BP893 Description

The BP893 is a headworn condenser microphone with an omnidirectional

polar pattern. It is designed to provide clear, natural vocal pickup in theatrical

performances, houses of worship and broadcast studios.

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.

The BP893 MicroEarset is positioned unobtrusively over the ear. Its

omnidirectional miniature condenser capsule offers outstanding pickup

tailored for natural vocal reproduction, with audio reproduction similar to

that of a high-quality lavalier microphone. The microphone is also ideal for

use in violin pickup; wear the BP893 over the ear as usual, with no need for

clamps on the violin.

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, 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 Description

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

the BP893cW. The BP893cW 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 BP893.

The BP893cW is also available unterminated as the BP893c.

Operation and Maintenance

The BP893 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

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 BP893 can be worn on either the left or right ear. Position the ear loop

around the back of your ear, so that the boom extends from the top of your

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

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 MicroEarset side of the clip

to allow for free, comfortable motion.

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.

Architect’s and Engineer’s Specications

The microphone shall be a xed-charge condenser designed for headworn

use. It shall have an omnidirectional polar pattern and a frequency response

of 20 Hz to 20,000 Hz. The microphone shall operate from an external 11V

to 52V DC phantom power source. It shall be capable of handling sound

input levels up to 114 dB with a dynamic range of 88 dB. Nominal open-

circuit output voltage shall be 19.9 mV at 1V, 1 Pascal. Output shall be low

impedance balanced (245 ohms).

The microphone shall have a 1.4 m (55") permanently attached miniature

cable terminating in a locking 4-pin output connector. The output connector

shall connect to a jack on the included power module. The output connector

shall also connect to any Audio-Technica UniPak

body-pack wireless

transmitter. The power module shall contain a recessed switch to permit

choice of at response or 80 Hz low-frequency roll-off. The output of the

power module shall be a 3-pin XLRM-type connector.
