About Audio-Technica U891RWB

If you're seeking superior audio quality for your conference or boardroom installations, consider the U891RWB Cardioid Condenser Boundary Microphone. This versatile, phantom-powered microphone is designed with a touch-sensitive capacitive user switch, offering three distinct modes for maximum flexibility: touch on/off, touch to talk, and touch to mute.

This high-performance microphone is equipped with a unique PivotPoint rotating output connector, enhancing its adaptability to your setup. It also features a two-state RGB LED status indicator, providing clear, visual feedback on the microphone's status.

One of the standout features of the U891RWB Cardioid Condenser Boundary Microphone is its UniGuard technology. This innovative feature ensures unparalleled immunity from radio frequency interference, guaranteeing clear, uninterrupted audio.

For those seeking to customize their sound, interchangeable elements are available separately in hypercardioid and omnidirectional polar patterns. The microphone also includes an 80 Hz low-cut UniSteep filter, effectively reducing the pickup of low-frequency ambient noise for a cleaner, more focused sound.

The U891RWB is built to last, with a heavy die-cast case and silicon foam bottom pads. These features not only ensure durability but also minimize the coupling of surface vibration to the microphone, resulting in a smoother audio output. For added security, threaded inserts on the bottom of the microphone allow for secure mounting with screws.

The self-contained electronics of this microphone eliminate the need for an external power module, making it a convenient, all-in-one solution for your audio needs. With its advanced features and robust design, the U891RWB Cardioid Condenser Boundary Microphone is a reliable choice for professional audio capture.

  • UniGuard RFI-shielding technology offers outstanding rejection of radio frequency interference (RFI)
  • Self-contained electronics eliminate need for external power module
