MicroLine® Condenser Gooseneck Microphone


The new Engineered Sound. Contractor-exclusive innovations for every acoustical challenge. And safe haven from RFI. This super-compact, small-diameter gooseneck delivers flexible positioning with a sleek, low-profile appearance. The mic’s low-profile element provides a uniform MicroLine polar pattern with narrow 90º acceptance angle. It is equipped with an 80 Hz low-cut UniSteep® filter that reduces pickup of low-frequency ambient noise. The microphone offers unsurpassed immunity from radio frequency interference thanks to UniGuard® innovations.


  • Designed for quality sound reinforcement, professional recording, television and other demanding sound pickup applications
  • Low-profile element provides uniform MicroLine polar pattern with narrow 90º acceptance angle
  • Unobtrusive design with an overall length of only 12
  • 45" (316
