UniLine® Condenser Hanging Microphone


The white version of U853RU, the U853RWU UniLine condenser hanging microphone features Audio-Technica’s UniLine® line-cardioid element and 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.
