An XLR microphone is a type of microphone that uses a three-pin XLR connector for audio signal transmission. This design allows for a balanced audio signal, reducing noise and interference, making it ideal for professional audio applications. XLR microphones are commonly used in recording studios, live performances, and broadcasting. These microphones come in various types, including dynamic and condenser models, each suited for different recording situations. Dynamic XLR microphones are durable and handle high sound pressure levels, while condenser XLR microphones are sensitive and capture a wider frequency range. Both types are essential tools for audio professionals.
