Shure Microflex® MX391 Series microphones are small, surfacemounted electret condenser microphones designed for mounting on conference tables, stage floors, and lecterns. Their high sensitivity and wide frequency range make them especially suitable for picking up speech and vocals in sound reinforcement and recording applications.

MX391 and MX391W (white) models have 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.
