Shure MX393/O-TA Microflex Omnidirectional Boundary Microphone for ...
The Shure MX393/O is a professional boundary condenser microphone from the Microflex series, designed for clear, natural speech capture in conference rooms, boardrooms, altars, and distance learning centers. It features an omnidirectional polar pattern that provides uniform pickup from all directions, making it ideal when natural ambient sound is desired or when the talker may move.
The low-profile design ensures a discreet, professional appearance on any surface. It includes a programmable silent membrane switch with multiple modes (push-to-talk, push-to-mute, push on/push off), LED indicator, and logic connections for integration with automatic mixing systems. CommShield Technology delivers superior RF rejection. A paint mask is provided for custom-color installations, and the microphone uses interchangeable condenser cartridges for flexibility.
