What is a wireless microphone system?<\/h2>\n\n\n\n
Before we start setting up the wireless system, let\u2019s quickly discuss what these systems are and how they work. A wireless system is essentially a miniature radio station that replaces either a microphone cable or an instrument cable. The transmitter sends radio frequency<\/a> (RF) to a receiver, receiving the signal and then sending the audio over to your mixer. Wireless systems are very common in places such as houses of worship, fitness centers, sporting events, and concerts because they give performers more freedom. They also save time and space by eliminating the need to use and hook up many cables.
<\/p>\n\n\n\n\n\n\n\nParts of a wireless microphone system<\/h2>\n\n\n\n
Although wireless setups can differ, all are comprised of the same components: transmitters and receivers. The terminology can be confusing, so let\u2019s describe the parts and what they do.
<\/p>\n\n\n\nTransmitter<\/h3>\n\n\n\n
The transmitter converts audio (AF) from an input device, like a handheld or headset microphone, into radio frequency (RF), then sent to the receiver. If you are using a microphone or instrument connected to a belt pack with an external antenna, make sure that the antenna isn\u2019t wadded up or bent while wearing it. Not only is this bad for the antenna, but it severely impairs its transmission.<\/p>\n\n\n\n
Receiver<\/h3>\n\n\n\n
The receiver is the box with antennas that you connect to your mixer. It receives the radio signal, changes it back into an audio signal, then sends it to the input of your mixing board using either an XLR or instrument cable.
<\/p>\n\n\n\nChoosing and using batteries<\/h4>\n\n\n\n
Signal strength and operating range will drop as the transmitter (or, in the case of in-ear monitors, the receiver) batteries run low, so changing them regularly will significantly reduce performance issues. We highly recommend using brand-name alkaline batteries (either rechargeable or non-rechargeable), as they are more reliable<\/a> and provide longer life than generic batteries.

Parts of a basic wireless system.<\/em>
<\/p>\n\n\n\n\n\n\n\nWireless microphone system setup<\/h2>\n\n\n\n
Now that you know what a wireless system is and how it works let\u2019s talk about setting it up and using it. There are three main steps involved in setup:<\/p>\n\n\n\n
- Install the receiver<\/a><\/strong><\/li>
- Pair the transmitter and receiver<\/a><\/strong><\/li>
- Set the volume for the system<\/a><\/strong><\/li><\/ul>\n\n\n\n
Install receiver and antenna<\/h3>\n\n\n\n
Installing the receiver and antenna should be the first step when setting up your wireless system. It\u2019s usually convenient to keep the receiver close to the mixer, but the \u201cright\u201d location is wherever the transmitter will have a direct path to the receiver without any blockage from people, computers, racks of gear, or anything else. Follow these instructions to install your receiver and antenna.<\/p>\n\n\n\n
- Place the receiver where the performer(s) will have a consistent, direct line of sight to the receiver at least 10 feet away from wireless consumer devices such as wireless computer routers and cell phones, as this will reduce dropouts and audio artifacts like static and feedback.<\/li>
- Install the antenna, and point it toward the ceiling. If your receiver has more than one antenna, angle them to form a V shape.<\/li>
- Connect the output of your receiver to an available input channel on your mixing board, then power the receiver on.<\/li><\/ol>\n\n\n\n
Antenna and receiver placement tips<\/h4>\n\n\n\n
- Make sure the antennas are pointed at the ceiling and not out toward the stage. An antenna\u2019s polar pattern looks like a doughnut, so if it is pointed straight out, very little radio frequency will reach the transmitter.<\/li>
- Make sure metallic objects, such as rack rails or metal cages, aren\u2019t blocking antenna(s), as this stops the radio waves from being sent out correctly.<\/li><\/ul>\n\n\n\n

Pair transmitter and adjust the frequency<\/h3>\n\n\n\n
Before you begin the pairing process, make sure the frequency range of your wireless system is compatible in your area. If you aren\u2019t sure of the correct frequency range, use a wireless system frequency finder<\/a> to verify compatibility.<\/p>\n\n\n\n
Auto-scan<\/strong>: Some wireless microphone systems have an auto-scan feature. This will scan all frequencies, groups, and channels to find the best available frequency. To perform an auto-scan, visit the owner\u2019s manual for instruction.<\/p>\n\n\n\n
- The next step is to pair the transmitter and receiver. The pairing procedure is different for every wireless model, so check the owner\u2019s manual to learn your system\u2019s pairing procedure. Here are the two most common ways wireless systems pair:
- Group and Channel will pair to the range of frequencies in that particular band<\/a>.<\/li>
- Frequency is tied to the exact wireless frequency.<\/li><\/ul><\/li>
- Confirm that the transmitter and receiver have been paired by looking at your receiver’s RF meter or LED. If the RF signal meter or LED is flashing or low, consider trying a different frequency.<\/li><\/ol>\n\n\n\n
Make sure you’re on the right frequency!<\/h4>\n\n\n\n
- When using more than one wireless system, use different frequencies for each one. Multiple systems on the same frequency can cause distortion, dropouts, or multiple mics on the same channel as your mixer.<\/li>
- Check your frequencies before each performance. Even if your system always stays the same, interference from radio and TV stations can change on a regular basis.<\/li><\/ul>\n\n\n\n
