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

Four-channel digital UHF wireless receiver for professional rack systems

The Shure SLXD4Q+ is a quad-channel digital wireless receiver built for small to medium venues, event spaces, conference rooms, houses of worship, and educational facilities. Four receiver channels are housed in a rugged 1U metal chassis, making the unit suitable for permanent installations and portable rack systems that require reliable multi-channel wireless audio.

The receiver operates across the G57 frequency range from 470 to 608 MHz, providing a wide 138 MHz tuning range and 5,520 selectable frequencies. It delivers transparent 24-bit digital audio with more than 118 dB of dynamic range, while Digital Predictive Switching Diversity helps maintain a dependable RF connection by selecting between its two removable antennas before a dropout occurs.

Each channel includes a balanced XLR mic or line output and a balanced 1/4-inch TRS output for connection to professional mixers and audio systems. Automatic frequency scanning and infrared synchronization simplify transmitter setup, while two RJ45 Ethernet ports support coordinated group scanning and remote control through Shure Wireless Workbench software.

Audio summing allows engineers to combine channels when fewer mixer inputs are available. Integrated RF cascade connections can link two SLX-D quad receivers to create an eight-channel wireless system occupying two rack spaces, with centralized monitoring and coordinated frequency management.

System Integration

The SLXD4Q+ integrates with compatible Shure SLX-D transmitters to create a scalable digital wireless system. Its discrete analog outputs connect directly to mixers, DSP platforms, and other professional audio equipment, while Ethernet networking enables remote receiver management through Wireless Workbench. TCP/IP command streams from third-party control systems, including AMX and Crestron, are also supported for integrated AV installations.

Broadcast Workflow Benefits

Placing four receiver channels in one rack space reduces equipment count and simplifies the wiring required for multi-channel wireless audio. Automatic scanning, infrared synchronization, front-panel RF and audio metering, remote software control, and adjustable gain help technicians configure and monitor multiple microphones efficiently during presentations, services, performances, and live events.

Frequently Asked Questions

How many wireless channels does the SLXD4Q+ support?

The receiver provides four independent digital wireless audio channels in a single 1U rackmount chassis.

What frequency range does this model use?

This G57 model operates from 470 to 608 MHz and provides a 138 MHz tuning range with 5,520 selectable frequencies.

Are transmitters or microphones included?

No. This listing includes the receiver and its supplied accessories, but transmitters and microphones are available separately.

Can the receiver be controlled over a network?

Yes. Two RJ45 Ethernet ports support coordinated scanning and remote management through Shure Wireless Workbench software.

Can two receivers be connected for additional channels?

Yes. RF cascade outputs allow two SLX-D quad receivers to be connected as an eight-channel system occupying two rack spaces.

Related Equipment and Workflow Compatibility

The SLXD4Q+ is compatible with Shure SLX-D transmitters and can be combined with additional SLX-D quad receivers for larger wireless deployments. Compatible transmitters are sold separately, allowing facilities to configure handheld, bodypack, or other SLX-D transmitter options for their specific application.

The receiver supports Shure UA874 active antennas and PA805SWB passive antennas. Its antenna bias voltage can power UA874 active directional antennas without separate power supplies, while the optional UA844+SWB antenna distribution system can support expanded multi-channel installations.
