The Shure ULXD4Q is a professional quad-channel digital wireless receiver, representing a high-density solution within the ULX-D series, engineered to deliver pristine audio quality, maximum RF stability, and comprehensive system control for large-scale wireless applications. Housed in a compact 1U rack-mountable chassis, it contains four fully independent digital receivers, dramatically optimizing rack space and simplifying cabling for installations requiring many channels, such as major concert tours, broadcast studios, large houses of worship, and corporate events. Operating in license-free frequency bands (such as the 2.4 GHz ISM band in many regions), it utilizes advanced digital transmission to provide crystal-clear audio with ultra-low latency and robust immunity to RF interference.

A defining strength of the ULXD4Q is its deep integration with Shure's control and monitoring ecosystem. Via a single Ethernet connection, it enables remote frequency coordination, real-time monitoring of RF and audio parameters for all four channels, and detailed transmitter battery status reporting through Shure Wireless Workbench software. The front-panel color LCD screen provides immediate access to settings and status for each channel. The receiver offers flexible audio connectivity, including analog XLR outputs for each channel and a digital Dante audio-over-IP output that carries all four channels on a single network cable, enabling seamless integration into modern networked audio systems. Advanced features like automatic gain adjustment, encryption, and compatibility with Shure's rechargeable battery system streamline professional workflows.

Built for reliability in the most demanding environments, the Shure ULXD4Q sets a benchmark for density and performance in digital wireless. It provides audio engineers with unparalleled channel count, control, and sonic fidelity in a minimal footprint, making it an ideal choice for applications where rack space is at a premium and flawless wireless performance is non-negotiable. By combining premium digital audio, intelligent networking, and robust RF performance in a quad-channel design, it offers a future-proof and highly scalable solution for critical wireless audio channels.
