A wireless microphone or a radio microphone does not require a physical cord to get connected. It is an affordable piece of equipment, which magnifies the voice so that everybody can hear it loud and clear. Wireless microphones use the same frequency range as cordless microphones, such as VHF, Gigahertz and UHF. This microphone can be of three types namely handheld, plug-in and bodypack.
How does a wireless microphone work?
In wireless systems, the audio signals of the microphone are converted into radio signals, which are directed by a transmitter via air to the receiver and then via sound system. Each wireless system has a definite amount of compatible channels that can be utilized at the same time. When operating only a particular system in a single location, one can select any wireless system available. Therefore, before selecting a wireless system one should consider the number of systems that can be added in the future.
