Product Description
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 80Hz 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° : UE-C cardioid (120°); UE-H hypercardioid (100°); UE-O omnidirectional (360°)
- Low-profile design with low-reflectance finish for minimum visibility
- Hanging Choir Microphone
- Available in two colors: black (U853AU) and white (U853AWU)
- Operates on battery or phantom power
