The Shure ADX2FD/K8 is a professional digital handheld wireless microphone transmitter that pairs the advanced ADX2 wireless platform with the premium KSM8 Dualdyne™ microphone capsule. This combination delivers exceptional audio quality, robust RF performance, and unparalleled handling noise rejection for the most demanding live sound and broadcast applications. The ADX2 transmitter operates on a user-selectable frequency in the designated band (indicated by "K8"), leveraging Shure's superior digital transmission to provide crystal-clear audio with a wide dynamic range, free from compander noise and dropout. The system features 24-bit/48 kHz digital audio quality, 128-bit AES encryption for secure transmission, and Intelligent Diversity™ to ensure a stable RF link even in challenging wireless environments.

The defining component of this system is the integrated KSM8 Dualdyne™ capsule, a revolutionary dynamic microphone element known for its exceptional off-axis rejection and virtually non-existent handling noise. The capsule's unique design incorporates two diaphragms and a patented internal shock mount that mechanically isolates the transducer from vibrations transmitted through the handheld body. This results in exceptionally clean audio capture where plosives, rumble from hand movements, and background noise are dramatically reduced, allowing the performer's voice to cut through the mix with pristine clarity. The KSM8 is also revered for its smooth, natural frequency response tailored for vocal reinforcement.

Built to professional touring standards, the transmitter features a durable metal housing, intuitive OLED menu for configuring settings like frequency and power output, and a long-lasting rechargeable battery system compatible with Shure's SB900 charging ecosystem. The system integrates seamlessly with Shure's Axient Digital wireless ecosystem, offering features like ShowLink™ remote control and monitoring via Wireless Workbench software, and compatibility with Quadversity for the ultimate in RF reliability. By marrying the industry-leading KSM8 vocal capsule with the cutting-edge ADX2 digital wireless platform, this handheld microphone provides top-tier vocalists, presenters, and broadcasters with a wireless tool that offers uncompromised sonic integrity and rock-solid performance.
