Omnidirectional Condenser Microphone

The ES943/O omnidirectional condenser lavalier is intended to be worn on the clothing for excellent, unobtrusive sound pickup. The microphone’s wide-range capability ensures clean, accurate reproduction with high intelligibility for speakers, singers and other performers. Its low-profile element with 360º acceptance angle provides full audio coverage and reduced susceptibility to clothing and cable noise. A recessed switch in the power module permits choice of flat response or low-frequency roll-off to help control undesired ambient noise.

  • Designed for quality sound reinforcement, professional recording, television and other demanding sound pickup applications
  • Small size and excellent response provide crisp, full-sounding voice pickup
  • Available interchangeable elements permit angle of acceptance from 100º to 360º
  • 55” (1.4 m) cable permanently attached to mic, screw terminals at power module
  • Also available as: ES943cW/O — less power module; 55” (1.4 m) cable terminated with locking 4-pin connector for A-T UniPak™ wireless systems
