The right speech doesn’t just inform. It can excite and even transform those who hear it. So, we designed the MX412 to treat spoken audio with the detail and respect it deserves. Because clarity commands attention.
Designed for easy replacement and available in cardioid, supercardioid and omnidirectional polar patterns, the interchangeable cartridges offer wide frequency response and accurate sound reproduction for a broad variety of applications, such as houses of worship, courtrooms and conference centers. Plus, the condenser cartridges fit every model in the Microflex product line for enhanced convenience and consistent sound.
