Audio-Technica AT803 Omnidirectional Condenser Lavalier Microphone

Worn on clothing or hidden in props, the Audio-Technica AT803 is an omnidirectional condenser lavalier that gives lecturers and stage and TV performers unobtrusive sound pickup.

Its small size keeps it out of sight, and it also works as a clip-on instrument mic. The 1.8 m (6 ft) cable is permanently attached and plugs into the AT8531 power module through a TA3F-type connector, and the module provides a 3-pin XLR output.

A three-position switch on the module turns the mic off, on with a flat response, or on with an 80 Hz low-frequency roll-off. The roll-off reduces low-frequency ambient noise, room reverberation, mechanically coupled vibration, and popping in close vocal use.

The AT803 runs on 11 to 52 V phantom power or one AA battery in the power module. The battery is not included. Wear it about six inches below the chin, where clothing will not rub against it.
