Description
The Shure Axient Digital ADX2FD/K8B is a premium frequency diversity handheld wireless transmitter engineered for mission-critical live sound, broadcast, and high-end production environments. Operating in the X55 band (941–960 MHz), this transmitter delivers exceptional RF stability by simultaneously transmitting on two discrete carriers, significantly reducing dropouts and ensuring uninterrupted performance even in congested RF conditions.
Built with Shure’s advanced Axient Digital platform, the ADX2FD combines pristine audio quality, ultra-low latency, and robust encryption for secure transmission. The included KSM8 Dualdyne dynamic microphone capsule (black finish) provides consistent vocal clarity with excellent off-axis rejection, making it ideal for demanding vocal applications.
With ShowLink® remote control capability, engineers can monitor and adjust transmitter parameters in real time without interrupting performance. Its durable metal construction, extended battery life, and flexible RF output options make it a trusted solution for touring professionals, broadcast engineers, and enterprise AV deployments.
