This omnidirectional mic is very popular and highly recommended by our Engineers and Project Managers for high quality sound and speech reproduction. One of the most discreet mics on the market.
The AT803 provides excellent yet unobtrusive sound pickup for lecturers, stage/TV performers and houses of worship . Designed for clip-on lavalier and musical instrument use, it features an integral 80 Hz high-pass filter that provides easy switching from a flat frequency response to a low-end roll-off. The microphone operates on battery or phantom power.
