MX391, MX392, and MX393 Microflex Boundary Microphones

MX391, MX392 and MX393 Microflex Wired Boundary Microphones from Shure are the smartest boundary microphones yet.  Equipped with features like programmable, silent membrane switches, logic inputs and outputs, and LED indicators, Microflex Boundary microphones are the high-quality solution for a range of applications, such as altars, boardrooms and distance learning centers. Every Microflex Boundary microphone features a choice of interchangeable condenser cartridges.

Available in cardioid, supercardioid and omnidirectional polar patterns, the Microflex cartridges give you superior Shure quality sound for every application. In addition, their programmable switches offer the flexibility to be set for Push to Talk, Push to Mute or Push On/Push Off modes. Attractively designed with a low profile, professional appearance, the Microflex Boundary microphones come with an easy to use paint mask for your custom-color installations. Find out why we call the Microflex Boundary microphones "the smart choice" for just about every application. Take a listen today.

The polar pattern of the cartridge is indicated by the model number suffix:

C = Cardioid, S = Supercardioid, O= Omnidirectional 

MX391:  Includes an attached 4 meter (12 ft) cable terminated with a 4-pin mini connector and a separate preamplifier. A rubber strain relief is provided for applications where you want to remove the 4-pin mini connector and connect the microphone cable directly to screw terminals in the preamplifier.
