Perfect for speech, theater, orchestra and choir sound reinforcement and recording, the U853R cardioid condenser hanging microphone is equipped with UniGuard® innovations that offer unsurpassed immunity from radio frequency interference. With a consistent cardioid polar pattern, the mic offers natural sound from any angle, and superior gain before feedback. It is phantom powered and features an integral 80 Hz low-cut UniSteep® filter that reduces pickup of low-frequency ambient noise. The microphone accepts interchangeable elements, available in cardioid, hypercardioid, omnidirectional and UniLine® line cardioid polar patterns.
Designed for suspension over choirs, instrumental groups and theater stages
Superior off-axis rejection for maximum gain before feedback
UniGuard® RFI-shielding technology offers outstanding rejection of radio frequency interference (RFI)
UniSteep® filter provides a steep low-frequency attenuation to improve sound pickup without affecting voice quality
Accepts interchangeable elements to permit angle of acceptance from 90° to 360°
