Shure ULXD2/SM58 Handheld Mic Transmitter w/ SM58 Capsule (Frequency Band H54)

Shure's ULXD2/SM58 is a digital handheld wireless transmitter built for touring musicians, studio engineers, and live sound operators who demand reliability and transparent audio. The unit pairs the legendary SM58 capsule with Shure's ULX-D digital backbone, delivering the workhorse performance that's defined vocal capture for decades—now with modern wireless security and battery management that cuts setup time on gig days.

The transmitter operates across a 30 Hz–20 kHz frequency range with flat response, controlled via backlit LCD menu and easy navigation. AES 256-bit encryption secures transmission for sensitive applications, whilst proprietary Gain Ranging automatically optimises dynamic range without manual transmitter adjustments. A lithium-ion rechargeable battery lasts over 9 hours per charge with precision metering in hours and minutes, and zero memory effect. External charging contacts dock with the SBC200 Dual Docking Charger for rapid turnaround between sets. Rugged aluminium construction with integrated antenna handles the road; interchangeable Shure cartridges (SM58, Beta 58A, KSM8, and others) allow capsule swaps to match different vocal styles or applications.

The H54 frequency band sits in the crowded live sound spectrum, ideal for venues and touring rigs already running digital wireless infrastructure. Frequency and power lockout settings prevent accidental drift during performances. Compatibility with the full ULX-D ecosystem means pairing with matching receivers, networked docking chargers, and spare battery configurations tailored to multi-mic setups and long festival runs.
