Shure MX392/O Omnidirectional Boundary Microphone Featuring Logic-Control LED for Installation (Back Cable Exit, Unterminated Pigtail) | MX392/O
In a wood-paneled council chamber, a glass-walled conference room, or a university lecture hall where every syllable counts, the microphone shouldn’t call attention to itself. It should disappear into the conference table.
- The MX392/O’s unterminated pigtail terminates in a back cable exit, letting you run the wire cleanly into the table surface for installations that look sleeker both underneath and on top. No dangling loops of cable.
- The logic-control LED frees the integrator to wire status indication straight into a DSP or control system ? a practical tool for muting indicators and visual callback during meetings rather than a cosmetic light show.
- Its omnidirectional polar pattern picks up voices from all around the table with uniform clarity, meaning no one has to lean in or speak up as the mic sits flush against the boundry surface.
- The un-terminated tail gives the installer freedom to terminate directly to the pre-wired system panel or conduit, saving adapters and shortening the signal path.
This boundary microphone is built for the hands of a technician who needs the install to be clean, the signal chain to be flexible, and the conversation to flow. No fuss.
