The ES947 low-profile cardioid condenser boundary microphone is designed for clear, highly intelligible sound reinforcement, professional recording and teleconferencing in table-, ceiling-, or panel-mount applications. The microphone is equipped with self-contained power module with an XLRM-type output connector, eliminating the need for an external power module. Protected by rugged all-metal case with two-layer steel mesh grille, the microphone has cardioid pattern for enhanced gain before feedback and improved signal-to-noise ratio.
