Audio-Technica BP894x
BP894xAudio-Technica’s innovative BP894x MicroSet® in black offers the ultimate in low-profile, high-performance audio.
This ultra-lightweight microphone hooks securely behind either ear and features a rotating capsule housing with talk-side indicator for perfect polar pattern placement. With its capacity for aiming the cardioid condenser capsule directly at the sound source, the microphone provides excellent rejection of outside noise, with exceptional gain-before-feedback when used with live sound systems and stage monitors.
The BP894 MicroSet’s subminiature cardioid condenser capsule delivers extremely intelligible, natural audio with a flat, extended frequency response that is ideal for stage and television talent, lecturers, and worship leaders. Engineered to stand up to the rigors of day-to-day use, the BP894x includes a detachable, field-replaceable cable with a robust connector at the earset and a variety of available output terminations.
