Audio-Technica U891RWb Cardioid Boundary Microphone with LED and Local Switch (White)

Achieve clear, intelligible speech reproduction and easy local switching with the white Audio-Technica U891RWb, a cardioid condenser boundary microphone optimized for surface-mount applications in conference rooms, houses of worship, recording studios, live event venues, and sports arenas. The local touch-sensitive switch offers three modes for customizable control of talk/mute functions, and the microphone's on/off status is indicated by a two-state RGB LED. The high-output condenser element yields a wide frequency response of 20 Hz to 20 kHz, which can be modified via the switchable 80 Hz low-cut filter—ideal for mitigating rumble and low-frequency buildup.

The cardioid polar pattern delivers directional pickup and enhanced off-axis rejection, allowing reduced ambience and high gain before feedback. Thanks to the UniGuard RFI-shielding technology, the U891RWb impedes radio frequency interference from sources such as wireless devices, fluorescent lights, air conditioners, and more. It can be powered by 11 to 52 VDC phantom power, so no batteries or external power supplies are required. The rotatable balanced TB3M output connects to the included 25' TA3F to XLR microphone cable, ensuring easy hookup to your mixer, preamplifier, or audio interface.
