Audio Technica ES943C Lavalier Microphone (ES943 C)
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.
- 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) permanently attached miniature cable connects to AT8538 power module via TA3F-type connector
- Requires 11V to 52V DC phantom power
- Superior off-axis rejection for maximum gain before feedback
- UniGuard® RFI-shielding technology offers outstanding rejection of radio frequency interference (RFI)
Integral UniSteep® filter provides a steep low-frequency attenuation to improve sound pickup without affecting voice quality
