Over the course of your professional audio recording and broadcasting endeavors, the Audio-Technica U891RB Cardioid Condenser Boundary Microphone stands out as a sophisticated and reliable choice. This durable microphone is designed with a sleek black finish, ensuring it not only performs exceptionally but also maintains a stylish presence in any conference room, boardroom, or recording studio.
The U891RB features a touch-sensitive capacitive-type user switch, offering unparalleled flexibility with three selectable modes: touch on/off, touch to talk, and touch to mute. This functionality allows for seamless audio control during live events or in fixed installations. The microphone's advanced phantom power capabilities ensure consistent performance without the need for an external power module, streamlining your setup and reducing clutter.
Equipped with Audio-Technica's proprietary PivotPoint rotating output connector, the U891RB can be easily adjusted to suit the specific requirements of your recording environment. Additionally, the two-state RGB LED status indicator provides clear visual cues for the operational mode, enhancing user interaction and control.
The U891RB is engineered with UniGuard technology, offering unmatched immunity to radio frequency interference, a common challenge in today's electronically dense environments. For those seeking versatility, additional interchangeable elements are available separately, allowing you to customize the microphone with hypercardioid or omnidirectional polar patterns to suit various acoustic conditions.
An integrated 80 Hz low-cut UniSteep filter effectively reduces the pickup of unwanted low-frequency ambient noise, ensuring that your recordings are crisp and clear. The microphone's robust die-cast case, combined with silicon foam bottom pads, significantly minimizes the transmission of surface vibrations, preserving the integrity of the audio signal.
For added security, especially in public or multi-use spaces, the U891RB includes threaded inserts on the bottom, enabling it to be securely mounted with screws. This feature ensures that the microphone remains in place, providing consistent audio capture and reducing the risk of tampering or accidental displacement.
In summary, the Audio-Technica U891RB Cardioid Condenser Boundary Microphone with Switch, RGB LED, and Integral Power Module is a high-quality, professional-grade audio solution that offers reliability and flexibility for a wide range of sound reinforcement, broadcasting, and recording applications.
