Measuring and Judging the Performance of Moving-Coil Microphone (MIC) Cartridges
2. Set the multimeter to the DC 50uA range or another smaller current range. Connect the probes to the two output terminals of the cartridge coil. Blow air towards the diaphragm with your mouth and observe the needle deflection. A larger amplitude indicates higher cartridge sensitivity and better performance. Conversely, it indicates poorer performance.
The above methods can only provide a preliminary judgment of moving-coil microphone cartridge performance. For microphones used in different scenarios, actual comparative measurements are required to determine their superiority.
Note: The above tests were conducted using an analog pointer multimeter.
