Shure SLXD4Q+ Quad Wireless Receiver – 4-Channel G57 Digital Rack R...
The Shure SLXD4Q+ Quad Wireless Receiver in the G57 band is a powerful all-metal, single-rack unit designed for live sound, corporate AV, houses of worship, or any environment requiring multiple wireless channels with compact deployment. Built for use with Shure SLX-D transmitters, it delivers four discrete channels in one rack space, offering streamlined rack setups without sacrificing audio quality or RF performance.
With a wide tuning range of 138 MHz (G57 band: 470-608 MHz), it provides flexible frequency planning and helps avoid interference, especially in RF-crowded environments. The system features Digital Predictive Switching Diversity to maintain clean signal paths, reducing dropouts before they occur. The SLXD4Q+ offers 24-bit digital audio resolution with a dynamic range of around 118 dB, ensuring clean, transparent sound with low distortion.
Outputs include 4 XLRs plus 4 balanced 1/4-inch jacks, allowing direct feed to mixers, monitors, or other gear. There are also dual Ethernet ports for remote control and monitoring. Summing functionality allows for combining audio outputs to match available mixer inputs (4, 3, 2, or 1), simplifying smaller shows or constrained front-of-house racks. RF Cascading lets two units be paired to create up to an 8-channel system without needing extra accessories. The SLXD4Q+ is rugged, dependable, and engineered to be deployed from portable racks to fixed installs.
