The SLXD+ Series

Digital Audio 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, providing clear, natural and highly detailed sound reproduction. This technology is equally suited for speech, vocals or instrument transmission under demanding conditions where the highest 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 greater geographic coverage and supports many simultaneously usable systems across different TV bands. The robust RF performance ensures stable, low-interference wireless links even in complex RF environments with high system density.

Intelligent Automatic Setup

Once paired, receivers and transmitters remain reliably connected even in the presence of RF interference. Automatic setup and synchronization simplify everyday use — especially where fast, dependable setups are required. The system detects free frequencies, updates channels automatically and optimizes the link, reducing error sources and setup time.

ShowLink Ease Remote Management & Control

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

Automatic Feedback Reduction & Security

The patented digital Feedback Reducer software is integrated into every SLX-D+ receiver and automatically detects and reduces unwanted feedback. Additionally, all systems come standard with AES-256 encryption — an important security feature for confidential content such as corporate or government events.

Flexible Runtime & Mobility

The series is built for long deployments: up to approximately 8 hours of runtime is possible with two AA batteries; longer operation is also supported 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.
