Audio-Technica U891Rb: Cardioid Condenser Boundary Microphone with Switch, Black
The Audio-Technica U891Rb Cardioid Condenser Boundary Microphone is meticulously engineered to offer reliable, easy-to-use, and flexible control in conference and boardroom settings. This versatile microphone features a touch-sensitive capacitive-type user switch that can be set to three different functions: touch on/off, touch to talk, and touch to mute. Supplied by Trianze Tech across Dubai, Abu Dhabi, the UAE and the GCC.
Key Features:
- Cardioid condenser boundary microphone with touch-sensitive capacitive-type user switch

- The capacitive touch switch can be set to any of three operating modes: touch on/off, touch to talk, and touch to mute
- Integral, phantom-powered, two-state RGB LED indicator displays on/off status of the microphone
- Superior off-axis rejection for maximum gain before feedback
- PivotPoint rotating output connector allows the cable to exit from either the rear or the bottom of the microphone
- Small-diameter UniPoint element near boundary eliminates phase distortion and delivers clear, high-output performance
