Audio-Technica ES947C/FM3 Cardioid Condenser Boundary Microphone with 3-Pin XLR Output and Local Muting
Overview:
ES947C/FM3
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 colors + 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.
