Overview
Featuring Audio-Technica’s UniLine® line-cardioid element, the U853PMU condenser hanging microphone comes equipped with a wall/ceiling plate power module for permanent installation in a standard, single-gang electrical box. The phantom-powered microphone also offers UniGuard® innovations that deliver unsurpassed immunity from radio frequency interference. It 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.
