The Electro-Voice RE90BW is a professional full-range boundary condenser microphone designed for surface-mounted applications such as boardrooms, classrooms, video conferencing, teleconferencing, and houses of worship. Its half-cardioid pickup pattern provides excellent gain before feedback while helping suppress unwanted ambient noise. Featuring built-in equalization for a natural, balanced frequency response and advanced RF/GSM shielding, it delivers clear, intelligible speech reproduction. The ultra-low-profile design features a durable die-cast zinc housing, perforated steel grille, and a non-slip shock-isolating pad that helps minimize surface vibrations. Finished in low-gloss white, the RE90BW operates on 9–52 V DC phantom power and includes a 10-foot white shielded cable with a 3-pin male XLR connector.
