Description
The Shure Axient Digital ADX2FDTA handheld wireless transmitter with SM58 capsule is engineered for mission-critical live sound, broadcast, and high-profile productions where RF stability and audio clarity are non-negotiable. Featuring frequency diversity transmission, this advanced handheld transmitter simultaneously broadcasts on two discrete RF carriers to significantly reduce signal dropouts and interference in congested environments.
Built with a durable, moisture-resistant metal housing, the ADX2FDTA integrates ShowLink remote control for real-time parameter adjustments and automatic interference avoidance. Paired with the legendary SM58 dynamic vocal capsule, it delivers consistent, industry-standard vocal performance with exceptional intelligibility and feedback rejection.
With wide tuning across the 470–616 MHz band and support for high-density mode, this transmitter ensures maximum channel count and spectral efficiency. Designed for enterprise-grade deployments and professional touring, it provides secure, encrypted transmission and seamless integration with Shure Axient Digital wireless systems.
