The Electro-Voice RE50N/D and RE50N/D-B

shock-mounted, dynamic omnidirectional

microphones are offspring of the legendary RE50

microphone. Built with the same rugged de-

sign as the RE50, the RE50N/D and RE50N/

D-B feature a DynaDamp

TM

 shock mount for

greater ruggedness and isolation, and a new

neodymium N/DYM

®

 magnet structure to

provide increased sensitivity required in ex-

acting professional applications.

Ideally suited for handheld broadcast and

sound reinforcement applications, the

RE50N/D and RE50N/D-B have been built

for superior isolation from mechanically in-

duced noise. Handling noise, clothing noise,

and even cord shock are isolated from the

microphone element. Within the

microphone’s machined-aluminum

outercasing, a DynaDamp

TM

 shock mount

(manufactured using an advanced vibration-

isolation material) surrounds the high-mass

internal acoustic chamber and microphone

element, resulting in a degree of isolation un-

precedented in an omnidirectional dynamic

microphone.

The transducer is protected through a unique

interlocking concept, making the RE50N/D

and RE50N/D-B practically indestructible

with normal use. The transducer, fitted within

a high-mass internal case, is shock-isolated

within an attractive external case, therefore

protecting the transducer from sudden shock.

The microphone’s diaphragm permits a very

smooth response over a wide frequency

range, yet it withstands high humidity and

temperature extremes, corrosive effects of

salt air and severe mechanical shocks. The

diaphragm is protected from dust and mag-

netic particles by a carefully designed inte-

gral windscreen and blast filter which also

provides excellent protection from wind

noise, excessive sibilance and annoying “P-

popping.” The microphone’s Memraflex

TM

grille is designed to bounce back to its origi-

nal shape when bumped or dropped.

The RE50N/D in nonreflecting fawn beige

or the RE50N/D-B in “camera” black are

ideal for “on-camera” use. Both microphones

are supplied with the 323S (black) stand

adapter and a zippered, vinyl carrying pouch.

The microphone shall be a shock-mounted,

omnidirectional, dynamic type with wide-

range response uniform from 80 to 13,000 Hz.

The microphone shall employ a high-mass

acoustic chamber, integral with the trans-

ducer assembly that shall be shock-isolated

within an external aluminum case. The mi-

crophone shall have an internal pop blast fil-

ter to prevent dust and magnetic particles

from reaching the diaphragm. The imped-

ance shall be such that the microphone will

match 50-, 150- and 250-ohm inputs. The

line shall be balanced to ground and phased.

The output level shall be –51 dB with 0 dB

equalling 1 mW/10 dynes/cm

2

. The magnetic

circuit shall be nonwelded  and employ a

neodymium alloy magnet. The inner case

shall be made of steel and the outer case of

machined aluminum.

The microphone shall have a maximum di-

ameter of 49 mm (1.94 in.) and a length of

197 mm (7.75 in.). Shank diameter shall

be 25 mm (1.0 in.). Weight shall be 269 g

(9.5 oz). Finish shall be nonreflecting

fawn beige micromatte (RE50N/D) or semi-

gloss black (RE50N/D-B). The microphone

shall have a built-in, 3-pin, XLR-type con-

nector, and shall include a

pouch.

The Electro-Voice RE50N/D and RE50N/D-B

are specified.
