 Omnidirectional Condenser Headworn Microphones

The BP892 is a headworn condenser microphone with an omnidirectional 

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 (55") 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, a 

belt clip and a protective carrying case. The microphone is available in black 

and beige.

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

the BP892cW. The BP892cW includes a 1.4 m (55") 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 BP892.

The BP892cW is also available unterminated as the BP892c.

The BP892 requires 11V to 52V phantom power for operation.

Output is low impedance (Lo-Z) balanced. The signal appears across Pins 

2 and 3; Pin 1 is ground (shield). Output phase is “Pin 2 hot”— positive 

acoustic pressure produces positive voltage at Pin 2. 

An integral 80 Hz high-pass UniSteep

®

 filter provides easy switching from 

a flat frequency response to a low-end roll-off. The roll-off position reduces 

the microphone’s sensitivity to popping in close vocal use. It also reduces 

the pickup of low-frequency ambient noise (such as traffic, air-handling 

systems, etc.), room reverberation and mechanically coupled vibrations. To 

engage the UniSteep

®

 filter, use the end tip of a paperclip or other small 

pointed instrument to slide the switch toward the “bent” line. 

The flexible design of the BP892 MicroSet enables it to be worn on either 

the left or right ear. Position the lightweight contoured loop around the 

back of your ear, so that the boom extends from the bottom of your ear. 

Bend the loop as needed to achieve a secure, comfortable fit, so that the 

MicroSet is not dislodged by shaking your head. Remove the MicroSet and 

bend a gentle curve in the microphone's boom. Hook the MicroSet back 

around your ear, and adjust the boom as needed to follow the contour of 

your face, positioning the microphone near the corner of your mouth. The 

microphone has a large acoustical sweet spot; experiment with placement 

near the corner of your mouth for optimal performance.

A cable clip is provided for strain relief, allowing the microphone to remain 

securely in place without the weight of the cable pulling on the headset. To 

install the cable clip, slip the cable into the snap-on connector and attach 

the clip to clothing, leaving enough slack on the MicroSet side of the clip to 

allow for free, comfortable motion.

The included AT8464 Dual-Ear Microphone Mount allows you to convert 

your single ear-worn BP892 MicroSet

®

 to a dual-ear-worn unit. The 

BP892 fits on either side of the Dual-Ear Microphone Mount, allowing 

the microphone to be worn to either the left or right of your mouth. The 

headband easily adjusts to fit both children and adults.

 

How to use the Dual-Ear Microphone Mount

1.  Insert the rounded end of your BP892 ear hook into the larger  

  opening of your Dual-Ear Microphone Mount’s left or right tapered 

  holder. Firmly seat ear hook in the tapered holder.

2. Insert the small rounded end of the additional supplied ear hook  

  into the larger opening of your Dual-Ear Microphone Mount’s  

  remaining tapered holder. Firmly seat ear hook in the tapered holder.

3. Open the Dual-Ear Microphone Mount’s adjustable behind-the-neck  

  headband to its maximum position by pushing the headband’s  

  adjusting tabs together (a). Put the behind-the-neck headband on, 

  hooking the ear hooks over your ears. Adjust the fit of the headband  

  as needed, by sliding the headband’s adjusting tabs until you arrive at  

  a secure, comfortable fit (a). Attach the microphone cable to the  

  cable clip positioned between the headband’s adjusting tabs (b).
