A microphone that uses a radio transmitter either inside the case of the microphone or worn as a small body pack. This radio transmitter sends the signal from the actual microphone to a receiver a short distance away so that there doesn't have to be any wires that tie down the user of the microphone.
A microphone with an FM radio transmitter inside of its case that transmits a signal to an FM receiver off of the stage area.
The wireless microphone is made up of two parts, the transmitter and the receiver. Both parts are required for the unit to function properly. You will use it to record audio when you record your video sessions with the camcorder. The wireless mic system requires one double A battery in the transmitter and receiver. Check your batteries often as this is one of the main problems why students don't have quality audio on their recordings.
A microphone system that has the microphone capsule attached to a radio transmitter. The transmitter takes the audio signal from the capsule, changes it into a radio signal, and transmits it. A matching radio receiver takes the radio signal, converts it back to an audio signal, and outputs it usually to a mixer. This is opposed to a standard microphone where the capsule is connected to the mixer by continuous wiring. The rule for using wireless mics is that if it doesn't move, it doesn't need to be wireless. Wired mics are still much, much better than even the best wireless mics.
A microphone system that uses a mic transmitter to provide cordless audio transmission to a separate receiver unit.
A microphone that has a built-in, low-power transmitter, or that is connected to a transmitter. Wireless mikes are commonly used when a mike cord would create a problem.
Consisting of radio transmitter and receiver; utilizes low-power radio signal for cable-free operation.
Invented by Hung C. Lin, the first wireless microphone went into production in 1962, called the "transistophone" and put out by the German equipment manufacturer beyerdynamic. The first time a wireless microphone was used to record sound during filming of a motion picture was on Rex Harrison in the 1964 film My Fair Lady.
