U857Q – Overview
Ideal for conference centers, boardrooms, courtrooms, houses of worship, and other installed applications, the Audio-Technica U857Q is designed to plug directly into a panel- or desk-mounted XLRF-type connector. This cardioid condenser quick-mount gooseneck microphone offers unsurpassed immunity from radio frequency interference thanks to Audio-Technica’s UniGuard® innovations. The 14.47″ long microphone features an ultra-flexible small-diameter gooseneck and accepts interchangeable elements, available in cardioid, hypercardioid, omnidirectional and UniLine® line cardioid polar patterns. Equipped with self-contained electronics, the phantom-powered microphone also offers an 80Hz low-cut UniSteep® filter that reduces pickup of low-frequency ambient noise.
