Description
The Shure SLXD4Q+ Quad-Channel Digital Wireless Receiver delivers high-performance, scalable wireless audio in a full-rack format designed for professional environments. Built on the SLX-D+ platform, this receiver combines four independent channels into a single rack space, streamlining deployment while reducing cabling and hardware requirements.
Engineered for live sound, broadcast, installed AV systems, and houses of worship, the SLXD4Q+ provides pristine 24-bit digital audio with over 118 dB of dynamic range. Its wide 138 MHz tuning range ensures flexible frequency coordination across regions, while support for high channel density allows multiple systems to operate reliably in crowded RF environments.
With ShowLink Ease technology, users benefit from seamless two-way communication between receiver and transmitters, enabling automatic synchronization, remote adjustments, and real-time frequency management without physical access. Integration with Wireless Workbench software and mobile control apps further enhances monitoring, configuration, and system optimization.
Built-in Digital Feedback Reduction enhances clarity and stability by automatically detecting and suppressing feedback. AES-256 encryption ensures secure wireless transmission, while RF cascade and audio summing capabilities allow for easy system expansion and simplified signal routing.
Housed in a rugged steel chassis and designed for reliability in demanding environments, the SLXD4Q+ is a powerful, flexible solution for multi-channel wireless audio systems.
