SHURE SLXD24D+/N8C | Dual-channel Digital Wireless Microphone System W/ Nexadyne 8c

SLXD24D+/N8C

Dual-Channel Digital Wireless Handheld Microphone System with Nexadyne 8/C Cardioid Capsule (G57: 470 to 608 MHz)

The SLXD24D+/N8C is a professional dual-channel digital wireless handheld microphone system designed for live performance, installed sound, and houses of worship. Built on the SLX-D+ platform, it combines transparent digital audio with expanded frequency coverage, automated wireless management, and hands-free system control for confident operation in demanding RF environments. This configuration includes a two-channel tabletop receiver in a rugged steel half-rack chassis—with rackmounting hardware included—along with two handheld microphone transmitters, each featuring a Nexadyne 8/C mic capsule.

Two Handheld Transmitters with Nexadyne 8/C Cardioid Revonic Capsules

With durable aluminum housing, each of the SLXD2+ handheld transmitters offers a lightweight design that's comfortable to hold and features an LCD to show essential information. The microphone capsule features Shure's Nexadyne Revonic system, an innovative dynamic microphone design that uses two matched dynamic transducers, working in conjunction, to provide more opportunity for both greater sound quality and the rejection of unwanted signal.

Wiring the transducers out-of-phase cancels mechanical vibration, so self-noise is actively zeroed out. This makes traditional pneumatic shockmounts unnecessary, and allows the transducers to be optimized for acoustic performance. Vocal performers will experience natural and vivid clarity when performing—enabled by a cartridge design that optimizes signal output acoustically, producing more of the desired sound source and less environmental and handling noise.

Engineers will receive stronger and clearer output, resulting in fewer EQ corrections that are often necessary with other mics to retain vocal clarity within the mix. The cardioid polar pattern provides focused, yet forgiving, audio capture centered on the performer in front of the mic—reducing bleed from other sources and on-stage monitors for clearer sound.

The transmitter's interchangeable capsule design allows you to choose the ideal capsule for your application. Shure offers a variety of optional dynamic and condenser mic capsules with varying pickup patterns—capsules include the Nexadyne 8/S (supercardioid), SM58, Beta 58A, Beta 87A, and KSM8.

Transparent Digital Audio and Expanded RF Performance

SLX-D+ delivers transparent 24-bit digital audio with greater than 118 dB of dynamic range for clear, accurate sound reproduction. An expanded wide tuning frequency range of up to 138 MHz (regionally dependent) provides greater geographical coverage and simplified frequency coordination. The system 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

ShowLink Ease provides real-time two-way communication between paired SLX-D+ receivers and transmitters using BLE transmission. Once linked, transmitters automatically follow receivers across power cycles and RF changes. Engineers can remotely change transmitter frequency, adjust RF power, lock or unlock controls, apply interference mitigation, and perform over-air firmware updates—without touching the transmitter or requiring an IP network.

Wireless Workbench Desktop and Mobile Control

SLX-D+ systems integrate with Shure Wireless Workbench desktop software and the Wireless Workbench Mobile app, enabling monitoring and control over Wi-Fi or Bluetooth. Multiple mobile devices can associate with SLX-D+ receivers, with primary and backup control support. System setup, group scanning, transmitter management via ShowLink Ease, and interference monitoring can all be handled from a centralized interface.

Integrated Digital Feedback Reduction

Patented Shure Digital Feedback Reduction (DFR) software automatically detects and suppresses audio feedback using dynamic notch filters. Integrated directly into the SLX-D+ platform, DFR enhances clarity and stability in live sound environments where microphone placement and room acoustics may be less predictable.

Secure Operation and Flexible Power Options

SLX-D+ systems feature AES-256 encryption for secure wireless transmission. The bodypack transmitter operates for up to 8 hours on two AA batteries, with optional SB903 lithium-ion rechargeable batteries providing precise runtime readouts in hours and minutes when used with compatible Shure charging accessories (available separately).
