U853AU UniLine® 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

Available in two colors: black (U853AU) and white (U853AWU)

Operates on battery or phantom power
