Crown GLM100 Mini Microphone

More...

lavalier microphone, or hidden on a film set, the GLM disappears in use yet provides excellent sound quality. The omnidirectional GLM 100 is the best choice if you need less wind noise, less pickup of mechanical vibration, deep low frequency response down to 20 Hz, lots of volume up to 150 dB maximum SPL or smoother frequency response. Made of a rugged, resilient space age material, the GLMs molded housing is designed to resist damage from demanding professional use. Performance benefits of the GLM include a wide, smooth frequency response; excellent transient response; and minimal off axis coloration. The GLMs housing is designed to improve the high frequency response of the microphone capsule. In contrast, the frequency response of large microphone capsules often is degraded by the microphone housing due to sound diffraction. Included with the GLM 100 are a GLM UM Universal Mount, a GLM TB Tie Bar, GLM BC Belt Clip, and a GLM WS2 Windscreen. Specifications Type Miniature condenser. Element Electret condenser.
