The Audio-Technica ES945O/FM5 Omnidirectional Condenser Boundary Microphone is a 5-pin, phantom-powered device featuring a self-contained power module, Logic I/O, and an RGB LED ring with seven selectable colors to indicate mute status.

The Audio-Technica ES945O/FM5 is an omnidirectional condenser boundary microphone designed for high-quality sound pickup in conferencing, recording, and monitoring environments. This phantom-powered microphone features a 5-pin XLR output and a touch-sensitive capacitive-type user switch for remote muting and device control. It mounts unobtrusively into tabletops or panels to provide clear, intelligible audio in professional boardroom installations.
The ES945O/FM5 includes Logic I/O capability, allowing the microphone to control remote devices via its touch-sensitive capacitive-type user switch. Using the microphone’s external contact closure, users can trigger external equipment such as cameras or room lighting. The switch is also configurable to toggle between mute and live audio states, providing enhanced control during meetings.
A highly visible two-state RGB LED ring provides immediate visual feedback regarding the microphone's status. This ring offers seven selectable colors plus an OFF setting, keeping users apprised of whether the audio is live or muted. This feature is integrated directly into the low-profile housing for a clean aesthetic.
The microphone utilizes an omnidirectional polar pattern to provide 360° coverage, ensuring uniform sound pickup from all directions. It features UniGuard RFI-shielding technology, which offers outstanding rejection of radio frequency interference (RFI) to maintain signal integrity. The low-profile element is specifically engineered for demanding sound pickup applications where intelligibility is a priority.
Built for durability, the ES945O/FM5 features a rugged all-metal case and a two-layer steel mesh grille to protect the internal microphone element. The unit contains a self-contained power module, which eliminates the need for an external power source. For installation, the package includes a pair of rubber isolators that provide mechanical dampening to reduce vibration from the mounting surface.
