Description
The U853RU is a wide-range miniature condenser microphone with a UniLine (line 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 UniLine (line cardioid) polar pattern provides a 90° angle of acceptance. Additional interchangeable elements with omnidirectional (360°), cardioid (120°) and hypercardioid (100°) pickup patterns are available.
The microphone Includes a 7.6 m (25') permanently attached miniature cable. Its free end connects to the provided AT8538 power module via a special TA3F-type connector designed to optimize RFI immunity. The output of the power module is a 3-pin XLRM-type connector. A recessed switch in the power module permits 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 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 U853RWU.
