field and far field which makes it suitable for many different test configurations.
Each microphone is calibrated before it leaves our facility, and calibration correction curves are available on request in formats suitable for importing into SoundCheck® or other test systems.NIST and other traceable calibrations are available upon request.
* Note: The SCM-4 is the successor to our popular SCM-3 and features improved dynamic range (THD), but is otherwise identical in performance and dimensions to the SCM-3. It handles SPL up to 126dB with <1% THD, an enhancement over the 123dB offered by the SCM-3.
