Crown GLM100 Miniature Omnidirectional Condenser Microphone
The GLM-100 is an omnidirectional mic with a low impedance balanced XLR-type output, powered by 12 to 48V phantom power. It offers the quality of large studio microphones, yet is nearly invisible in use.
The GLM can be attached to an acoustic guitar, sax, flute or the performer's face to allow freedom of movement. It can be attached to drum rims to pick up a drum set without the unsightly clutter of boom stands. These attachments can be made using the included mounting hardware or tape. Used as a 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 GLM’s 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 GLM’s 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.
