Details
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.
