What is a wireless microphone, and how does it work?

Wireless microphone systems are designed to replace the cable that usually tethers a wired microphone (or any acoustic transducer) to an amplifier. A wireless microphone system begins with a typical microphone which responds to sound waves, and delivers essentially equivalent audio frequency electrical waves to an input of a transmitter. The transmitter "sends" a signal to an associated receiver which is connected to the input of the sound reinforcement amplifier, or mixer. The receiver "picks-up" the transmitter signal, and then converts this signal to a usable audio signal which is sent to the sound reinforcement amp or mixer.

This is a simplified description of what a wireless microphone system is, and how it works, however this becomes the fundamental basis to understanding more about this often misunderstood product.
