Shure Omnidirectional - Miniature White Condenser Boundary Microphone, 12' Attached Cable, Detachable Preamp with XLR

The Shure MX391W‑A/O is a boundary condenser microphone designed for professional speech reinforcement and conferencing applications. It has a low‑profile surface‑mount form factor that sits unobtrusively on tables, lecterns, or other surfaces, making it suitable for boardrooms, conference rooms, educational facilities, houses of worship, and other venues. The microphone uses an omnidirectional polar pattern to capture sound equally from all directions, helping ensure clear and intelligible vocal pickup. It includes an in‑line preamplifier and a 12‑foot attached cable terminated with a 4‑pin mini connector for flexible installation. Phantom power is required for operation.
