The U853PM is a wide-range miniature condenser microphone with a cardioid polar pattern. It is designed for quality sound reinforcement, professional recording, television and other demanding sound pickup applications. The combination of small size and excellent response makes the microphone ideal for suspension over choirs, instrumental groups or theater stages.
The microphone requires 11V to 52V phantom power for operation. The microphone is equipped with UniGuard RFI-shielding technology, which offers outstanding rejection of radio frequency interference (RFI). The microphone's cardioid polar pattern provides a 120° angle of acceptance. Additional interchangeable elements with omnidirectional (360°), hypercardioid (100°) and UniLine (90°) pickup patterns are available.
The microphone includes a 7.6 m (25') permanently attached miniature cable. Its free end connects to the provided AT8534 wall/ceiling plate power module via a special TA3F-type connector designed to optimize RFI immunity. The power module features a white-finished standard electrical cover plate for easy, secure installation. Output connections on the power module are screw terminals.
Switches in the power module permit a +10 dB gain setting for extra sensitive pickup as well as a choice of flat response or low-frequency roll-off (via integral 80 Hz high-pass UniSteep filter) to help control undesired ambient noise. The microphone comes equipped with a wall/ceiling plate power module, a vinyl-coated steel hanger for positioning over a choir/orchestra/stage, a two-stage foam windscreen, and a 5/8"-27 stand adapter. The microphone is enclosed in a rugged housing with a low-reflectance Black finish. It is also available with White housing, cable, hanger and windscreen as the U853PMW.
