Audio-Technica unveils BP893 Headworn MicroEarset Microphone

Audio-Technica unveils its BP893 MicroEarset Omnidirectional Condenser Headworn Microphone. With its ergonomically molded earpiece and unobtrusive one-inch boom, the BP893 offers inconspicuous placement along with clear, consistent voice pickup. Its extended frequency response provides natural sound reproduction, and its lightweight low-profile design and ease of use make the microphone ideal for use in theatrical performances, houses of worship and broadcast studios.

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. The BP893cW includes a 55-inch (1.4-meter) permanently attached miniature cable terminated with a locking four-pin connector for use with Audio-Technica UniPak body-pack transmitters. Models are also available in a variety of terminations for use with many other manufacturers wireless systems (see below). No power module or belt clip is included (or required) with the wireless models. The wireless models dimensions, polar pattern and included accessories are otherwise identical to those of the BP893.

Audio-Technicas BP893 and BP893-TH will be available in December 2010 at an MSRP of $479.00.
