BP894

THE LATEST IN DISCRETION AND PERFORMANCE AUDIO

Audio-Technica’s innovative BP894 MicroSet® offers the ultimate in low-profile, high-performance audio. The BP894 features a rotating capsule housing with talk-side indicator for use on either ear and perfect polar pattern placement. The MicroSet BP894 takes headworn microphones to the next level, by allowing the cardioid capsule to be aimed directly at the sound source. The uniform pickup pattern provides excellent rejection of outside noise, with exceptional gain-before-feedback when used with live sound systems and stage monitors. Delivering clear and accurate sound in an inconspicuous package, the ultra-lightweight BP894 hooks securely behind either ear and can be worn for hours witout fatigue. For maximum stability and comfort, the included AT8464 dual-ear microphone mount converts the MicroSet to a dual-ear-worn unit.

“VERY LIGHTWEIGHT AND DISCREET”

With its ultra light weight of 2g and a capsule diameter of 2.8 mm, the BP894 headworn microphone is one of the lightest and discreet audio professional market.

“DUAL EAR CONTROL”

The AT8464 Dual-Ear Microphone Mount allows you to convert the BP894 from a single ear-worn MicroSet to a dual-ear worn unit for maximum stability and comfort. The microphone can be worn to the left or right. The headband is adjustable and suitable for both adults and children.

“SWIVEL CAPSULE”

Unique in its genre, The BP894 has a swiveling capsule of Ø2.8mm, providing direct aim at the mouth of the user, for unmatched intelligibility. The cardioid directivity guarantees better protection against feedback and reduces unwanted ambient noise (be it from stage monitor or front speakers). The capsule also allows the BP894 to pivot enabling wear on either ear. Simply adjust the support as desired for comfortable wearing, and orient the capsule towards the mouth. A small dot marks the active side of the capsule.
