XLR connectors (mid-50s to today) Most commonly used on professional microphones, the common 3-pin XLR connector is a standard for transferring balanced audio among professional audio equipment. The 4-pin XLR is the standard connector for intercom headsets, such as systems made by Clear-Com and Telex. Two pins are used for the mono headphone ...
An electret microphone is a microphone whose diaphragm forms a capacitor (historically-termed a condenser) that incorporates an electret. The electret's permanent electric dipole provides a constant charge Q on the capacitor. Sound waves move the diaphragm, changing the capacitance C, which produces a corresponding voltage change across the ...
