The Shure ADX2/K9HS is a premium handheld wireless transmitter that integrates the advanced, dual-voiced KSM9HS condenser microphone capsule with the robust and intelligent Axient Digital wireless platform. This system is engineered for the most critical vocal applications where sonic excellence, reliability, and control are non-negotiable, such as major concert tours, broadcast television, and high-profile live events. The KSM9HS capsule is renowned for its studio-quality clarity and offers a user-selectable voicing switch, allowing performers to choose between a flat, natural response for transparent sound reproduction and a presence-boosted curve that enhances vocal articulation and cut-through in a dense live mix.

The transmitter body houses the sophisticated electronics of the Axient Digital system, providing high-fidelity digital audio transmission with an exceptionally wide dynamic range and a noise floor so low it is virtually inaudible. The platform incorporates advanced RF management tools, including interference detection and frequency coordination, ensuring reliable operation in the most congested wireless environments. As part of the Axient Digital ecosystem, it supports ShowLink two-way communication, enabling remote control and monitoring of transmitter parameters like gain and RF power directly from the mixing console or system manager software—a critical feature for making adjustments without stage access during a live show.

Constructed with a rugged metal body and a hardened steel grille, the transmitter is built to withstand the physical demands of touring. It features an intuitive OLED display for monitoring status and is powered by a high-capacity rechargeable lithium-ion battery. The ADX2/K9HS represents the confluence of state-of-the-art transducer technology and cutting-edge wireless intelligence, delivering uncompromising audio performance and system control for elite professional applications.
