Cardioid Condenser Hanging Microphone
Share

Details

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
