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 and U857QLU features Audio-Technica 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.
