The Shure SLXD4+ digital wireless receiver is a single-channel, half-rack receiver designed to function as a stable control and monitoring 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 SLXD4+ provides transparent audio reproduction alongside dependable RF performance across a 138 MHz wide tuning range (G57: 470–608 MHz), supporting reliable multi-system deployment in congested RF conditions. Integrated ShowLink® Ease enables 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 operation. System status and parameters can be monitored and managed locally or remotely using Wireless Workbench desktop software or the WWB Mobile app over Ethernet, Wi-Fi or Bluetooth, while embedded Shure Digital Feedback Reducer processing provides automatic feedback control at the receiver level. Housed in a rugged metal chassis with balanced XLR and 1/4" outputs, AES-256 encryption and network connectivity for system integration, the SLXD4+ serves as a reliable foundation for building and managing single-channel SLX-D+ wireless microphone systems.
