BP892 Description

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 at response or low-frequency roll-off (via integral 80 Hz high-pass UniSteep

lter) 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.

Wireless MicroSet

Description

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.

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

lter provides easy switching from a at 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 trafc, air-handling systems, etc.), room reverberation and mechanically coupled vibrations. To engage the UniSteep

lter, use the end tip of a paperclip or other small

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

The exible 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 t, 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 ts 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 t 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 t of the headband as needed, by sliding the headband’s adjusting tabs until you arrive at a secure, comfortable t (a). Attach the microphone cable to the cable clip positioned between the headband’s adjusting tabs (b).

The BP892cW is also available unterminated as the BP892c.

Roll-off

The donut-shaped moisture guard is provided to protect the element from sweat and moisture. Position the moisture guard as close to the element as possible to provide maximum protection. To remove the moisture guard, rst remove the element cover and place it out of harm’s way. Gently slide the moisture guard over the element. Replace the element cover.

Avoid leaving the microphone in the open sun or in areas where temperatures exceed 110° F (43° C) for extended periods. Extremely high humidity should also be avoided.
