The BP893 is positioned unobtrusively over either ear. Its omnidirectional miniature condenser capsule offers outstanding pickup tailored for crystal-clear vocal reproduction, similar to that of a high-quality lavalier microphone. The mic is also ideal for use in violin pickup violinists should simply wear the BP893 over the ear as usual, and there is no need for clamps on the violin.

The microphone includes a 55-inch (1.4-meter) permanently attached miniature cable. Its free end connects to the provided AT8539 power module via a locking four-pin connector. The connector is also compatible with all A-T UniPak body-pack transmitters. The output of the power module is a three-pin XLRM-type connector.

The microphone requires 11V to 52V phantom power for operation. A recessed switch in the power module permits the choice of flat response or low-frequency roll-off (via the integral 80-Hz high-pass UniSteep filter) to help control undesired ambient noise. The BP893 comes equipped with a power module, a cable clip, two windscreens, two element covers, a moisture guard, a belt clip and a protective carrying case. The microphone is available in both black and theater beige.

The microphone is also available in a variety of wireless models, including the BP893cW.
