General Description (cont’):
The bass-boosting proximity effect common to most directional
microphones when used close to the sound source, is eliminated
in the RE20. This is accomplished via the application of the EV-
exclusive Variable-D® technology. By controlling the effect of
microphone proximity, the RE20 can be located very close to sound
sources without a loss in clarity or definition making the RE20 ideal
for tight vocals and challenging instruments. It can be used inside
bass drums, on acoustic guitars, and is found in voice booths and
broadcasting studios everywhere.

Specifications:
The microphone shall be a cardioid type with integral blast filter
protecting all acoustic openings. The blast filter shall also serve as
a shock mount for the internal microphone element. The microphone
shall have a wide-range uniform frequency response from 45-
18,000 Hz. An integral passive network shall be provided so that
when the filter switch is in the “on” position, low-frequency response
shall tilt down 4.5 dB from 400-100 Hz. With switch in “off” position,
microphone shall be essentially “flat” from 80-6,000 Hz, with a broad
2.5 dB rise in response from 6,000-14,000 Hz, and nominally down
3 dB at 18,000 Hz. Response below 80 Hz shall be nominally down
3 dB at 45 Hz. Output level shall be 1.5mV/Pascal. Nominal
impedance of 150 ohms. Response at any angular position away
from the major axis shall be essentially similar to the response
on the major axis, but attenuated uniformly at all frequencies by an
amount appropriate to that angular position. Attenuation at
frequencies from 45-10,000 Hz (refer to major axis signal value)
shall exceed 15 dB at 180° from major axis in any plane. Attenuation
above 10,000 Hz shall exceed 13 dB. Polar characteristics shall
be sufficiently uniform in all planes so that it is, effectively, a cardioid
of revolution. There shall be a shield to prevent dust and iron
particles from reaching the diaphragm. The case shall be made of
steel. The microphone shall have a maximum diameter of 54.4
mm (2.14 in.), a body diameter of 49.2 mm (1.94 in.) and a length
of 216.7 mm (8.53 in.). Finish shall be a nonreflecting fawn beige.
A stand adapter shall be supplied. The Electro-Voice RE20 is
specified.
