The system uses UHF wireless technology for a stable signal and reduced interference.
It typically includes two wireless handheld microphones and a receiver.
The microphones often feature a cardioid pickup pattern to minimize background noise and focus on the speaker's voice.
Operating distances can range significantly, with some systems offering up to 30-50 meters (98-164 feet) of reception range.
The receiver usually connects to a sound system via a 6.35mm (1/4 inch) jack port.
