All wireless microphone systems, regardless of their applications, consist of two main parts: transmitters and receivers. Transmitters convert the audio signal captured by the mic into a radio signal. These are then sent to a receiver that converts them back to an audio signal, which is then sent to the sound system.
First, we’ll look at the different types of mic transmitters.
Handheld Microphone Transmitters
These wireless mics incorporate the transmitter into their handle so both functions are contained in a single unit. The Alvoxcon CK & UM series come with this kind of handheld microphones. As with wired handheld mics, there are numerous wireless dynamic and condenser mic models to choose from that will match just about any performer’s needs. Some manufacturers offer separate transmitters that can be plugged into the XLR connector of any dynamic mic, making microphone options even more plentiful when going wireless.
These units clip onto clothing (collar) and can be used with lavalier or headworn vocal mics:
Lavalier vocal mics usually attach to clothing, come in a range of sizes, and are used to capture dialog in TV and film production as well as for some public speech applications.
Headset vocal mics deliver consistent, quality sound pickup, have a headband, and are easy to position for use during highly active performances.
Wireless Microphone Receivers
The receivers are used to connect to your other devices such as mixers, amplifiers, and speakers. Most receivers come in shape of cuboid with to fit the IEA 19” rack mount. Now new design of receivers entered the market, namely “Mini Rechargeable Receiver” it comes with small size, 1/4” Plug, which can be plugged into any device equipped with 1/4” MIC IN jack, that is a great idea for non-professional applications.
