The Audio-Technica ES947C/FM5 Cardioid Condenser Boundary Microphone is a black, 5-pin phantom-powered microphone featuring a self-contained power module, Logic I/O, and an RGB LED ring with seven selectable colors plus an off setting to indicate mute status.
The Audio-Technica ES947C/FM5 is a professional cardioid condenser boundary microphone designed for clear and intelligible audio capture in conferencing, recording, and monitoring environments. This phantom-powered microphone mounts unobtrusively into tabletops or panels, providing a low-profile solution for boardroom installations and other demanding sound pickup applications.
The ES947C/FM5 features a touch-sensitive capacitive-type user switch that allows for seamless control during meetings. This switch toggles between mute and live audio states while utilizing Logic I/O capability to permit the control of remote devices. Through the microphone’s external contact closure, users can trigger external equipment such as room lighting or camera systems. A highly visible two-state RGB LED ring provides immediate status feedback, offering seven selectable colors and an off mode to keep users apprised of the microphone's current state.
A low-profile element delivers a uniform cardioid polar pattern with a 120° acceptance angle for precise sound pickup. To ensure signal integrity, the microphone incorporates UniGuard RFI-shielding technology, which provides outstanding rejection of radio frequency interference (RFI). The system operates on 11V to 52V DC phantom power and includes a self-contained power module, which eliminates the need for external power components. The 5-pin XLR output connector facilitates professional connectivity for remote muting and integration.
Built for durability, the ES947C/FM5 features a rugged all-metal case and a two-layer steel mesh grille to protect the internal microphone element. The package includes a pair of rubber isolators that provide mechanical dampening to isolate the microphone from mounting-surface vibrations. This model is both TAA-compliant and RoHS compliant, ensuring it meets specific regulatory standards for hazardous substances and trade agreements.
