The Microflex Gooseneck microphones bring a whole new meaning to the word flexible. Beyond their fully adjustable goosenecks lies a new level of flexibility the new Microflex interchangeable condenser microphone cartridge. 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 new Microflex product line for enhanced convenience and consistent sound. Every Microflex Gooseneck features high sensitivity and balanced, transformerless output for maximum immunity to electromagnetic hum and RF interference, even over long cable runs.
