Audio-Technica U841R Omnidirectional Condenser Boundary Microphone

The Audio-Technica U841R Omnidirectional Condenser Boundary Microphone is a high-quality, highly intelligible audio solution designed for various surface-mount applications. Its super-compact and low-profile design ensures minimal visibility, making it perfect for environments where discretion is key. The microphone boasts exceptional audio reproduction, characterized by its clear and high-output performance, thanks to its small-diameter omnidirectional capsule near the boundary, which eliminates phase distortion.

Equipped with Audio-Technica's exclusive UniGuard RFI-shielding technology, the U841R offers outstanding rejection of radio frequency interference (RFI), which ensures uninterrupted and high-quality sound transmission. Additionally, this unit features self-contained electronics, removing the need for any external power modules and simplifying installation and use.

The heavy die-cast case and non-slip silicon foam bottom pads are designed to minimize the coupling of surface vibrations to the microphone, ensuring steady and consistent audio capture. Whether for conferences, broadcast studios, or any other professional audio applications, the Audio-Technica U841R is a reliable choice that delivers premium audio clarity.
