General Description:
Technical Specifications:
Generation Element: Condenser, back electret
Frequency Response: 75 Hz to 15,000 Hz (see chart)
Polar Pattern: (see chart) Cardioid
The Electro-Voice® RE90H and RE90HW of theArchitectural
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. RE90H’s low
self-noise and high-output signal level combine to produce
low-noise, sound-reinforcement and recording. Exceptionally
high sensitivity, a uniform cardioid 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 (RE90HW) 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 (clockwise rotation rotates
the RE90H to the left; counterclockwise rotation rotates the
RE90H to the right). Secure this position by tightening the
holding nut.

Net Weight: 157 g (5.5 oz.)
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.
