The Shure SLXD4+ is a professional single-channel digital wireless receiver designed for live sound, installed audio, broadcast, and house of worship applications. Built on the SLX-D+ platform, it delivers transparent digital audio, expanded wideband RF performance, and advanced hands-free wireless management tools for reliable operation in demanding environments. The SLXD4+ features a rugged half-rack metal chassis with balanced XLR and 1/4” output connections, and removable antennas.

Transparent Digital Audio and Wideband RF Performance
The SLXD4+ delivers clear, accurate 24-bit digital audio with greater than 118 dB of dynamic range. A wide tuning range of up to 138 MHz (regionally dependent) provides broad geographical coverage and simplified frequency coordination. The receiver supports up to 11 simultaneous systems per 6 MHz TV band and up to 14 systems per 8 MHz TV band, making it well suited for scalable multi-channel deployments.

ShowLink Ease Automated Wireless Management
Integrated ShowLink Ease technology enables two-way communication between the SLXD4+ receiver and compatible SLX-D+ transmitters. Once linked, transmitters automatically stay in sync with the receiver across power cycles and RF changes. Engineers can remotely change transmitter frequency, adjust gain, lock or unlock controls, deploy new clean frequencies when interference is detected, link a second transmitter to the same receiver channel, and perform over-the-air firmware updates—without physically accessing the transmitter.

Wireless Workbench Desktop and Mobile Control
The SLXD4+ integrates seamlessly with Shure Wireless Workbench desktop software and the Wireless Workbench Mobile app. Users can monitor RF performance, configure system parameters, manage transmitters via ShowLink Ease, and perform interference monitoring over Wi-Fi or Bluetooth. A high-contrast, backlit LCD screen on the receiver's front panel provides clear visibility of essential system status information for quick setup and monitoring in low-light environments.

Integrated Digital Feedback Reduction
Patented Shure Digital Feedback Reduction (DFR) software is embedded directly into the SLXD4+ receiver. DFR automatically detects and suppresses feedback using dynamic notch filtering, improving clarity and system stability in live sound environments where acoustics and microphone placement may be unpredictable.

Multiple Transmitter Options
Shure offers numerous SLX-D+ transmitter choices, depending on your needs and preferences. For a discreet hands-free option, the SLXD1+ bodypack features a lightweight and ergonomic ABS chassis with a TA4M input connector that can accommodate a wide variety of lavalier and headset microphones, as well as instrument cables for guitar and bass players. For presenters and performers looking for a handheld option, the SLXD2+ offers a durable aluminum housing and an interchangeable capsule design. Available microphone capsules include the SM58, Beta 58A, Beta 87A, KSM8, Nexadyne 8/C, and Nexadyne 8/S. Rounding out the lineup, SLXD3+ plug-on transmitter allows you to use any XLR microphone and features phantom power for condensers.

Secure and Rugged System Design
Each SLX-D+ receiver ships with AES-256 encryption enabled for secure wireless transmission. The SLXD4+ features a rugged metal half-rack chassis—a rackmounting kit is included—designed for reliable operation in touring, installed, and broadcast environments, providing a stable foundation for professional wireless audio systems
