U859QL
Cardioid Condenser Quick-Mount Gooseneck Microphon

Designed to plug directly into a panel- or desk-mounted XLRF-type connector, the U859QL 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 80 Hz low-cut UniSteep® filter that reduces pickup of low-frequency ambient noise. The microphone is 18.90” long.
