(Dave Molter | Posted 2010-11-19)
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
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.
