The Shure SLXD4Q+ is a full-rack, four-channel digital wireless receiver designed to deliver professional-grade performance in a compact, space-saving format. Built for both experienced engineers and trained volunteers, it provides seamless hands-free oversight and system management while maintaining exceptional audio clarity and RF stability. As part of the SLX-D® Digital Wireless platform, it delivers transparent 24-bit digital audio with an impressive 118 dB dynamic range and rock-solid RF performance across a wide 138 MHz tuning range, enabling greater geographical coverage and flexible deployment.

The SLXD4Q+ supports up to 11 simultaneous systems in 6 MHz TV bands and up to 14 systems in 8 MHz bands, making it ideal for multi-channel installations. Once linked, SLX-D+ transmitters and receivers remain synchronized automatically, even in the presence of RF interference. With integrated ShowLink® Ease technology, users can remotely adjust transmitter parameters over the air directly from the receiver, including changing frequencies, adjusting power output, locking or unlocking controls, and performing firmware updates. Automatic setup and intelligent scanning simplify frequency coordination, while interference management ensures clear and stable transmission.

Advanced control and monitoring are available through Wireless Workbench desktop software or the WWB Mobile app via Wi-Fi or Bluetooth, providing real-time RF monitoring and parameter control. Shure’s patented Digital Feedback Reducer software is embedded in every SLX-D+ receiver to automatically reduce unwanted feedback if it occurs. AES-256 encryption comes installed as standard, ensuring secure wireless transmission for sensitive applications.

Designed for efficiency and scalability, the SLXD4Q+ offers audio summing to match available mixer channels (4, 3, 2, or 1), four XLR and four ¼-inch outputs, and dual Ethernet ports for network integration. RF Cascade functionality allows three SLXD4Q+ units to be linked into a 12-channel system without additional accessories. Featuring bias voltage power supply management, digital predictive switching diversity, and rugged metal construction, the SLXD4Q+ delivers reliable, secure, and scalable wireless excellence for professional sound reinforcement environments.
