DESCRIPTION AND APPLICATIONS
The Electro-Voice RE50 and
RE50/B
are
specially shock-isolated, omnidirectional,
dynamic microphones created for the most
exacting professional applications.
An advancement in shock-mounting techniques, they were designed particularly for
hand-held broadcast and sound reinforcement
use. All handling noises, clothing noises, and
even cord shock have been isolated from the
microphone element so that mechanical
induced noise is greatly reduced. By use of a
high-mass zinc internal acoustic chamber,
shock-mounted within the machined aluminum
outercasing, the
RE50
and
RE50/B
offer a
degree of isolation unprecedented in an
omnidirectional dynamic microphone.
The internal transducer uses a mechanical
nesting concept all its own. Each part is
nested inside another so that the transducer
(head assembly) is nearly a solid structure. It
is highly resistant to damage from shock. The
diaphragm is unaffected by temperature
extremes and atmospheric conditions. A
carefully designed integral windscreen and
blast filter provides excellent protection from
wind noise, excessive sibilance, and annoying
“p-popping”. The
RE50
and
RESO/B
have a
grille that bounces back to retain its shape. A
four-stage pop filter prevents dust and
magnetic particles from reaching the
diaphragm. The
RE50/B’s
attractive,
nonreflecting, semi-gloss black finish is ideal for
on-camera use.
ARCHITECTS’ AND ENGINEERS’
SPECIFICATIONS
The microphone shall be an omnidirectional,
dynamic type with broadcast range response
from 80 to 13,000 Hz. It shall employ a
highmass zinc acoustic chamber, integral with the
head assembly that shall be shock-isolated
within an external aluminum case. It shall
have a four-stage pop filter to prevent dust
and magnetic particles from reaching the
diaphragm. Nominal impedance shall be 150
ohms (such that it will match
50-, 150-,
and
250-ohm inputs). The line shall be balanced
to ground and phased.
Output level shall be -55
dB
with 0
dB
equalling 1
mW/pascal.
The magnetic circuit
shall be a non-welded circuit and employ
Alnico V and magnetic iron. The inner case
shall be made of zinc and the outer case of
machined aluminum.
The microphone shall have a maximum
diameter of 49 mm (1.94 in.) and
a length of
197 mm (7.75 in.). Shank diameter shall be
25 mm (1 .O in.). Weight shall be 269 grams
(9.5 oz.). Finish shall be semi-gloss black.
The microphone shall have
a
built-in
connector similar or equivalent to the
Switchcraft
A3M.
The Electro-Voice Model RE50 and
RE5O/B
are specified.

specific legal rights, and you may also have
other rights which vary from state to state.
Electro-Voice N/D, PL, BK, and Professional Microphones are guaranteed against
malfunction from any cause for two (2) years
from the date of original purchase. In addition,
the Limited Warranty for the acoustic system
contained in these microphones shall apply
for the life of the product, defined
as
a period
of ten (10) years from the date that the
manufacture of the specific microphone has
been discontinued. Any and all active
electronics incorporated in these microphones
are guaranteed against malfunction due to
defects in materials or workmanship for a
period of three (3) years from the date of
original purchase. The Limited Warranty does
not extend to cables, cable connectors, or
switches. Additional details are included in the
Uniform Limited Warranty statement.
