The 1/4 "measuring microphone is a transducer. The required electronics are already inserted in the MI-17. It is available % with sensitivity of 10mV/PA up to 100mV/Pa with an accuracy of ±5. Running custom versions are available. A constant current source with 2mA can be used as power supply either up to 6mA (standard version) or a stabilised power supply with 4V-30V. By default, the microphone with a BNC connector is equipped. This commercially available BNC-to-BNC cable can be used. More plug connector types such as TNC, SMB, LEMO, and µdot are available on request. The MI-17 is excellently suitable for array applications.
