Audio-Technica ES947

The Audio-Technica ES947 is a low-profile 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. It is available in two colours: black (ES947) and white (ES947W).
