    Required Accessories

    The Audio Technica U853AU 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 or a 1.5V AA battery for operation. A battery need not be in place for phantom power 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 AT8531 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 3 position switch in the power module permits choice of off, on/flat response, or on/low-roll-off (via integral 80 Hz high-pass UniSteep filter). The roll-off position reduces the pickup of low-frequency 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, a 5/8"-27 stand adapter and a battery. 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 U853AWU.
