Electro-Voice RE90H
Condenser Cardioid Hanging Microphone, Black.


The RE90H and RE90WH of the Architectural Microphone Series are back electret condenser hanging microphones providing an extended, flat frequency response with a controlled cardioid polar pattern for high-quality sound reinforcement. The RE90H is specifically designed for live pickup of choirs, instrumental and vocal groups, and theater. The size and color of the transducer and cable allow the microphone to blend in with its surroundings.The RE90H’s low self-noise and high-out-put signal level combine to produce low-noise, sound-reinforcement and recording. Exceptionally high sensitivity, a uniform car-dioid polar response, and smooth frequency response make the RE90H ideally suited for distant sound pick-up. The cardioid polar pattern is precisely controlled and is highly effective in suppressing feedback without coloration of sound. Power for the RE90H is obtained from any phantom source supplying 9 to 52 volts. The RE90H is furnished with 25 feet of black (RE90H) or white (RE90WH) miniature braided shielded cable. The design of the cable ensures the microphone’s horizontal position will be held stable without the need for fish-line tethering.The RE90H is easily aimed at the performance with the supplied steel wire hanger and holding nut. The wire hanger attached to the microphone element and cable can be bent to aim the microphone in the vertical plane. To position the microphone on the horizontal plane, loosen the holding nut on the back of the microphone and slightly twist the microphone on the wire holder (clock-wise rotation rotates the RE90H to the left; counterclockwise rotation rotates the RE90H to the right). Secure this position by tightening the holding nut. Note: For fixed installations, allow the microphone cable to hang for at least 24 hours so the cable can completely relax and establish a set. This allows the microphone to be accurately positioned over a choir, stage or orchestra.
