Electro-Voice RE38N Brochure & Specs

Description
The Electro-Voice Model RE38N/D is a pro-
fessional quality dynamic cardioid micro-
phone designed especially for recording,
broadcast and sound reinforcement applica-
tions requiring smooth tailorable response
over a wide frequency range. The extended
high frequency response and the 16-position
equalization switch give the RE38N/D great
flexibility in obtaining the appropriate sound
for any situation. For those applications that
require a deeper sound, the microphone has
bass-boosting "proximity effect" when used
up close. The amount of this "proximity ef-
fect" can be reduced by adjusting the equal-
ization switch as shown on the frequency
response curves. The "brightness" of the high
frequency response is also adjustable with
the equalization switch.
The RE38N/D incorporates a revolutionary
neodymium alloy magnet to provide high
sensitivity. Combined with the inherent low
noise of a dynamic transducer, the high sen-
sitivity ensures a superior signal-to-noise
ratio ready for digital recording and sam-
pling. To further reduce noise, the micro-
phone uses a humbucking coil to attenu-
ate from lighting and other sources. The
RE38N/D utilizes DynaDamp
vanced vibration-isolation material, so that
a large external shockmount is not required
for studio use. DynaDamp™ is a unique
foamed elastomer, specially formulated for
vibration control.
The dynamic element of the RE38N/D pro-
vides reliable operation in humidity and tem-
perature extremes. An Acoustifoam™ pop
filter reduces both wind noise and "P-pop"
breath sounds. The microphone features a
rugged machined aluminum case and
Memraflex™ grille screen designed to with-
stand all the rigors of professional use.
To solve the problem of microphone place-
ment the RE38N/D features a pivoting yoke
configuration. With the unique pivoting
yoke, the microphone can be easily adjusted
to position the front toward the sound source.
The yoke positions are detented to assure the
microphone doesn't shift during usage. This
adjustment option in combination with the
stand adapter provides a highly flexible
mounting system.
The cardioid polar pattern of the RE38N/D
provides excellent isolation at all frequen-
cies. The directional control is smooth in
transition from front to back to keep off-axis
coloration to a minimum.

Using the Equalization Adjustments
The graphic pictorials on the RE38N/D
nameplate provide an approximation of the
16 possible far-field (distant) frequency re-
sponses which may be selected. This flex-
ibility allows the user to obtain a desired
sound character in almost any situation right
at the microphone. There are eight low fre-
quency tailoring combinations and two high
frequency combinations to yield a total of
16 possible frequency responses built into
the RE38N/D. With these options, the user
can compensate for proximity effect, low fre-
quency noise and sibilance to get that "right
sound." The control is easy to adjust with a
small screwdriver (provided) yet cannot be
accidentally changed during use.
Experimentation is encouraged with the
equalization positions to get the perform-
ance best for your application. To aid in de-
termining the frequency response which is
right for your application, the typical re-
sponses for the positions are shown in Fig-
ures 1 through 16.
Switch position 1 yields the flattest fre-
quency response of all the positions to give

put sound for signals in the far field. The far
