Electro-voice 635A/B (Classic dynamic omnidirectional interview microphone, black)

Description

General Description:
Key Features:
• Practically indestructible in normal use
• Steel housing provides magnetic shielding
and strength
• Withstands humidity, salt air, and severe
mechanical shocks
• Self generating, no powering required
• Uniform 80-13,000 Hz response
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 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.
