Description

The U853A 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. U853AW is white version. Includes AT8531 power module with on/off/roll-off switch and XLR-style output connector. Also includes foam windscreen, stand adapter and battery.

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.
