Shure ULXD4Q Quad-Channel Digital Wireless Receiver with Dante and AES-256 Encryption
The Shure ULXD4Q is a high-performance quad-channel digital wireless receiver designed for demanding professional audio environments. Housed in a rugged single-rack unit, this receiver integrates four independent digital channels, Dante™ audio networking, and RF cascade capabilities—making it a scalable solution for large-scale systems and AV installations.
Part of the renowned ULX-D wireless series, the ULXD4Q delivers pristine 24-bit/48 kHz digital audio, capturing every vocal nuance and instrumental detail with exceptional accuracy and clarity. Its audio summing feature allows the unit to function as a four-channel mixer, further streamlining your rack setup.
Ideal for live sound venues, houses of worship, corporate AV, conferences, and educational facilities, the ULXD4Q simplifies wireless coordination across large systems. It operates in the UHF band using Digital Predictive Switching Diversity to ensure rock-solid RF stability and resistance to interference, even in crowded frequency environments.
Two operational modes offer flexible performance:
Standard Mode: Run up to 17 channels per 6 MHz TV band with a range up to 330 feet
High-Density Mode: Maximize spectrum efficiency with up to 47 channels per 6 MHz TV band at a range of up to 98 feet
The system includes AES-256 encryption for secure transmission of sensitive audio, ensuring privacy for corporate, government, or high-profile events.
Each of the four receiver modules includes dedicated RF and audio meters, 60 dB of gain control, and balanced XLR outputs. A large front-panel LCD screen and intuitive controls provide quick access to essential settings—even in dark environments. Key features include IR sync, automatic frequency scanning, input gain optimization, and internal limiting to prevent clipping.
The dual Ethernet ports support Dante audio routing and enable easy network integration for large installations using Shure Wireless Workbench® software or ShurePlus™ Channels iOS app for remote monitoring and control.
