Shure SLXD4D+ Duel Wireless Receiver

The Shure SLXD4D+ Dual Wireless Receiver is a robust, dual channel, half-rack system designed to deliver rock solid RF performance and pristine 24-bit digital audio in demanding live environments. With wide-tuning capability, ShowLink Ease remote control and powerful software integration, it gives engineers and tech teams precise, hands-free oversight of multiple wireless channels, all from a compact, tour-ready unit.

Engineered to be trusted by professionals yet accessible for volunteers and less experienced operators, the SLXD4D+ simplifies complex wireless management. Automatic setup, intelligent interference management and embedded digital feedback reduction work together to keep your mix clean and consistent, so you can focus on the performance rather than firefighting RF issues.

Transparent 24-bit Digital Audio

The SLXD4D+ delivers clear, detailed 24-bit digital audio with a dynamic range of more than 118 dB. This ensures vocals, speech and instruments are reproduced with exceptional clarity and headroom, helping your mix sit naturally without excessive EQ or gain adjustments.

Wide-tuning RF Performance

With a 138 MHz wide-tuning range, the SLXD4D+ offers greater geographical flexibility and easier frequency coordination. You can run up to 11 simultaneous systems in 6 MHz TV bands and up to 14 in 8 MHz TV bands, making it ideal for venues, touring rigs and multi-room installations that need reliable, scalable wireless coverage.

ShowLink Ease Remote Control

ShowLink Ease keeps SLXD+ transmitters and the SLXD4D+ receiver in constant communication, allowing you to adjust transmitter parameters over the air. Once an open frequency is identified, you can change the transmitter frequency, tweak RF power output, lock or unlock controls and even perform firmware updates, all without interrupting the performance.

Integrated Feedback Protection and Control Software

Patented Shure Digital Feedback Reducer is embedded in every SLX-D+ receiver, automatically reducing unwanted feedback should it occur. Combined with Wireless Workbench desktop software and the WWB Mobile app over Wi-Fi or Bluetooth, you can monitor RF status, scan for clear channels and manage receiver and transmitter settings from your laptop or mobile device.

• Dual Channel Half-rack Design - Two independent channels in a compact, rugged metal half-rack chassis let you manage multiple microphones or instruments from a single receiver, saving valuable rack space and simplifying cabling in mobile rigs, fixed installs and hire stock.
• 138 MHz Wide-tuning Range - The generous tuning bandwidth provides more available frequencies across different regions, making it easier to find clean spectrum and run up to 11 systems in 6 MHz TV bands or up to 14 systems in 8 MHz TV bands for larger setups.
• ShowLink Ease Over-the-air Control - Maintain control of your transmitters without leaving front of house. Adjust frequency, RF power and lock settings remotely, and perform firmware updates wirelessly, keeping your system optimised and responsive to changing RF conditions.
• Digital Feedback Reducer and AES-256 Encryption - Built-in Digital Feedback Reducer automatically tames problem frequencies before they become disruptive, while AES-256 encryption is installed on every SLX-D+ component to help keep your audio transmission secure and protected.
