Key Features:

• Favorite of broadcast show hosts and voice-

over studios

• Ideal for instrument recording, especially

kick drums and acoustic guitars

• Studio condenser response yet no powering

required and immune to overloading

• Large Acoustalloy diaphragm and low-mass

aluminum voice coil

• Dual-ported, continuously Variable-D® with

minimal proximity effect

• Steel case and hum-bucking coil provide

exceptional magnetic shielding

The Electro-Voice RE20 is a professional-quality dynamic

cardioid microphone created specially for recording, broadcast

and sound-reinforcement applications requiring essentially

flat response over a very wide frequency range. The wide

frequency response, coupled with excellent transient

response, make the RE20 easily comparable to the finest

condenser cardioid microphones and an easily operated “bass

tilt down” switch corrects spectrum balance for use in long-

reach situations or other applications where bass attenuation

is needed.

A true cardioid microphone, the RE20 offers greatest rejection

at 180º off axis - directly to the rear of the microphone. Pattern

control is so consistent that the frequency response is nearly

independent of angular location of the sound source, creating

virtually no off-axis coloration, yet providing greatest possible

rejection of unwanted sounds. An integral blast and wind filter

covers each acoustic opening on the RE20. In recording

sessions or on stage, singers can “close talk” the microphone,

singing with their lips almost touching the grille screen with

no worry of “P-pops” or excessive sibilance. Part of the filter

also shock mounts the internal microphone element, reducing

the transfer of vibrations from external sources. The

exceptional performance of the RE20 is achieved by using a

large Acoustalloy diaphragm in combination with an

exceptionally low-mass aluminum voice coil. Using this

diaphragm assembly, the RE20 is capable of reproducing

extremely high sound pressure levels with no fear of the

overload and distortion often experienced with phantom-

powered condensers. The RE20 will also continue to function

flawlessly in high humidity and elevated temperatures that

would seriously degrade competitive condenser microphones.

A massive steel housing and effective hum-bucking coil assure

the RE20’s resistance to magnetically induced hum and noise.

This means the RE20 can be used successfully in situations

where other microphones would experience unacceptable

levels of hum and buzz. By exploiting the strength of its steel

housing and employing a mechanical nesting concept, EV

designers have created an exceptionally rugged microphone

with superior handling noise rejection ideally suited for

professional uses.

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.

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.
