Featuring Audio-Technica’s UniLine® line cardioid element, the U853RU UniLine condenser hanging microphone is equipped with UniGuard® innovations that offer unsurpassed immunity from radio frequency interference. The phantom-powered microphone accepts interchangeable elements, available in cardioid, hypercardioid, omnidirectional and UniLine™ line-cardioid polar patterns. Its 80 Hz low-cut UniSteep® filter reduces pickup of low-frequency ambient noise.
