Overview

The Shure SLXD4D+ dual-channel half-rack receiver gives you reliable digital wireless performance for touring and installation applications. Built for smooth operation in real-world RF conditions, it delivers transparent 24-bit digital audio with more than 118 dB of dynamic range and a wide 138 MHz tuning window for dependable wide-range coverage. Once paired, SLX-D+ receivers and transmitters stay locked together using ShowLink® Ease, automatically scanning, updating, and maintaining clear transmission even as conditions change. You can also monitor and adjust system settings directly from a paired mobile device, keeping control simple, fast, and in the palm of your hands.

Designed with modern system management in mind, the SLXD4+ lets you remotely adjust transmitter frequency and gain, deploy new channels when interference appears, lock controls, update firmware, and even link a second transmitter to the same receiver channel. Wireless Workbench desktop software and the WWB Mobile app give you detailed RF monitoring and system control over Wi-Fi or Bluetooth, while built-in Shure Digital Feedback Reducer software actively minimizes feedback before it becomes a problem. AES-256 encryption comes standard for secure operation, and the rugged metal half-rack chassis fits cleanly into touring racks or fixed installs, making the SLXD4+ a reliable foundation for the professional wireless systems you trust night after night.
