Class 1 – WS2F – DIN IEC 61094-4
The 1/2″ measurement microphone MP30-Infra makes it possible to use a high-quality, pre-polarized measurement microphone capsule MK 222 E on measurement systems with IEPE supply. Typical applications include low-frequency measurements.
The MP30 preamplifier is designed with a frequency response of 0.1 Hz to 200 kHz and can be fitted with a microphone capsule suitable for the application.
The MI-MKAL microphone holder is recommended for mounting the microphone. The use of 1/2″ measuring microphone capsule accessories, such as windscreens etc., is possible without any problems.
The measuring microphone can be calibrated with the sound calibrator 4010, CA 111 or with other suitable sound pressure calibrators.
