Wireless Microphone Systems - A Primer

A wireless microphone system includes a minimum of two or three components:

1.The transmitter: Available in a self-contained handheld mic or as a belt pack with a lavalier or headworn mic, this device is a small radio (RF) transmitter. Transmitters can be fixed or variable in frequency.

2.The receiver: The receiver takes the signal from the transmitter and outputs audio to your sound system. Receivers can also be fixed or variable in frequency. It's important to note that most wireless systems can be identified by the model number and frequency band that are on the back of the receiver.

3.The microphone: Wireless handheld transmitters are self-contained. Belt pack transmitters use an external, very small microphone element which is inconspicuous. Microphones are available from Countryman and other manufacturers to replace and upgrade your existing systems. Headworn and lightweight Earset microphones are also available for the ultimate in sonic fidelity and comfort.

A wireless microphone system may also contain the following components:

1. An antenna distribution system:
When multiple wireless systems are used, it's common to have an antenna distribution system that feeds all of the receivers from one set of antennas. It's typical for these systems also to feature AC or DC power distribution to multiple wireless receivers. An antenna distribution system is an excellent upgrade when you already have three or more wireless systems. antenna distribution systems are available for almost any brand of wireless. By providing a vendor the make and model of your existing wireless systems as well as the frequency band, it is possible to make the addition to your system.

2. accessory antenna/s:
accessory antennas are commonly added for long range or very directional applications or for coordinating dozens of wireless microphones. An antenna booster is typically inserted near the antenna. accessory antennas and boosters can provide a dramatic improvement to your wireless systems.
