Shure | MX412D/C - Cardioid condenser Microphone

Shure - MX412D/C - Cardioid condensor microphone with attached desktop base

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. Each Microflex Gooseneck microphone comes with a complete installation kit, including locking metal and foam ball windscreens, snap-in and shock-mount microphone stand adapters.
