The Shure ULXD4Q Quad Channel Digital Wireless Receiver packs four independent receivers into a single rack unit, offering professional sound reinforcement applications an intelligent solution that maximises both space and performance. This rugged yet lightweight 1RU all-metal chassis weighs just 7.6 pounds and features Digital Predictive Switching Diversity, a 64 MHz tuning range, and AES 256 encryption for enhanced security. Each of the four channels operates independently with its own audio and RF meters, gain control, and XLR outputs that can be configured for direct or summed signal routing.
The ULXD4Q provides significant advantages for touring and installation applications through its space-efficient design and advanced networking capabilities. RF cascade functionality and dual Ethernet ports allow multiple units to share RF signals and connect seamlessly for simplified frequency coordination and deployment. For networked audio setups, Dante™ digital networking enables multiple audio channels to run over a single Ethernet cable, streamlining system integration.
As part of the ULX-D® Digital Wireless Systems range, the ULXD4Q represents a substantial advancement in receiver technology for its class, bringing professional-grade performance and scalability to sound reinforcement applications. The combination of uncompromising audio quality, RF signal stability, and advanced setup features makes this quad receiver a compelling choice for professionals seeking reliable wireless solutions. Please ensure frequency bands match when purchasing separate wireless components to guarantee proper system operation.
