A microphone (from the Greek μικρός – small, φωνη – voice) is an electro-acoustic device that converts sound vibrations into electrical ones and is used to transmit sounds over long distances or to amplify them in telephones, broadcasting and sound recording systems. The most common type of microphone and at the moment is a dynamic microphone , the advantages of which include their good quality indicators: strength, small size and weight, low susceptibility to vibrations and shaking, a wide range of perceived frequencies, which makes it possible to use this type of microphone as well as in studios and outdoors when recording open concerts and reports In this article, the experts of the store “Student” will tell you how to…
