You see wireless mics at almost every stage event you attend. This particular piece of technology has shaped the live entertainment industry today—no more tripping over cords on stage or being abruptly pulled back when you reach the end of the leash. It may seem complicated, but the science and engineering behind wireless mics is pretty easy to understand. Take a look below. 

The Transmitter

The transmitter is the part of the microphone that sends a message via radio waves. A section of the radio wave frequency spectrum is specifically designated for wireless transmitter use. The waves cut through static and interference at a specific range of frequency divided in low band and high band. For regular wireless mics that look like the handheld devices a standup comedian might carry, the transmitter is built directly into the mic. Small clip-on mics worn by news reporters and people who need full use of their hands require a small transmitter box to also be worn by the speaker.

The Receiver

The transmitter would be useless without somewhere to send the message. That’s where the receiver comes in. The receiver picks up the message sent by the transmitter and converts those waves into the live audio that comes from the speaker. It’s possible to have either a single-channel receiver or a multi-channel receiver. Multi-channel receivers are used when more than one wireless mic is active. If you’re planning an event and require instrument rental, you’ll be provided with the receiver as a separate piece of equipment from the microphone.
