Wireless Microphone Components
The Microphone
This is the actual part of the system that transforms your desired acoustic sound into an electrical signal. In most cases it will be a handheld microphone, lapel (clip-on) microphone or the newer countryman style microphone.
The Transmitter
This device takes the electrical signal and wirelessly transmits it to the receiving end. This is generally placed on the belt/pants of whomever is using the microphone. Some microphones actually have the transmitter built right in, so there is no belt pack required.
The Receiver
This piece of equipment is physically the largest part of the wireless system. It is best to place this as close to your stage as possible, to achieve the strongest signal and the best quality. Sometimes it is just more convenient to have it back at the soundboard, but beware, it may pickup interference from your power amplifiers and other electrical equipment.
