Bodypack transmitters clip to clothing and connect to a separate microphone, such as a lavalier, while handheld transmitters combine the microphone and transmitter in one unit. Boundary-style transmitters sit on a surface and capture speech nearby, which can suit meetings or presentations around a table.

Choose a transmitter form factor that fits the setup: boundary transmitters can suit fixed conferencing positions, while bodypack transmitters pair with a lavalier microphone and handheld options suit presentations or live audio. Check that the transmitter matches the wireless receiver system, and consider the microphone type and how speakers will move during use.

Compare each wireless sound transmitter’s compatibility with the receiver, wireless band or protocol, and form factor, such as boundary, bodypack, or handheld. Also check the microphone connection or capsule type and pickup pattern to match the speaker, room, and installation needs.

Plan for the number of microphones that need to operate at the same time, then match the transmitter count to the compatible receiver system’s channel capacity. Choose handheld, bodypack, or boundary transmitters based on how each person will speak and how the microphone will be used.
