Shure QLXD2/B58A Handheld Transmitter with Beta 58A Capsule — H50 (534-598 MHz)
QLXD2/B58A Overview
The Shure QLXD2/B58A combines the QLXD2 handheld transmitter with the legendary Beta 58A capsule, purpose-built for professional wireless vocal applications. Operating in the H50 band (534-598 MHz), it delivers transparent 24-bit digital audio quality with highly efficient RF spectrum usage, making it well-suited for RF-congested environments. The transmitter maintains a clear, uninterrupted signal over a 100 m (330 ft.) operating range, with IR sync to a compatible QLXD receiver at the push of a button. It is an ideal solution for audio engineers, system integrators, and technical directors serving music venues, presentation spaces, and houses of worship.
All-metal construction provides the durability required for touring and installed applications, while the straightforward IR sync workflow minimizes setup time and reduces the potential for operator error.
