With durable construction and unobtrusive appearance, the ES933C offers versatile solutions for speech, theatre, orchestra and choir sound reinforcement and recording. The microphone's low-profile element provides a uniform cardioid polar pattern with 120º acceptance angle. Available in two colours: black (ES933C); white (ES933WC), the microphone offers unsurpassed immunity from radio frequency interference thanks to UniGuard® innovations. The ES933C also offers an 80 Hz low-cut UniSteep® filter that reduces pickup of low-frequency ambient noise.
