Shure SLXD24D+/N8C – Dual Wireless Handheld System with Nexadyne™ 8/C for Crystal-Clear Live Audio.

The Shure SLXD24D+/N8C Dual Wireless Handheld System pairs two Nexadyne™ 8/C cardioid dynamic microphones with the advanced SLX-D+ digital wireless platform, offering a complete dual-channel solution for professional vocal applications.

Ideal for live performances, conferences, houses of worship, and touring productions, this system provides transparent 24-bit digital audio with >118 dB dynamic range, robust RF coverage, and remote management via ShowLink® Ease. The dual-channel SLXD4D+ half-rack receiver integrates seamlessly with two SLXD2+ handheld transmitters, supporting wide-tuning operation across a 138 MHz range.

Automatic Setup ensures stable connections even in RF-heavy environments, while ShowLink® Ease allows remote transmitter control for gain, frequency, locking, firmware updates, and real-time monitoring through Shure Wireless Workbench desktop software or the WWB Mobile app.

• For the CH70 variant: This frequency band (823–865 MHz) is license-free in the UK, perfect for straightforward setup without additional licensing requirements.

SLX-D+ vs SLX-D – What’s New?

Shure’s SLX-D+ Wireless Microphone Systems take everything that made SLX-D a trusted professional solution and make it even better. While the audio quality remains the same crystal-clear 24-bit digital sound you expect, SLX-D+ adds enhanced features for easier setup, more reliable performance, and greater flexibility across a wide range of venues.

Key Improvements in SLX-D+:

• Expanded Wide Tuning Range: 138 MHz coverage on all components gives you more flexibility to operate in different regions and crowded RF environments.
• ShowLink® Ease: Adjust transmitter settings remotely from the receiver, including gain control, firmware updates, and automatic frequency scanning — all without touching the transmitter.
• Digital Feedback Reduction (DFR): Shure’s patented DSP automatically suppresses unwanted feedback, ensuring smooth and uninterrupted audio.
• AES-256 Encryption: Each component includes advanced encryption for secure and private wireless transmission.
• Lower Latency: Improved 2.8 ms latency ensures audio remains perfectly in sync with live performance or presentations.
• Bluetooth & Wireless Monitoring: Track and manage system status via Wireless Workbench and mobile apps from iOS or Android devices.
• Flexible System Configurations: Choose from portable, ½ rack, or full rack quad receivers, plus bodypack, handheld, and plug-on transmitters for any scenario.
• Reliable Power Options: Use standard AA batteries for up to 8 hours, or Shure’s SB903 Li-ion rechargeable batteries for convenient charging solutions.

SLX-D+ is ideal for professional engineers, volunteers, and performers who want the simplicity and reliability of SLX-D, but with automated setup, smarter monitoring, and additional security. Whether you’re on stage, in a lecture hall, a place of worship, or managing a complex multi-channel installation, SLX-D+ makes wireless audio easier, faster, and more dependable.
