Audio-Technica U891Rb

Audio-Technica U891Rb

Cardioid condenser boundary microphone. Designed to deliver easy, flexible control in conference and boardroom installations, the versatile U891Rb cardioid condenser boundary microphone features a touch-sensitive capacitive-type user switch that can be set to three modes: touch on/off, touch to talk, and touch to mute. The phantom-powered microphone is equipped with a unique PivotPoint rotating output connector and a two-state RGB LED status indicator. UniGuard innovations offer unsurpassed immunity from radio frequency interference. The microphone’s heavy die-cast case and silicon foam bottom pads minimize coupling of surface vibration to the microphone, while threaded inserts on the bottom of the microphone allow it to be mounted with screws for increased security. The unit’s self-contained electronics eliminate the need for an external power module.
