Description
Audio-Technica U891RBO Omnidirectional Boundary Microphone is a professional conference boundary microphone designed for boardrooms, meeting rooms, and conferencing systems. This omnidirectional boundary microphone captures clear speech from all directions, making it ideal for table-mounted conference applications, teleconferencing, sound reinforcement, and broadcast environments.
The U891RBO boundary microphone features a touch-sensitive mute switch with selectable modes including touch on/off, push-to-talk, and touch-to-mute. A built-in RGB LED indicator clearly shows microphone status, helping users manage meetings smoothly. The PivotPoint® rotating output connector allows flexible cable routing from the rear or bottom for clean installations.
Engineered for reliable performance, this condenser boundary microphone includes UniGuard® RFI shielding to reduce radio frequency interference and an 80 Hz low-cut filter to minimize low-frequency noise such as table vibrations and room rumble. The heavy die-cast housing and non-slip silicone base reduce surface noise, while threaded mounting points provide secure permanent installation.
Phantom-powered operation and self-contained electronics eliminate the need for an external power module, making the Audio-Technica U891RBO an excellent choice for conference rooms, boardrooms, government facilities, classrooms, and corporate AV installations requiring a low-profile omnidirectional boundary microphone.
