Shure SLXD24+/B87A Digital Wireless Handheld Microphone System with Beta 87A Capsule (G57: 470 to 608 MHz)

The Shure SLXD24+/B87A is a professional 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 single-channel tabletop receiver in a rugged steel chassis—with rackmounting hardware included—along with a handheld microphone transmitter featuring a Beta 87A mic capsule.

Handheld Transmitter with Beta 87A Condenser Supercardioid Capsule
With durable aluminum housing, the SLXD2+ handheld transmitter offers a lightweight design that's comfortable to hold and features an LCD to show essential information. The Beta 87A condenser microphone capsule handles SPL levels up to 140 dB and offers a smooth frequency response with a gradual presence rise and controlled proximity effect tailored for vocals. Its supercardioid pickup pattern helps isolate the voice from unwanted background noise. 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 Beta 58A, SM58, 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).
