General Description:

The Electro-Voice® 635A and 635A/B are designed
for exacting professional applications such as film
production, recording, broadcasting, and the more
demanding PA applications. The 635A and 635A/B may
be purchased in packages of six. These “six packs”
do not include the stand adapter. The high output level,
and low sensitivity to mechanical shock, make the 635A
and 635A/B excellent for interviews and for pass-around
use in audiences. The 635A and 635A/B feature a
diaphragm which permits very smooth response over
a wide frequency range. The diaphragm withstands
humidity and temperature extremes, corrosive effects
of salt air, and severe mechanical shocks. It is
practically indestructible with normal use. A four-stage
pop and dust filter ensures a completely pop-free
performance and virtually eliminates the need for an
external windscreen during outdoor use. An internal
shock absorber effectively reduces the pickup of cable
and other noise generated by external contact.

Architects’ and Engineers’ Specifications:

The microphone shall be an Electro-Voice 635A or 635A/B. The microphone shall be an omnidirectional dynamic type with
wide range response uniform from 80-13,000 Hz. It shall have a four-stage pop filter, and magnetic shield to prevent dust
and magnetic particles from reaching the diaphragm. 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 -55 dB with 0 dB
equaling 1.4mV/pascal. The magnetic circuit shall be a nonwelded circuit and employ Alnico V and magnetic iron. The
case shall be made of steel. The microphone shall have a maximum diameter of 36 mm (1.41 in.), a length of 151 mm (5.94
in.) and a weight of 170 grams (6 oz.) The Electro-V oice 635A and 635A/B are specified.
