Description
The Shure Axient Digital ADX2FD/K8B is a high-performance frequency diversity handheld wireless transmitter built for professional productions that demand uncompromising RF reliability and audio clarity. Operating in the X55 band (941–960 MHz), this transmitter uses dual-carrier frequency diversity technology to transmit on two discrete RF signals simultaneously, significantly reducing dropouts and ensuring continuous, stable performance in congested RF environments.
Equipped with the KSM8 dual-diaphragm dynamic capsule, the ADX2FD/K8B delivers exceptional vocal accuracy with minimal proximity effect and consistent tonal balance. Designed for live sound, broadcast, and touring applications, it offers advanced features such as ShowLink® remote control for real-time adjustments, AES 256-bit encryption for secure transmission, and high-power output options for extended range and flexibility.
Its rugged metal construction, long-lasting rechargeable battery system, and seamless integration with Axient Digital receivers make it an ideal solution for mission-critical wireless audio systems.
