The Audio Technica AT899CWTH is a sub-miniature condenser lavalier microphone designed to deliver high sonic performance in a low-profile, easily concealable package. Intended for interviews, documentary, film, theater, and stage applications, the AT 899's omni-directional pick-up pattern captures evenly around the perimeter of the capsule as well as directly in-line. The microphone's 5mm size is ideal in applications requiring minimal visibility, and its 55" (1.4 m) cable is terminated with a Locking 4-pin connector intended for direct use with Audio-Technica UniPak . The capsule features a smooth flat 20 to 20,000Hz frequency response, capturing a wide range of frequencies and making the microphone versatile.
