Shure MX 412 S/C Microphone, cardioid

The Shure MX412S/C Microflex 12" Gooseneck Microphone, Cardioid. High quality and efficiency for installed audio applications.

The Shure MX412S/C Microflex 12 inch Gooseneck Microphone is part of the highly flexible Microflex Gooseneck microphone range. Beyond their fully adjustable goosenecks lies a new level of flexibility in the Microflex interchangeable condenser microphone cartridge (a Cardioid cartridge is included with this MX412S/C model). 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.

Microflex Gooseneck microphones are available in four models with a variety of heights and mounting styles to choose from. One model includes a silent mute switch with LED indicator, a Shure Microflex exclusive. And every Microflex Gooseneck features high sensitivity and balanced, transformerless output for maximum immunity to electromagnetic hum and RF interference, even over long cable runs.

This model is the MX412S/C (Cardioid) 305 mm (12 inch) gooseneck, attached XLR preamp, Shock Mount, flange mount, snap-fit foam wndscreen, mute switch, LED Indicator.
