Audio-Technica U857QLU UniLine Condenser Quick-Mount Gooseneck Microphone, Black

With advanced capsule design coupled with carefully engineered internal electronics, the U857QLU UniLine condenser delivers clear, consistent sound for a variety of installed applications. The 23.74" version of U857QU, the U857QLU features Audio-Technica’s UniLine line-cardioid element. The microphone is designed to plug directly into a panel- or desk-mounted XLRF-type connector. Its ultra-flexible, robust gooseneck permits easy adjustment into desired shape while resisting inadvertent repositioning. Featuring UniGuard innovations that offer unsurpassed immunity from radio frequency interference, the U857QLU accepts new interchangeable elements, available in cardioid, hypercardioid, omnidirectional and UniLine line cardioid polar patterns. The phantom-powered microphone also offers an 80 Hz low-cut UniSteep filter that reduces pickup of low-frequency ambient noise.
