Omni-directional radio condenser microphone, pickup effect increased by 200% stronger filtering noise system
Effectively improve the accuracy of the pickup, sound quality is clearer, the human voice high-definition reproduction
 
Electret microphone has a small size, simple structure, good electro-acoustic performance, low price, widely used in cassette recorders, wireless microphones and sound control and other circuits. It belongs to the commonly used condenser microphone. Due to the high input and output impedance, it is necessary to set up a field effect tube as an impedance converter inside the shell of this microphone. For this reason electret condenser microphones require a DC operating voltage during operation.
 
Widely used in cassette recorders, wireless microphones and voice-activated circuits, cameras, mobile phones, video cameras, computers, sound cards, audio recorders, mixing consoles and other equipment.
