audio-technica Multidirectional Condenser Boundary Microphone

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.
A small-diameter microphone capsule near the boundary eliminates phase distortion and delivers clear high-output performance.
Durable brass-carved frame and non-slip high-performance urethane foam bottom pads minimize the 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 SmartMixerTM.

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); the audio ground is the shield connection. Output is phased so that positive acoustic pressure produces positive voltage on the yellow, green and white wires.
