Audio Technica ES947W - Cardioid Condenser Boundary Microphone

This low-profile Audio Technica ES947W cardioid condenser boundary microphone is recommended for unobtrusive table, ceiling, or panel-mount applications in high-quality sound reinforcement, professional recording and teleconferencing. Designed for permanent installation, the microphone is equipped with a self-contained power module with an XLRM-type output connector, eliminating the need for an external power module.

Protected by a rugged all-metal case with a two layer steel mesh grille, the microphone has a cardioid pattern for enhanced gain before feedback and improved signal-to-noise ratio.
