Shure SLXD4Q+ Quad-Channel Digital Wireless Rackmount Receiver (TAA Compliant, G57: 470 to 608 MHz)

Four-channel SLX-D+ digital wireless receiver for professional rack systems

The Shure SLXD4Q+ is a professional quad-channel digital wireless receiver designed for live sound, installed audio, broadcast, and house of worship applications. Its full-rack, 1U chassis combines four receiver channels in one space-efficient unit, helping production teams build organized multichannel wireless systems with fewer individual receivers, cables, and rack accessories.

Operating in the G57 frequency range from 470 to 608 MHz, the receiver delivers transparent 24-bit digital audio with greater than 118 dB of dynamic range and a regionally dependent tuning range of up to 138 MHz. Each channel provides a balanced 3-pin XLR mic or line output and an unbalanced 1/4-inch output, while AES-256 encryption helps protect wireless audio transmission.

The SLXD4Q+ works with compatible SLX-D+ bodypack, handheld, and plug-on transmitters. Integrated ShowLink Ease technology supports two-way communication with compatible transmitters, enabling remote frequency changes, gain adjustments, control locking, interference response, synchronization, and over-the-air firmware updates without requiring physical access to each transmitter.

Wireless Workbench desktop software and the Wireless Workbench Mobile app provide system monitoring and configuration options for professional installations. Dual Ethernet connections support network integration, while RF Cascade allows as many as three SLXD4Q+ receivers to be linked into a 12-channel system without separate RF distribution accessories.

System Integration

The SLXD4Q+ provides a scalable foundation for Shure SLX-D+ wireless systems. It can receive signals from compatible SLXD1+ bodypack transmitters, SLXD2+ handheld transmitters, and SLXD3+ plug-on transmitters. Audio summing allows the receiver to provide streamlined output routing when required, while RF Cascade can connect up to three quad-channel receivers for a 12-channel deployment. Wireless Workbench integration, mobile monitoring, and dual Ethernet ports help engineers manage the receiver within larger networked wireless installations.

Broadcast Workflow Benefits

Combining four channels into one rack unit reduces the space, cabling, and accessory requirements associated with installing separate single-channel receivers. Remote transmitter management allows engineers to make frequency, gain, locking, and firmware changes from the receiver or connected software, which is especially valuable when transmitters are already placed on performers, presenters, or production personnel. Integrated Digital Feedback Reduction can also improve system stability in live environments with changing microphone positions and acoustic conditions.

Frequently Asked Questions
