Shure SLXD24+/58-G57
The Shure SLXD24+/58 system brings wireless freedom, system control, and world-class Shure audio to performance, broadcast, and location sound events. Built on the SLX-D+ platform, it offers transparent 24-bit digital audio with over 118 dB of dynamic range and a wide 138 MHz tuning range for rock-solid RF stability. Once linked, transmitters and receivers stay connected even in overloaded wireless environments, with automatic frequency management ensuring clear transmission at all times.
ShowLink® technology puts control in your hands, allowing remote adjustment of transmitter parameters directly from the receiver, including frequency changes, gain settings, and firmware updates. Mobile monitoring makes your phone a command center, giving you oversight from anywhere in the venue.
System oversight is simple with Wireless Workbench® or WWB Mobile via Wi-Fi or Bluetooth. Embedded AES-256 encryption keeps your signal private, and Shure's patented Digital Feedback Reducer actively suppresses unwanted feedback.
The system pairs an SLXD4+ receiver with an SLXD2+ handheld transmitter, crafted with Shure durability and fitted with the iconic SM58® capsule that has defined live vocal sound for decades.
