The Gemini Sound UHF-04M, 4-channel wireless microphone system that features four handheld microphones with cardioid polar patterns. This means that the microphones will pick up sound primarily from the front, while minimizing any noise from the sides or rear. The system has an operating range of up to 150 feet, so you can move around freely while you’re performing. The microphones also have a dynamic range of 110dB, which means that they can handle a wide range of sound levels without distorting.
