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 tech-
niques, 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, non-
reflecting, 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 high-
mass 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.
