SHURE MX412D
Desktop Gooseneck Microphones
Desktop Base with 10′ Cable, Logic Functions, Programmable Switch, LED Indicator, Snap-Fit Foam Windscreen
Shure Microflex MX400D Series microphones are miniature electret condenser gooseneck microphones with a desktop base and attached 3 m (approximate)/10 ft cable. The desktop base allows these microphones to be used in multi-purpose rooms where quick set-up is required, or where permanent installation is impractical.
C = Cardioid, S = Supercardioid, N = No Cartridge
