Description
Professional single-channel digital wireless receiver with 24-bit audio, ShowLink Ease remote control, and AES-256 encryption for live events, houses of worship, and mobile DJ applications.
The Shure SLXD4+ Single-Channel Wireless Receiver is a professional single-channel digital wireless receiver delivering transparent 24-bit audio with over 118 dB of dynamic range for live event production, houses of worship, and mobile DJ applications. ShowLink Ease enables over-the-air control of linked SLX-D+ transmitters directly from the receiver, allowing frequency changes, 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 scalability that growing wireless installations and touring rigs demand. 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 SLXD4+ Single-Channel Wireless Receiver delivers secure, interference-resistant wireless performance in a compact half-rack form factor.
Single-Channel RF Performance and 138 MHz Tuning Range
The Shure SLXD4+ operates across the 470 to 608 MHz UHF frequency band with a 138 MHz wide-tuning range, offering 5,520 selectable channel frequencies. The single-channel half-rack design delivers one audio channel with balanced XLR and unbalanced 1/4-inch outputs, and two units can be paired side by side in a single rack unit for multi-channel deployments. Automatic Setup keeps SLX-D+ transmitters and receivers linked through RF interference, eliminating 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 houses of worship and live event production teams the flexibility to scale wireless channel counts 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 SLXD4+ receiver. Available adjustments include transmitter frequency, output power level, control lock and unlock, and firmware updates. For mobile DJs managing a single wireless channel from a booth or houses of worship where a pastor's transmitter is positioned on stage, ShowLink Ease eliminates the need to interrupt a service or performance to make critical wireless adjustments.
Wireless Workbench Software and WWB Mobile Monitoring
The SLXD4+ 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, giving engineers visibility into RF status 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 building out multi-receiver racks one channel at a time, this remote visibility simplifies system management and reduces troubleshooting time.
Digital Feedback Reducer
Shure's patented Digital Feedback Reducer software is embedded in the SLXD4+ 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 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 SLXD4+ features rugged metal construction in a half-rack form factor, rack-mountable with included hardware in a single rack unit alongside a second half-rack device. At 2 pounds without antennas, the receiver is lightweight enough for mobile DJ rigs traveling between gigs while remaining durable enough for permanent installation in houses of worship and production facilities.
