The AT829cW is a wireless clip-on/lavalier condenser microphone with a cardioid polar pattern. It is designed for professional business presentations, public speaking and theater performances. The microphone is intended to be worn on the clothing for excellent yet unobtrusive sound pickup. The wide-range capability of the microphone ensures clean, accurate reproduction with high intelligibility for speakers, presenters and other performers. The microphone's cardioid polar pattern provides a 120° angle of acceptance. The microphone includes a 1.4 m (55") permanently attached miniature cable. Its free end terminates in a locking 4-pin connector for use with Audio-Technica UniPak® body-pack transmitters. The microphone comes equipped with a clothing clip and a windscreen. Operation For use as a lavalier, attach the microphone about six inches below the chin. Anticipate movements that may cause the microphone to rub against or be covered by clothing, and position the microphone to avoid it. The provided foam windscreen simply slips over the head of the microphone, effectively reducing wind noise and popping. Avoid leaving the microphone in the open sun or in areas where temperatures exceed 110° F (43° C) for extended periods. Extremely high humidity should also be avoided.
