Shure ULXD2/SM58 G50 Digital Handheld Wireless Microphone

The Shure ULXD2/SM58 is a professional digital handheld wireless transmitter combining the industry-standard SM58 cardioid dynamic capsule with ULXD Series infrastructure. Operating in the G50 band (470–534 MHz), it uses Shure's 24-bit digital audio transmission with AES-256 encryption, delivering a clean, full-frequency signal over licensed spectrum. Designed for demanding live sound, broadcast, and large-venue production environments, it pairs with ULXD4 series receivers and integrates into Shure's Wireless Workbench software for centralized RF management. The transmitter supports up to 8 hours of operation on a single AA battery or Shure's SB900A rechargeable lithium-ion battery system.
