Shure SLXD2+ Wireless SM56 Handheld Transmitter

The Shure SLXD2P-SM86-K55 is a robust digital wireless handheld transmitter paired with the acclaimed SM86 cardioid condenser capsule. Designed for vocalists, presenters and engineers who demand clarity and control, it delivers transparent 24-bit audio, rock-solid RF performance and effortless integration into modern, networked setups.

Part of the SLX-D+ family, this handheld transmitter is built to keep your show running smoothly. Wide 138 MHz tuning and automatic setup help you find clean frequencies quickly, while ShowLink Ease lets you adjust key transmitter parameters remotely from the linked receiver. Whether you are running a busy stage, a house of worship or a corporate event, you get reliable, great-sounding wireless that is simple to deploy and manage.

SM86 Condenser Capsule

The SLXD2+ handheld comes fitted with Shure’s SM86 cardioid condenser microphone, a live sound staple known for its clear, detailed vocal reproduction. The tailored frequency response is optimised for speech and singing, helping voices sit naturally in the mix without excessive EQ. Its cardioid pickup pattern focuses on the performer and reduces unwanted spill from stage monitors and nearby sources, giving you more gain before feedback in challenging environments.

24-bit Digital Audio and Wide Dynamic Range

With 24-bit digital audio and more than 118 dB of dynamic range, the SLXD2+ transmitter captures every nuance of a performance. Quiet passages remain clean and free from noise, while loud peaks are handled effortlessly without harshness or distortion. This gives engineers more headroom to work with and ensures consistent, studio-like sound quality on stage or in the conference room.

ShowLink Ease Remote Control

ShowLink Ease unlocks over-the-air control of the transmitter from the linked SLX-D+ receiver. Once connected, you can change the transmitter frequency when a clearer channel is found, adjust RF power output, lock or unlock the controls and even perform firmware updates without touching the microphone. This hands-free oversight is ideal for multi-mic productions where quick, discreet adjustments are essential.

Rugged, Practical and Secure

Built with a metal housing, the SLXD2+ transmitter is ready for the demands of touring, installations and regular live use. Power options include standard AA batteries or optional Shure SB903 rechargeable batteries, delivering up to 8 hours of runtime. Every SLX-D+ component ships with AES-256 encryption enabled, helping to keep your audio transmission secure in environments where privacy and data protection are a priority.

• SM86 Cardioid Condenser Microphone - The integrated SM86 capsule delivers crisp, articulate vocals with a tailored frequency response that flatters speech and singing. Its cardioid pattern helps reject off-axis noise, improving clarity and feedback resistance on loud stages and in reflective rooms.
• 24-bit Digital Audio with >118 dB Dynamic Range - High-resolution digital transmission preserves the full detail and dynamics of your performance. From quiet spoken word to powerful lead vocals, you get consistent, low-noise sound that sits easily in any professional mix.
• Wide 138 MHz Tuning and Automatic Setup - A generous tuning range allows the system to operate reliably across more locations, with support for multiple simultaneous systems within standard TV bands. Automatic setup and linking keep transmitters and receivers connected, even as RF conditions change.
• ShowLink Ease and Remote Management - Adjust transmitter settings wirelessly from the paired receiver, and monitor system status via Wireless Workbench software or the WWB Mobile app over Wi-Fi or Bluetooth. This centralised control saves time, reduces on-stage interruptions and helps engineers respond quickly to interference or configuration changes.
