Parameters of Audio Paging Microphone - Impedance
Impedance is expressed in Ω in AC circuits. Audio signals are also considered to be AC signals because they have both positive and negative currents. The input load impedance of the mic preamp input is generally required to be greater than the output impedance of the audio paging microphone, so as to ensure the good operation of the entire system.
The total output impedance of an audio paging microphone refers to the impedance calculation of all the electronic components inside it. As a practical matter, for microphone preamps or other devices that accept microphone signals, the load impedance should be kept at approximately 10 times the output impedance of the microphone.
For any given audio paging microphone parameter table, a value describing the output impedance can be found. The output impedance of any professional microphone is 'smaller', somewhere in the range of 50Ω to 600Ω. And most of them are located between 150Ω and 250Ω.
Parameters of Audio Paging Microphone - maximum sound pressure level
Audio paging microphones have a limit on sound pressure levels, beyond which they begin to distort. This limitation is a characteristic of the microphone itself, and adjusting the gain will not affect it. Excessive sound pressure levels can damage microphones in some cases, especially aluminum ribbon microphones are greatly affected by high sound pressure levels. At the same time, some specific microphones also have pad attenuation settings, which can be used to avoid possible distortion in louder situations.
