Acting Shure MX418D conference microphone

Microflex Gooseneck microphones new interpretation of a flexible real meaning. In addition to fully adjustable gooseneck, there is more flexibility in the new Microflex interchangeable condenser microphone head. Interchangeable cartridges have easy replacement design, and make intentions shaped, super-cardioid and omnidirectional pickup pattern, providing wide frequency response and precision for a variety of applications (such as churches, courtrooms and conference centers) sound reproduction. In addition, condenser microphone head is suitable for each model of new Microflex product line, making it easy to use and has a consistent sound quality. You can choose from four types of Microflex gooseneck microphone, but can also choose a variety of heights and fixed type. Each model includes a Shure Microflex series of unique silent mute switch with LED indicator. And each Microflex gooseneck microphones with high sensitivity and balanced, transformerless output can be improved electromagnetic hum and RF interference immunity, even by long-distance cable transmission.
