Microphone
The microphone is a noise-cancelling dynamic microphone designed for close-talking, hand-held
applications in quality sound installations where background noise is a problem. The frequency
response, especially tailored for voice communications, provides a crisp, clear, highly intelligible sound
with 360 degrees minimization of background noise. A soft lip guard is positioned to assure proper close
talk voice spacing by the operator. It offers extreme reliability, convenient handling, rugged construction
and high performance for years of dependable service. The dynamic cartridge has a rugged polyester
diaphragm which resists moisture, temperature extremes, most acids, alkalis and solvents. Molded in
high impact Cycolac, it comes with a permanently attached, heavy duty, four-conductor, two shielded,
coil cord and a simple to operate DPDT long life, trouble free switch. It has a low-impedance output and
is factory wired normally open.
