User Manual

MULTIDIRECTIONAL CONDENSER BOUNDARY MICROPHONE

U843R

Introduction

Thank you for purchasing this Audio-Technica product.

Before using the product, please read through the Quick Start Guide, as well as

this user manual when necessary, to ensure that you use the product correctly.

Features

•Designed for surface-mount applications, such as high-quality sound

reinforcement, and to provide total coverage of round or long tables with fewer

microphones.

•Small-diameter microphone capsule near boundary eliminates phase distortion

and delivers clear, high-output performance.

•Durable brass-carved frame and non-slip high-performance urethane foam

bottom pads minimize coupling of surface vibration to the microphone.

•Low-profile design with low-reflectance finish for minimum visibility.

•U843R is ideal for a variety of video and audio conferencing applications,

especially when used with an Audio-Technica automatic SmartMixer™.

Connection procedure

Output from the microphone is low impedance (Lo-Z) balanced. The signal

appears across the pairs of colored wires (red and yellow wires for Ch1, white

and blue wires for Ch2, and green and brown wires for Ch3); audio ground is the

shield connection. Output is phased so that positive acoustic pressure produces

positive voltage on the yellow, green and white wires.
