The EA-21842-G17 is a microphone designed for live sound reinforcement or broadcasting applications. It has a directional cardioid polar pattern that helps to reduce feedback and lift off issues while providing excellent clarity and sound quality. The EA-21842-G17 offers good low frequency response and rejection of background noise. The microphone requires +48V phantom power to operate.
Application Field
The EA-21842-G17 is designed for sound reinforcement in live environments such as concerts, conferences, theater, sporting events, and stage shows. It can also be used in the studio for voiceover work or broadcast applications. The cardioid polar pattern is designed to reject off-axis sound, making it ideal for these types of applications.
Working Principle
The EA-21842-G17 uses a pressure-gradient transducer to convert sound pressure into an electric signal. A pressure-gradient transducer consists of two sides of the transducer diaphragm, one open to the sound pressure and the other closed to the back chamber. The open side contains a back plate, which acts as a sound pressure reference. When sound pressure waves enter the microphone, the two sides of the transducer move relative to each other, creating a proportional electrical current. The electrical current is then amplified and sent to the output of the microphone. The polar pattern is controlled by the shape of the microphone capsule and the spacing of the two sides of the transducer diaphragm.
Conclusion
The EA-21842-G17 is a microphone designed for live sound reinforcement or broadcasting applications. It has a directional cardioid polar pattern that helps to reduce feedback and lift off issues while providing excellent clarity and sound quality. It requires +48V phantom power to operate and uses a pressure-gradient transducer to convert sound pressure into an electric signal. Overall, the EA-21842-G17 is a great choice for applications requiring good sound quality, low frequency response, and good background noise rejection.
