Shure SLXD4D+ Dual-Channel Digital Wireless Receiver - Band G57

The Shure SLXD4D+ digital wireless receiver is a dual-channel, half-rack receiver designed to serve as a centralized control, monitoring and audio management hub within the SLX-D+ digital wireless system for live sound, installed audio and professional production environments. Operating with 24-bit/48 kHz digital audio conversion and delivering a >118 dB dynamic range, the SLXD4D+ provides transparent audio reproduction alongside dependable RF performance across a 138 MHz wide tuning range (G57: 470–608 MHz), enabling reliable multi-system operation in congested RF conditions. Integrated ShowLink® Ease maintains continuous coordination between the receiver and linked SLX-D+ transmitters, allowing automatic frequency updates, interference mitigation, remote gain adjustment, transmitter locking, firmware updates and secondary transmitter linking without interrupting audio. The receiver supports Audio Summing, allowing both channels to function as a compact two-channel mixer when required, and system status can be monitored and controlled locally or remotely using Wireless Workbench desktop software or the WWB Mobile app over Ethernet, Wi-Fi or Bluetooth. Housed in a rugged metal chassis and supplied with rack-mount hardware, antennas and BNC cabling, the SLXD4D+—with balanced XLR and 1/4" outputs, AES-256 encryption and embedded Shure Digital Feedback Reducer processing—provides a scalable foundation for managing dual-channel SLX-D+ wireless microphone systems.
