Audio Technica ES933C – Cardioid Condenser Hanging Microphone

Audio Technica ES933C

With durable construction and unobtrusive appearance, the Audio Technica 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 120 acceptance angle. 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.
