Shure SLXD4Q+TA Quad Wireless Rack Receiver (TAA - G57 (470-608 MHz)

The Shure SLXD4Q+TA Quad Digital Wireless Rack Receiver TAA Compliant is built for live sound, broadcast, installed audio, and houses of worship. Housed in a rugged full-rack metal chassis, it combines four receiver channels into a single unit, reducing cabling and simplifying multi-channel system deployment. This space-efficient design makes it ideal for high-channel-count setups while maintaining a clean and organized rack configuration.

High-Quality Audio and Wideband RF Performance

Built on the SLX-D+ platform, the SLXD4Q+ delivers transparent 24-bit digital audio with over 118 dB of dynamic range across all four channels. Its wide tuning range of up to 138 MHz (region dependent) enables simplified frequency coordination and reliable operation across various environments. The system supports up to 11 simultaneous channels per 6 MHz band and up to 14 per 8 MHz band, making it well suited for dense, large-scale wireless deployments.

Intelligent Wireless Management and System Control

The SLXD4Q+ features ShowLink Ease technology for real-time, two-way communication with compatible transmitters, ensuring automatic synchronization across frequency changes and power cycles. Engineers can remotely adjust transmitter settings, deploy clean frequencies when interference is detected, and perform firmware updates without direct access to the transmitters. Integration with Shure Wireless Workbench desktop software and the mobile app enables comprehensive monitoring and control via Wi-Fi or Bluetooth, while dual Ethernet ports support advanced networking and system expansion.

Advanced Features and Scalable System Integration

The receiver includes built-in Shure Digital Feedback Reduction (DFR) to automatically suppress feedback and enhance system stability across all channels. It supports a full range of SLX-D+ transmitters, including bodypack, handheld, and plug-on options with interchangeable microphone capsules. Additional features include quad-channel audio summing for flexible output routing and RF Cascade, allowing up to three units to link into a 12-channel system without extra accessories. With AES-256 encryption for secure transmission and a durable full-rack chassis, the SLXD4Q+ provides a powerful, scalable solution for professional wireless audio systems.
