The AT899 subminiature omnidirectional microphone is engineered for intelligible, accurate voice reproduction. Its low-profile design (a mere 5 mm in diameter) assures minimum visibility. The mic may be worn as a lavalier and is easily hidden in clothing or hair. Includes a clothing clip, viper clip, magnet clip and lanyard, two windscreens, two element covers, three single mic holders, and two double mic holders.
Available configurations:
AT899: 9.8' (3.0 m) permanently attached cable terminated with TA3F connector; AT8537 power module (with 80 Hz high-pass filter) for battery or phantom power.
