Microphones are energy conversion devices that convert sound signals into electrical signals. As equipment in contact with the human body, there are ESD electrical hazards.
Standard signal maximums for microphone lines are typically 5.5 Vp-p and maximum frequencies below 10kHz.
At this frequency, the capacitance of the suppressor does not need to be considered.
This solution complies with IEC61000-4-2 air 15KV contact 8KV.
ESD protection can use discrete multilayer varistors or diode arrays.
