The new Engineered Sound. Contractor-exclusive innovations for every acoustical challenge. And safe haven from RFI. The ES943C 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 provides a uniform cardioid polar pattern with 120º 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 Audio-Technica’s UniGuard® innovations.
