A professional wireless microphone system, unlike a traditional wired microphone that changes sound waves into an electrical audio signal which then goes to the sound system using a cable, converts the audio signal sent by the microphone to a radio signal which then is delivered to the sound system by a transmitter. When the transmitter picks up the radio signal, the receiver, which is always located near the sound system, is tuned to the same frequency to convert the radio signal back into an audio signal and feed it to the sound system by a cable.
Every performer using a wireless microphone at a particular location, probably a theater, church, or school, must use a system operating on a different frequency. “Frequency sharing” is impossible for wireless systems at one location because there would be interference with each other. This is similar to the situation where two television stations in the same city try to broadcast on the same channel. If two performers at one site continue trying to use the same frequency at the same time, neither voice will be picked up clearly. This is a limitation on the number of wireless mic systems that can be used simultaneously at one location. Appropriate frequencies should be selected for specific needs - reputable manufacturers and dealers of wireless systems would do you a favor.
Who benefits from such systems?
The answer is quite simple: anyone who wants to set themselves free from the restrictions exerted by cables and cords on their performance.
Musicians are allowed to use single or multi-channel good wireless mic systems to accommodate their entire bands.
Presenters could better engage the audience if they’re not clung to the podium.
Tour guides may walk into among the tourists freely to share excitement together.
Personal trainers or fitness instructors would move in an unencumbered and hands-free way.
Journalists and content creators might enjoy absolute freedom on each location.
A completely new world full of performance possibilities would be open to you once you remove the cable. The handsfree wireless microphone systems, with increasingly improved sound quality and reliability as well as decreasing cost, is now well received by the market. They are booming because they remove the microphone cable and allow you users to walk across the stage, into among the audience, and even outdoors. Under this, performers or presenters would enjoy better mobility, flexibility, and ability to talk with their hands and perform with their hands!
