A wireless microphone is a microphone that does not require a physical connection to a sound system. It typically consists of a transmitter that is attached to the microphone and a receiver that is connected to the sound system. Wireless microphones are often used in live performances, as they allow the performer to move around freely without being tethered to a cable.
There are many benefits to using a wireless microphone. One benefit is that it allows the performer to move around freely. This can be important for performers who want to interact with the audience or who need to move around the stage during their performance. Another benefit of wireless microphones is that they can help to reduce feedback. Feedback is a high-pitched squealing sound that can occur when a microphone is too close to a speaker. Wireless microphones can help to reduce feedback because they do not have a physical connection to the sound system.
