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.
