Audio-Technica U891RWb Cardioid Condenser Boundary Microphone with Switch, White

The Audio-Technica U891RWb is a versatile cardioid condenser boundary microphone designed to meet the demanding needs of conference and boardroom installations. Its touch-sensitive capacitive-type user switch allows for flexible user control, offering touch on/off, touch to talk, and touch to mute modes. With a unique PivotPoint rotating output connector and a two-state RGB LED status indicator, this microphone is ideal for professional applications requiring high-quality sound reinforcement and conferencing solutions.

Phantom-powered and designed for maximum gain before feedback, the U891RWb ensures superior off-axis rejection and clear, high-output performance. Equipped with UniGuard RFI-shielding technology, this microphone excels in rejecting radio frequency interference, ensuring pristine audio quality. The built-in UniSteep low-cut filter at 80 Hz minimizes low-frequency ambient noise, making it an excellent choice for various recording environments. The heavy die-cast case and silicon foam bottom pads reduce surface vibration to deliver clear audio without interference.

Featuring self-contained electronics, the U891RWb eliminates the need for external power modules, allowing for straightforward installation. Available in a sleek white finish, this microphone's low-profile design ensures it remains unobtrusive in any setting, while the option to mount it with screws enhances its security.
