The new Engineered Sound. Contractor-exclusive innovations for every acoustical challenge. And safe haven from RFI.
This 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 colors: black (ES947) and white (ES947W).
