The U853R cardioid condenser hanging microphone is ideal for speech, theater, orchestra and choir sound reinforcement and recording. The battery- or phantom-powered microphone is equipped with UniGuard RFI-shielding innovations and a UniSteep® filter. Includes foam windscreen and stand adapter .

The microphone's fast transient response and low distortion characteristics allow every complex detail to be heard with all its impact—rich, vibrant qualities faithfully reproduced. Equipped with UniGuard™ innovations that offer unsurpassed immunity from radio frequency interference, the U853A accepts interchangeable elements, available in cardioid, hypercardioid, omnidirectional and UniLine™ line cardioid polar patterns. The battery- or phantom-powered microphone also offers an 80 Hz low-cut UniSteep® filter that reduces pickup of low-frequency ambient noise.
