Audio-Technica U853AU Cardioid Condenser Hanging Microphone
Equipped with Audio-Technica's UniLine® line-cardioid element with a tightly focused 90º acceptance angle, the U853AU features UniGuard® innovations that offer unsurpassed immunity from radio frequency interference. The battery- or phantom-powered microphone accepts interchangeable elements, available in cardioid, hypercardioid, omnidirectional and UniLine® line cardioid polar patterns. It also offers an 80 Hz low-cut UniSteep® filter that reduces pickup of low-frequency ambient noise.
Designed for suspension over choirs, instrumental groups and theater stages
UniLine polar pattern provides narrow 90° acceptance angle
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°
Low-profile design with low-reflectance finish for minimum visibility
