Electro-Voice 635nd-b eds User Manual

The Electro-Voice 635N/D and 635N/D-B

dynamic omnidirectional microphones are

offspring of the legendary 635A microphone.

Built with the same rugged design of the

635A, the 635N/D and 635N/D-B offer a

new neodymium N/DYM

®

 magnet structure

for greater sensitivity. Designed for increased

ruggedness to meet the demands of exacting

professional applications, the 635N/D’s and

635N/D-B’s are ideally suited for electronic

news production (ENG), electronic field pro-

duction (EFP), television, film and radio

remotes and demanding PA applications.

The microphone’s Acoustalloy

®

 diaphragm

permits a very smooth response over a wide

frequency range, yet it withstands high hu-

midity and temperature extremes, corrosive

effects of salt air and severe mechanical

shocks. The diaphragm is protected from dust

and magnetic particles by a carefully de-

signed integral windscreen and blast filter.

The windscreen provides excellent protec-

tion from wind noise, excessive sibilance and

annoying “P-popping.” This helps minimize

the need for an external windscreen for out-

door use.

The 635N/D comes in nonreflecting fawn

beige; the 635N/D-B comes in semigloss

black for “on camera” use. The increased

output level and low sensitivity to mechani-

cal shock make the 635N/D and 635N/D-B

excellent for interviews, sporting events,

special effects and voice-overs.

Both microphones come with the 311 stand

adapter.

The microphone shall be an omnidirectional

dynamic type with wide-range response uni-

form from 80 to 13,000 Hz. It shall have a

nonmetallic diaphragm and an internal pop

filter and magnetic shield to prevent dust and

magnetic particles from reaching the dia-

phragm. The impedance 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 microphone shall have a maximum di-

ameter of 36 mm (1.42 in.), a length of

148 mm (5.84 in.) and a weight of  170 g (6 oz).

Finish shall be nonreflecting fawn beige

(635N/D) or semigloss black (635N/D-B).

The microphone shall have a built-in

XLR-type connector, and shall include a

5

/8-in.-27-thread stand coupler.
