Audio Technica U891Rb Cardioid Condenser Boundary Microphone with Programmable Switch
Audio‑Technica U891Rb Cardioid Condenser Boundary Microphone with Programmable Switch
- Low‑profile cardioid condenser boundary microphone for conferencing and boardrooms
- Touch‑sensitive capacitive switch with three selectable operating modes
- Two‑state RGB LED status indicator for clear microphone status
- PivotPoint® rotating output connector for flexible cable routing
- Rugged, self‑contained design with UniGuard® RFI protection
The U891Rb is a versatile condenser boundary microphone designed to deliver clear, intelligible audio with intuitive user control in conference rooms, boardrooms, and other installed sound applications. Its compact, low‑profile form factor blends seamlessly into professional environments while providing reliable performance.
Featuring a touch‑sensitive capacitive‑type user switch, the U891Rb can be configured for touch on/off, touch‑to‑talk, or touch‑to‑mute operation. The microphone’s self‑contained electronics eliminate the need for an external power module, simplifying installation.
User Control & Visual Status
An integral, phantom‑powered two‑state RGB LED indicator displays microphone on/off status, providing immediate visual feedback for users. The LED indicator is designed for clear visibility while maintaining a clean, unobtrusive appearance.
Audio Performance
- Cardioid polar pattern with 120° acceptance angle
- Frequency response: 20 Hz – 20 kHz
- Dynamic range: 104 dB
- Maximum SPL: 130 dB
- 80 Hz UniSteep® low‑cut filter to reduce low‑frequency ambient noise
Flexible Installation & Design
The PivotPoint® rotating output connector allows the microphone cable to exit from either the rear or the bottom of the unit, providing flexibility for clean, discreet installation. Threaded inserts on the bottom of the microphone allow secure mounting with screws when required.
A heavy die‑cast case with non‑slip silicone foam bottom pads minimizes coupling of surface vibration to the microphone, ensuring consistent audio quality in demanding environments.
Advanced Audio‑Technica Technologies
- UniGuard® RFI‑shielding technology for outstanding rejection of radio‑frequency interference
- UniPoint® element design minimizes phase distortion and delivers clear, high‑output performance
- Superior off‑axis rejection for maximum gain before feedback
Connectivity & Power
- Integral output connector with PivotPoint® rotation
- Phantom power requirement: 11–52 V DC
- Current consumption: 9.3 mA
Included Accessories
- Soft protective pouch
Ideal Applications
- Conference rooms and boardrooms
- Corporate and institutional meeting spaces
- Courtrooms and council chambers
- Professional recording and sound reinforcement installations
