The transmitter and receiver must be set to the same radio frequency for the wireless microphone signal to be sent correctly. The transmitter can be thought of like its own little radio station sending out the audio from the microphone. Interference may happen if other transmitters are sending out the same radio frequency.
This is called RF interference and can be avoided with quality wireless systems that allow us to change the transmitted frequency.
Wireless microphone receivers effectively receive the radio frequency of the microphone transmitter and convert it back to the audio signal. The receiver decodes the desired audio signal and should be connected to a mic level input of an audio console. Once again, for the wireless system to work correctly, the receiver must be set to receive the same radio frequency the transmitter is transmitting.
In VHF systems, these values are typically set so that one transmitter works with its coinciding receiver. Wireless systems come in 3 main types and have to do with how the receiver receives the transmitted radio signal. They are:. Non-diversity system receivers have one antenna to receive the signal from the transmitter.
These are rarely found in any quality receivers on the market today. Diversity system receivers have two antennas spaced a short distance apart. Both are connected to a single receiver. The wireless connection only happens between one transmitter antenna at the mic end and one receiver antenna at the receiver end. If the signal strength drops below an acceptable level on one antenna connection, the receiver will switch to the other antenna.
This switch is done blindly, and so it often improves a bad signal connection, but sometimes it makes a bad connection worse. True Diversity system receivers utilize two separate antennas, with each connected to a separate receiver module. The receiver circuitry reads both antenna signals and selects the better of the two.
At least one antennae should receive a clean signal, creating a clean signal transfer with reduced chances of dropouts. The most significant advantage is the mobility that is gained. Performers, interviewers, and speakers are given the freedom to move around naturally, which can make both the person using the microphone, as well as the audience, more comfortable.
If using a lapel mic, Countryman, or fitness headset the audio quality can be far superior as well, as it will remain equidistant from the speaker's mouth regardless of their movement. Audio drop-offs and feedback can be reduced when using these forms of wireless microphones.

For audio novices — which can include everyone from meeting planners to teachers — creating a great sounding or even merely functional microphone system without any guidance can be a confusing task.
Here are 3 things you must know before you select a wireless mic:. A functional wireless microphone system actually consists of three discreet components: A microphone, a transmitter, and a receiver. A microphone is simply the component the user speaks or sings into. It converts the sound waves into electrical impulses which can then be amplified so listeners can hear it. In a wireless mic, the electrical signal passes to a transmitter which converts the signal into radio waves.
With a handheld microphone, the transmitter is usually built into the body also known as the capsule of the mic. In the case of a hands-free microphone like a lavaliere or headset, the transmitter is usually a pack the user wears on their belt.
The transmitter broadcasts to a receiver, which changes the radio waves back into an electrical signal which can then be passed to a sound system. A good rule of thumb is to think about how far you will usually be from your subject, then doubling it to be safe. Size — Wireless systems come in a range of sizes, from ultra-compact like the Wireless GO to larger desktop units like the Performer Kit. If your system is going to be sitting in a classroom or the back of a club, something with larger controls and screen will be easier to operate.
Battery Life — Battery life is an important feature to consider when choosing a wireless mic. However, keep in mind that battery life, size and range should all be taken into consideration together. If small size is very important to you, you may have to sacrifice battery life. Or if range is your biggest concern, a larger unit may be your only option. Think about what is most important to you and make your pick to suit.
This is because transforming an analog audio signal into digital binary code during the transmission stage takes time. How much time is something you will want to investigate.
Our range offers a selection of wireless solutions for everyone from filmmakers to musicians to professionals, all built with superior components and unmatched features, delivering incredible audio quality, versatility and reliability. Wireless GO is the smallest and most versatile wireless mic system in the world. Using a Series II 2.
It also uses a Series II 2. Featuring the TX-M2 handheld condenser microphone, which pairs with a RX-DESK desktop receiver, the Performer Kit is highly intuitive, with one-touch pairing between transmitter and receiver and dual signal transmission to ensure audio is as secure as a cabled connection.
