Audio-Technica UniLine U853AU Cardioid Condenser Hanging Microphone

Equipped with Audio-Technica's UniLine™ line-cardioid element with a tightly focused 90° 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.

Features:

• 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
