The Electro-Voice RE3-HHT520-6M is a UHF wireless handheld transmitter featuring the RE520 condenser supercardioid microphone head, designed for expressive vocal performances, presentations, and demanding stage applications. The RE520 delivers detailed, full, and vivid vocal reproduction, with a warm and tight low end, natural and present midrange, and crisp, exceptionally detailed high frequencies. Its supercardioid polar pattern provides excellent acoustic isolation and helps maximize gain before feedback, making it suitable for loud stage environments. A multi-stage pop filter minimizes breath blasts and plosives, while the internal shock mount helps reduce handling noise. The selectable 150 Hz high-pass filter reduces unwanted low-frequency content when engaged. The handheld transmitter features a robust metal housing, interchangeable microphone head compatibility, and ultrasonic sync for easy frequency setup. Operating in the 653–663 MHz frequency band, it provides a 10 MHz tuning bandwidth, 400 selectable frequencies, and selectable RF output power of 10 or 20 mW.
