The AT854R is a multi-channel boundary microphone with four 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.
The AT854R requires 9 - 52v DC phantom power for each operating channel. A 9.1 m cable with a miniature multicontact metal-body plug for connecting to the microphone is included. The cable is custom manufactured with four separate shielded and jacketed pairs inside a rugged overall jacket. The AT854R 'soutput end has four XLRM-type connectorsfor plugging into a mixer, allowing individual control of each channel. The microphone is enclosed in a rugged case and protected by two layers of perforated steel. The combination of heavy case and rubber non-slip bottom pad minimises mechanical coupling of surface vibrations to the microphone. The low-profile housing has a low-reflectance black finish.
