About Audio-Technica U843R

While maintaining a sleek, black design, the U843R Three Cardioid Condenser Elements Multidirectional Boundary Microphone, powered solely by phantom power, is a testament to Audio-Technica's innovative and professional audio solutions. This high-quality microphone is equipped with three cardioid condenser elements housed in a single, durable unit, making it a versatile tool for surface-mount installations.

Primarily designed for a wide range of audio and video conferencing applications, this microphone is an optimal choice when paired with an Audio-Technica automatic SmartMixer. The base of the microphone features easy-to-use levers that allow for swift reorientation of two elements, providing coverage options of either 360 degrees or 300 degrees.

The U843R's unique design allows for each element to be powered and used individually or in combination, offering unparalleled flexibility. For instance, powering two elements can create a figure-of-eight polar pattern, while using a single element transforms the microphone into a standard cardioid boundary microphone.

Installation and repositioning are made effortless with four recessed pathways on the microphone's base, enabling the user to route the cable as needed to meet any installation requirements, without the need for tools or disassembly.

Moreover, this reliable microphone is equipped with Audio-Technica's innovative UniGuard RFI-shielding technology, ensuring clear, uninterrupted sound. Whether you're a professional in the audio industry or an enthusiast seeking superior sound quality, the U843R Three Cardioid Condenser Elements Multidirectional Boundary Microphone is a reliable choice, brought to you by Adorama, your trusted source for top-tier audio and video equipment.
