The SCM 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 5.4 mm prepolarized condenser cartridge incorporates a gold vertically mounted diaphragm specially designed to withstand high humidity and temperature conditions often found in many production environments.

Individual calibration charts* are supplied with each microphone along with the calibration data on a 3½ inch floppy disk. The data formats are ASCII text and the DAT format used by the Listen SoundCheck™ software.

NIST and other traceable calibration available upon request.
