Overview
The new Engineered Sound. Contractor-exclusive innovations for every acoustical challenge. And safe haven from RFI.
With durable construction and unobtrusive appearance, the ES933WML offers versatile solutions for speech, theater, orchestra and choir sound reinforcement and recording. The microphone's low-profile element provides a uniform MicoLine polar pattern with narrow 90º acceptance angle. Available in two colors: black (ES933ML); white (ES933WML), the microphone offers unsurpassed immunity from radio frequency interference thanks to UniGuard® innovations. The ES933WML also offers an 80 Hz low-cut UniSteep® filter that reduces pickup of low-frequency ambient noise.
Features
