The Electro-Voice RE3-HHT420-5L is a UHF wireless handheld transmitter featuring the RE420 condenser cardioid microphone head, designed for expressive vocal performances, presentations, and professional stage applications. The RE420 delivers rich, detailed, and full-bodied vocal reproduction, with a warm and clear low end, natural and present midrange, and an open, crisp high end. Its cardioid polar pattern provides excellent acoustic isolation and helps reduce feedback. A multi-stage pop filter minimizes breath blasts and plosives, while the selectable high-pass filter attenuates frequencies below 150 Hz to reduce unwanted low-frequency content. The microphone also features an internal shock mount to minimize handling noise. The handheld transmitter has a robust metal housing, interchangeable microphone head compatibility, and selectable RF output power. Operating in the 488–524 MHz frequency band, it provides a 36 MHz tuning bandwidth, 1,440 selectable frequencies, and selectable RF output power of 10 or 50 mW.
