Audio-Technica U891RWB Boundary Microphone
The U891RWB is a cardioid condenser boundary microphone with a built-in switch, finished in white to blend into a conference table or lectern. It sits flat on the surface and picks up talkers across the table, and a touch switch on top can be set to latch on and off, act as press-to-talk, or press-to-mute, giving each participant simple local control.
A PivotPoint rotating output connector lets the cable exit cleanly in any direction, and an LED indicates status at a glance. Phantom powered, it runs an 80 Hz low-cut to trim rumble and HVAC noise. It ships with a 25-foot white cable terminated with TA3F and XLRM connectors for a tidy boardroom install.
