Overview

U857Q

Ideal for conference centers, boardrooms, courtrooms, houses of worship, and other installed applications, the U857Q is designed to plug directly into a panel- or desk-mounted XLRF-type connector. Offering unsurpassed immunity from radio frequency interference thanks to Audio-Technica’s UniGuard® innovations, this quick-mount microphone features an ultra-flexible, small-diameter gooseneck and accepts interchangeable elements – omnidirectional (360°), cardioid (120°), hypercardioid (100°), and UniLine® (90°) – available separately. Equipped with self-contained electronics, the phantom-powered microphone also offers an 80 Hz low-cut UniSteep® filter that reduces pickup of low-frequency ambient noise.

Available configurations:

U857Q: cardioid polar pattern (120° acceptance angle); 14.37" (365.0 mm) long.

U857QL: cardioid polar pattern (120° acceptance angle); 18.94" (481.0 mm) long.

U857QU: UniLine polar pattern (90° acceptance angle); 19.17" (487.0 mm) long.

U857QLU: UniLine polar pattern (90° acceptance angle); 23.74" (603.0 mm) long.
