Shure Cardioid - Condenser Boundary Microphone, Built-in Preamp, Attached 12' Unterminated Bottom-exit Cable, Logic Functions, Programmable Switch and LED Indicator

The Shure MX392BE/C is a professional boundary microphone in the Microflex® series designed for surface‑mount applications. It features a built‑in preamplifier, a bottom‑exit attached unterminated cable, and a low‑profile design that makes it suitable for installations in boardrooms, conference rooms, altars, classrooms, and other environments where unobtrusive sound capture is needed. The microphone uses a cardioid condenser capsule and includes programmable switch and logic control functions for flexible use with external systems.
