Audio-Technica U891RCb Cardioid Condenser Boundary Microphone with Local or Remote Switching, Black

The Audio-Technica U891RCb is a premium cardioid condenser boundary microphone designed for professional sound reinforcement, conferencing, recording, and broadcasting. This state-of-the-art microphone is equipped with both local and remote switching options, making it incredibly versatile for a wide range of applications. Its touch-sensitive capacitive-type switch can be seamlessly configured to operate in three different modes: touch-on/touch-off, press to talk, and press to mute, providing users with flexible control. The microphone also boasts external contact closure capabilities, allowing the user to trigger external devices, such as cameras, enhancing the functionality of your audio-visual setup.

Constructed with a heavy die-cast case and silicone foam bottom pads, the U891RCb minimizes surface vibration, ensuring crystal-clear sound quality. The microphone's two-state RGB LED status indicator can be controlled remotely, making it easy to monitor its status. With UniGuard RFI-shielding technology, this microphone offers exceptional immunity from radio frequency interference, making it ideal for professional environments. Additionally, the U891RCb features a unique PivotPoint rotating connector, enabling the cable to exit from either the rear or the bottom of the microphone without requiring tools. The self-contained electronics eliminate the need for an external power module, further simplifying the setup process.
