How a wireless system works

A wireless system has a transmitter and a receiver. The transmitter is either a handheld microphone, a bodypack for a lavalier, headset or guitar cable, or a plug-on unit for an existing microphone. The receiver turns the radio signal back into audio for your mixer, interface, camera or amplifier. In-ear systems work the other way round, sending a monitor mix to a bodypack receiver.

Frequency bands

Wireless systems use different parts of the radio spectrum. Analogue and digital UHF systems are widely used for professional audio, with good range and many channels, but the permitted frequencies and licensing rules vary by country and change over time. 2.4 GHz digital systems use the same licence-free band as Wi-Fi and Bluetooth; they are easy to use worldwide but can be affected in crowded radio environments. Check which bands are allowed where you perform.

Choosing the right system

• Transmitter type: handheld, bodypack or plug-on
• Number of systems you need to run at once
• Range and reliability for your venue
• Automatic frequency scanning and pairing
• Latency, especially for instruments and in-ear monitoring
• Batteries: disposable or rechargeable, and run time
• Rack mounting and antenna options for larger setups

For creators and presenters

Compact clip-on systems for cameras and phones have become very popular. They often record internally as a backup and output over 3.5 mm or USB-C. Always carry charged batteries and do a sound check before filming or performing.
