Wireless that works as hard as you do. The SLXD24D+B58 system brings wireless freedom, system control, and world-class Shure audio to all your performance, broadcast, and location sound events. Built on the SLX-D+ platform, it offers transparent 24-bit digital audio with over 118dB of dynamic range and a wide 138MHz tuning range for rock-solid RF stability. Once linked, transmitters and receivers stay connected even in today's 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. RF performance stays locked in with ShowLink acting as your invisible assistant that scans, updates, and manages interference before you even notice. And thanks to mobile monitoring, your phone is your command center, giving you oversight from anywhere in any venue. Oversight is simple with Wireless Workbench or WWB Mobile via Wi-Fi or Bluetooth. Embedded AES-256 encryption ensures your signal only reaches the ears you intend, and Shure’s patented Digital Feedback Reducer actively suppresses unwanted feedback, so those ears hear it all clearly. Inside the case: an SLXD4D+ dual-channel receiver matched with a pair of SLXD2+ handheld transmitters. Crafted with legendary Shure durability and infused with the sound of a Beta 58A capsule, the SLXD2+B58s deliver the high output, focused sound preferred by vocalists and engineers for over 30 years.
