Features
• Designed for surface-mount applications such as sound reinforcement
• Ultra-quiet electronic switch
• 3 operating modes: Touch-on/ touch-off ; Touch-to-talk and Touch-to-mute
• Superior off-axis rejection for maximum gain before feedback
• UniGuard® RFI-shielding technology offers outstanding rejection
• Available in two colors: black (U891Rx) and white (U891RWx)
| 
| Designed to deliver easy, flexible control in conference and boardroom installations, the versatile U891RWx cardioid condenser boundary microphone features a 
touch-sensitive on-off switch that can be set to three modes: press-on/press-off, press to talk, and press to mute. The phantom-powered microphone is equipped with a unique PivotPoint® 
rotating output connector and an LED status indicator. UniGuard® innovations offer unsurpassed immunity from radio frequency interference; interchangeable elements are available in cardioid, 
hypercardioid and omnidirectional polar patterns; an 80 Hz low-cut UniSteep® filter reduces pickup of low-frequency ambient noise. The microphone's heavy die-cast case and silicon foam bottom pads minimize 
coupling of surface vibration to the microphone. The unit's self-contained electronics eliminate the need for an external power module. |
