This phantom-powered cardioid condenser boundary microphone features a 3-pin XLR output connector with a capacitive touch switch that enables local muting of the microphone.

Designed for clear, highly intelligible conferencing, recording, monitoring and other demanding sound pickup applications, the ES947C/FM3 mounts unobtrusively in tabletops or panels, but includes a highly visible two-state RGB LED ring (7 selectable colours + OFF) to indicate mute status.

The microphone’s cardioid polar pattern provides a 120° pickup angle. A rugged all-metal case with a two-layer steel mesh grille protects the microphone element, while our UniGuard® RFI-shielding technology provides outstanding rejection of radio frequency interference (RFI).

The ES947C/FM3 is equipped with a self-contained power module, eliminating the need for an external one, and comes with a pair of rubber isolators for optional mechanical isolation from the mounting surface.
