The Electro-Voice RE3-HHT420-5H is a UHF wireless handheld transmitter featuring the RE420 condenser cardioid microphone head, designed for detailed vocal reproduction in live performances, presentations, and professional stage applications. The RE420 delivers rich, detailed, and full-bodied sound, with a warm and clear low end, natural and open midrange, and crisp, detailed high frequencies. Its cardioid polar pattern helps isolate the voice and improve gain before feedback. A multi-stage pop filter minimizes breath blasts and plosives, while the internal shock mount helps reduce handling noise. The microphone also features a selectable high-pass filter that reduces unwanted low-frequency content below 150 Hz when engaged. The handheld transmitter features a robust metal housing, interchangeable microphone head compatibility, and ultrasonic sync for easy frequency setup. Operating in the 560–596 MHz frequency band, it provides a 36 MHz tuning bandwidth, 1,440 selectable frequencies, and selectable RF output power of 10 or 50 mW.
