Microphones are electronic devices used for capturing sound waves and transforming them into electric signals. The EA-21842 is a type of microphone designed for commercial and professional use applications. It is an omnidirectional microphone with a cardioid frequency response, making it ideal for live performances, sound studios, and broadcast applications.

The EA-21842 is equipped with a Class-A, cardioid condenser capsule, a transformerless, ultra-low output impedance design, and a wide frequency response of 20 Hz – 20 kHz. It has a sensitivity of -32 dB and a maximum SPL of 130 dB. Furthermore, the capsule is protected by a built-in foam windscreen, making it suitable for capturing sound in high wind situations. The low noise preamplifier provides a balanced line output, with a high common mode rejection ratio and low self-noise of only 11.3 dBA. It also features an adjustable low-cut filter that helps reduce unwanted background noise.

The working principle of the EA-21842 is based on the electro-mechanical transduction of sound waves. When sound waves enter the capsule, the diaphragm that covers the capsule membrane vibrates and generates an electric signal. This electrical signal is then amplified by the preamplifier and sent to the output.

The EA-21842 is designed for capturing sound in live performance and broadcast applications. Its cardioid frequency response allows it to reject sound from the rear, making it ideal for isolating sounds from the front without disrupting sound from the rear. It is also well-suited for sound studios, as it is capable of capturing sound with precision and clarity. In addition, its low output impedance design helps reduce noise and eliminate crosstalk. It is also suitable for recording dialogues, interviews, lectures, and other applications where high-quality recordings are required.

The EA-21842 is an excellent choice for commercial and professional applications. Its wide frequency response, high sensitivity, and low self-noise make it an ideal microphone for capturing sound with detail. Its robust construction and low output impedance make it reliable and durable, and it is easy to use and maintain.
