Shure SLXD24+/B87A S50 Digital Wireless System

Professional Digital Wireless Audio Performance!

The Shure SLX-D+ series represents cutting-edge digital wireless audio technology with crystal-clear 24-bit signal quality, extremely robust RF transmission and intelligent remote control — ideal for live stages, presentations, conferences, broadcast productions and installations of any scale. Built for maximum reliability, it offers extended tuning bandwidth, automatic link management, remote-control features and secure data transmission for professional users.

SLXD2+ Handheld Transmitter with Beta 87A Capsule

The Shure SLXD2+/B87A is a professional digital handheld transmitter with an integrated Beta 87A condenser capsule, engineered for demanding live vocals, theatre productions, conferences and worship applications. The supercardioid pattern delivers precise directionality with high feedback rejection and excellent suppression of stage and ambient noise, while the condenser design provides exceptionally detailed, transparent and present vocal reproduction. Paired with the SLX-D+ platform, you benefit from 24-bit digital audio with >118 dB dynamic range, 2.8 ms latency and a 138 MHz tuning bandwidth for stable RF performance. With ShowLink Ease you can remotely adjust frequency, output level, mute functions and perform firmware updates from the paired receiver, while integrated AES 256-bit encryption ensures top-level data security. Power is supplied by two AA batteries for up to 8 hours of runtime or optionally by the rechargeable Shure SB903 lithium-ion battery.

SLXD4+ Receiver

The Shure SLXD4+ is a professional 1-channel digital receiver in a half-19" format and serves as the central controller within SLX-D+ wireless systems for stage, theatre, conference rooms and installations. It handles 24-bit digital audio with a dynamic range of >118 dB and a system latency of 2.8 ms, ensuring transparent, distortion-free signal transmission at the highest technical level. With an extended 138 MHz tuning bandwidth, the SLXD4+ enables flexible frequency coordination and parallel operation of multiple compatible systems per TV band. The integrated ShowLink Ease control link allows remote adjustment of transmitter parameters such as frequency, output level, mute and firmware updates directly from the receiver. Additionally, the built-in Shure Digital Feedback Reducer software provides automatic feedback suppression, while factory-installed AES 256-bit encryption guarantees maximum data security. The receiver can be fully integrated into network environments via Ethernet and used with Wireless Workbench for professional RF monitoring and system management.

The SLXD1+ Family

Digital Sound Quality & Low Latency

The SLX-D+ series delivers transparent 24-bit digital audio quality with a very high dynamic range of over 118 dB and extremely low latency, resulting in clear, lifelike and highly detailed sound reproduction. This technology is equally suited to speech, vocals or instrument capture in demanding environments where the highest audio fidelity is required.

Extended RF Bandwidth & Stable Wireless Link

With a tuning bandwidth of up to 138 MHz (region-dependent), the SLX-D+ series offers unusually large frequency flexibility. This enables wider geographic coverage and supports many simultaneously usable systems across different TV bands. The robust RF performance ensures stable and interference-resistant wireless links even in complex RF environments with high system density.

Intelligent Automatic Setup

Once paired, receiver and transmitter stay reliably connected even in the presence of RF interference. Automatic setup and synchronization simplify everyday use — especially where fast, reliable setups are needed. The system detects free frequencies, updates channels automatically and optimizes the link, minimizing error sources and reducing setup time.

ShowLink Ease Remote Management & Control

The integrated ShowLink Ease control link lets you remotely manage and monitor transmitter parameters directly from the receiver. You can adjust frequencies, control levels, lock or unlock transmitters and even perform firmware updates — all remotely, without direct access to individual components. The series also integrates with Shure Wireless Workbench software and the WWB Mobile app for comprehensive RF management and monitoring.

Automatic Feedback Reduction & Security

The patented Digital Feedback Reducer software is built into every SLX-D+ receiver and automatically detects and reduces unwanted feedback. In addition, all systems come standard with AES 256-bit encryption — an important security feature for confidential events such as business or government functions.

Flexible Runtime & Mobility

The series is designed for long deployments: up to around 8 hours of runtime is possible with two AA batteries; longer operation is available with optional rechargeable Shure SB903 lithium-ion batteries and compatible charging accessories. Mobile components are ideal for camera hot-shoe mounting or sound bags, while rack-mountable systems support professional installations.
