The new Engineered Sound.
Contractor-exclusive innovations for every acoustical challenge. And
safe haven from RFI.
With durable construction and unobtrusive appearance, the ES933C
offers versatile solutions for speech, theater, 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 colors: 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.
- Designed for quality sound reinforcement, professional recording, television and other demanding sound pickup applications
- Small size and excellent response are ideal for suspension over choirs, instrumental groups and theater stages
- Low-profile element provides uniform cardioid polar pattern with 120º acceptance angle
- Available interchangeable elements permit angle of acceptance from 90º to 360º
- Superior off-axis rejection for maximum gain before feedback
- Requires 11V to 52V DC phantom power
- 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
- Available in two colors: black (ES933C) and white (ES933WC)
- RoHS compliant—free from all substances specified in the EU directive on hazardous substances
