Shure SLXD4D+ Dual Channel Digital Wireless Receiver - G57 (470 to 608 MHz)

Professional dual-channel digital wireless receiver with 24-bit audio, ShowLink Ease remote control, and AES-256 encryption for live events and houses of worship.

The Shure SLXD4D+ Dual-Channel Wireless Receiver is a professional dual-channel digital wireless receiver delivering transparent 24-bit audio with over 118 dB of dynamic range for live event production and houses of worship. ShowLink Ease enables over-the-air control of linked SLX-D+ transmitters directly from the receiver, allowing frequency changes, output power adjustments, control locks, and firmware updates without physically handling the transmitter. A wide 138 MHz tuning range across the 470 to 608 MHz UHF band supports up to 14 simultaneous systems in 8 MHz TV bands, providing the RF headroom that multi-channel live event productions and touring rigs demand. Advanced monitoring through Wireless Workbench desktop software and the WWB Mobile app over Wi-Fi or Bluetooth gives engineers full visibility into RF status and transmitter parameters from anywhere in the venue. With AES-256 encryption installed on every SLX-D+ component, Automatic Setup for persistent transmitter-receiver linking and Shure's patented Digital Feedback Reducer embedded in the receiver, the Shure SLXD4D+ Dual-Channel Wireless Receiver delivers secure, interference-resistant wireless performance built for demanding installations.

Dual-Channel RF Performance and 138 MHz Tuning Range

The Shure SLXD4D+ operates across the 470 to 608 MHz UHF frequency band with a 138 MHz wide-tuning range, offering 5,520 selectable channel frequencies. The dual-channel half-rack design supports two independent audio channels with balanced XLR and unbalanced 1/4-inch outputs per channel. Automatic Setup keeps SLX-D+ transmitters and receivers linked through RF interference, eliminating the need for manual re-pairing during shows. The system supports up to 14 simultaneous channels in 8 MHz TV bands and up to 11 in 6 MHz bands, giving live event production teams and houses of worship the scalability to expand wireless coverage as needs grow.

ShowLink Ease Remote Transmitter Control

ShowLink Ease allows engineers to adjust linked SLX-D+ transmitter parameters over the air directly from the SLXD4D+ receiver. Available adjustments include transmitter frequency changes, output power level, control lock and unlock, and firmware updates. For managing equipment from a booth or houses of worship where transmitters are distributed across a stage, ShowLink Ease eliminates the need to interrupt a performance to make critical wireless adjustments.

Wireless Workbench Software and WWB Mobile Monitoring

The SLXD4D+ integrates with Shure Wireless Workbench desktop software for comprehensive RF monitoring, frequency coordination, and system configuration. Remote monitoring is also available through the WWB Mobile app over Wi-Fi or Bluetooth, allowing engineers to check RF status and control receiver and transmitter parameters from anywhere in the venue. An RJ45 network connection on the rear panel enables wired integration into larger networked audio systems. For live event production teams managing multiple wireless channels across a venue, this level of remote visibility reduces troubleshooting time and keeps shows running smoothly.

Digital Feedback Reducer

Shure's patented Digital Feedback Reducer software is embedded in the SLXD4D+ receiver, automatically detecting and suppressing unwanted audio feedback before it becomes audible. The system operates transparently without user intervention, maintaining natural audio quality while protecting against feedback events. Houses of worship with volunteer-run sound teams benefit from this hands-free feedback management, reducing the technical expertise required to maintain clean audio during services.

AES-256 Encryption and Build Quality

Every SLX-D+ component and system ships with AES-256 encryption installed, securing the wireless audio signal against interception. The SLXD4D+ features rugged metal construction in a half-rack form factor, rack-mountable with included hardware in a single rack unit. At 2 pounds without antennas, the receiver is lightweight enough for rigs that travel between venues while remaining durable enough for permanent installation in houses of worship and production facilities.
