The Audio Technica AT854R is a multi-channel boundary microphone with 4 cardioid condenser elements mounted in a single housing. It is ideal for high-quality sound reinforcement and a variety of video and audio conferencing applications, especially when used with an Audio-Technica automatic SmartMixer. Its low-profile design makes the AT854R suitable for use in applications where minimum visibility is required.
The four channels of the AT854R, mounted in quadrants, are separate and independent. They can be powered and used individually or in any combination. This permits system integrators to use their own proprietary DSP algorithms for microphone control when incorporating the AT854R into an existing system.
Requires phantom power.
