The Astatic Noise-Canceling microphone is designed for close talking, handheld applications in quality sound installations where background noise is a problem. The omnidirectional dynamic microphone's frequency response, especially tailored for voice communications, provides a crisp, clear, highly intelligible sound with 360 minimization of background noise. A soft lip-guard is positioned to assure proper close-talk voice spacing by the microphone's operator. The dynamic cartridge has a rugged polyester diaphragm that resists moisture, temperature extremes, most acids, alkalines, and solvents. Molded in high-impact Cycolac, the 631L microphone comes with a permanently attached, heavy-duty, four-conductor, two-shielded coil cord. The low impedance Astatic Noise-Canceling Microphone is simple to operate. A trouble-free DPDT long-life switch is factory-wired normally open.
