MicroSet® Cardioid Condenser Headworn Microphones
Features
BP894 Description
The BP894 is a headworn condenser microphone with an cardioid polar pattern. It is
designed to provide intelligible natural audio for stage and television talent, lecturers
and houses of worship.
The microphone requires 11V to 52V phantom power for operation.
The microphone includes a 1.4 m permanently attached miniature cable. Its free end
connects to the provided AT8539 power module via a locking 4-pin connector. The
connector is also compatible with all Audio-Technica UniPak® body-pack transmitters.
The output of the power module is a 3-pin XLRM-type connector.
A recessed switch in the power module permits choice of flat response or low-
frequency roll-off (via integral 80 Hz high-pass UniSteep® filter) to help control
undesired ambient noise.
The microphone comes equipped with a power module, a cable clip, a dual-ear mount,
two windscreens, two element covers, a moisture guard and a protective carrying
case. The microphone is available in black and beige.
Wireless MicroSet® Description
The microphone is also available in a variety of wireless models, including the
BP894cW. The BP894cW includes a 1.4 m permanently attached miniature cable
terminated with a locking 4-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 BP894.
Avoid leaving the microphone in the open sun or in areas where temperatures exceed
43° C for extended periods. Extremely high humidity should also be avoided.
