Headset Microphone Windscreens (Microphone Covers) The headset microphone windscreen (also referred to as a microphone cover) protects the microphone from dirt and moisture. A microphone covered by a windscreen is protected and delivers better sound quality.
The condenser microphone is built with an amplifier attached to it. The amplifier is required to operate this type of microphone. A very low-noise, high-impedance amplifier is used and it provides a low output impedance. Without the amplifier, the microphone's output signal would be so low, it wouldn't be useful. condenser microphone needs to receive an external voltage to both charge the diaphragm of the microphone so that the microphone can have charged plates (positive and negative plates) and to provide power to the amplifier.
