Handheld wireless mic systems combine the microphone and transmitter in one unit, while lavalier systems use a small clip-on microphone for discreet speech and headworn systems place the microphone near the mouth for hands-free presenting. Bodypack systems use a compact transmitter worn on the body and connect to an external lavalier or headworn microphone, giving installers flexibility for presenters, instructors, performers, and other active users.

Look for a wireless mic system with a frequency band suited to your region and installation, such as UHF ranges around 470 to 530 MHz or 530 to 590 MHz, or a 2.4 GHz system for plug-and-play operation. Helpful coordination features include automatic frequency scanning, IR synchronization between the receiver and transmitter, selectable channels, channel grouping, backup frequencies, and software-based monitoring for larger systems.

Determine the channel capacity of the receiver or linked receiver chassis, then confirm that your mixer or DSP has enough available inputs for the transmitters you plan to use. For multi-mic installations, also coordinate compatible frequencies within the system’s operating band and account for local RF congestion, since the usable channel count may be lower than the receiver’s listed capacity.

Install a wireless mic system with a receiver matched to the transmitter’s frequency band, plus the appropriate receiver antennas, often two for true diversity reception. Connect the receiver to the sound system or mixer using its balanced XLR output or unbalanced 1/4-inch output, based on the available input and the installation requirements.
