BP898 Subminiature Cardioid Condenser

Lavalier Microphone

Broadcast & Production

Features

• Maximum intelligibility and clean, accurate reproduction for vocalists,

lecturers, stage and television talent, and worship leaders

• Cardioid capsule provides directional pickup with pronounced proximity eect

at close range that enhances the user’s voice

• Low-proﬁle design (a mere 5.3 mm in diameter) is ideal for applications

requiring minimum visibility

• Urethane elastomer cable with a double-spiral shield wire provides ultimate

ﬂexibility, strength, and resistance to abrasion and moisture

• RoHS compliant – free from all substances speciﬁed in the EU directive on

hazardous substances

• The microphone capsule is housed in a rugged metal structure to shield the

electronic circuitry from external electromagnetic noise

• The signal line of the cable is made of a high-durability CuSn (copper and tin)

alloy that greatly enhances corrosion resistance and increases longevity

• Two included windscreens each feature a plastic structure that keeps the

windscreen secured to the microphone

• Clothing clip includes 16 distinct angle adjustments over 360° and two strain-

relief clips for easy cable routing

• Also available in wireless models (without power module) terminated for

use with Audio-Technica wireless systems and many other manufacturers’

wireless systems

Wired Description

The BP898 is a subminiature clip-on/lavalier condenser microphone with a cardioid

polar pattern. It is designed to provide accurate reproduction for lecturers, stage and

television talent, and houses of worship.

The microphone is intended to be worn on clothing or hidden in props for excellent

yet unobtrusive sound pickup. The wide-range capability of the microphone ensures

clean, accurate reproduction with high intelligibility for speakers, presenters and

other performers. Its small size makes it ideal for use in applications where minimum

visibility is required.

The microphone requires 11V to 52V phantom power.

The microphone’s cardioid polar pattern provides a 120° angle of acceptance.

The microphone includes a permanently attached 1.4 m (55") long, 2.0 mm (0.08")

diameter, 2-conductor shielded cable. Its free end connects to the provided AT8545

power module via a cH connector. 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-o (via integral 80 Hz high-pass ﬁlter) to help control undesired

ambient noise.

The microphone comes equipped with a power module, a clothing clip, and two

windscreens. A protective carrying case is also included. The microphone has a low-

reﬂectance black ﬁnish.

Operation and Maintenance

The BP898 requires 11V to 52V phantom power.

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 ﬁlter provides easy switching from a ﬂat frequency

response to a low-end roll-o. The roll-o position reduces the microphone’s sensitivity

to popping in close vocal use. It also reduces the pickup of low-frequency ambient

noise (such as trac, air-handling systems, etc.), room reverberation and mechanically

coupled vibrations. To engage the high-pass ﬁlter, use the end tip of a paperclip or other

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

The directionality of the BP898 cardioid element has a pronounced proximity

eect when used at close range, enhancing the user’s voice. This low-frequency

enhancement drops o when the microphone is used at a distance. If the mic needs

to be used at a greater distance or a less focused pickup is desired, the BP899 with

an omnidirectional capsule is recommended.

When using the microphone in extremely close situations, slip the included open-

pore foam windscreen over the mic to reduce wind noise or popping.

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.

Wireless Models Description

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

BP898cH. The BP898cH includes a 1.4 m (55") permanently attached miniature cable

terminated with a screw-down 4-pin connector for use with Audio-Technica cH-style

body-pack transmitters. Models are also available in a variety of terminations for use

with many other manufacturers’ wireless systems. No power module is included (or

required) with the wireless models. The wireless models’ dimensions, polar pattern

and included accessories are otherwise identical to those of the BP898.

Also available unterminated as the BP898c.
