Shure SLXD2+/B58 Wireless Handheld Transmitter - G57 (470-608 MHz)

The Shure SLXD2+/B58 handheld transmitter, featuring the Beta 58C supercardioid dynamic microphone, unlock a new world of hands-free oversight and management for seasoned volunteers and pro engineers alike. Delivering wireless excellence, wherever required, wide-tuning SLXD+ transmitters and receivers stay in sync courtesy of a dedicated ShowLink Ease control link. Manage interference, scan for new channels and update for clear transmission automatically. Also monitor and configure via a paired mobile device.

Beta 58A Dynamic Supercardioid Capsule

The Beta 58A dynamic microphone capsule is designed for close-up vocals, with brightened midrange and bass roll-off to control proximity effect. The capsule features a supercardioid polar pattern that ensures high gain before feedback, maximum isolation from other sound sources, and minimum off-axis tone coloration.

Transparent Digital Audio and Expanded RF Performance

When paired with an SLX-D+ receiver, the SLXD2+ delivers transparent 24-bit digital audio with greater than 118 dB of dynamic range. A wide tuning bandwidth of up to 138 MHz (regionally dependent) supports flexible frequency coordination and reliable operation across a wide range of venues. The platform supports high channel counts in dense RF environments, making it suitable for scalable wireless deployments.

ShowLink Ease Remote Transmitter Control

ShowLink Ease enables real-time, two-way communication between the SLXD2+ transmitter and a compatible SLX-D+ receiver using BLE transmission. Once linked, the transmitter automatically follows receiver frequency changes across power cycles. Engineers can remotely adjust frequency, RF power, and control locks, apply interference mitigation, and perform over-air firmware updates without handling the microphone or requiring an IP network.

Interchangeable Capsule Design

The SLXD2+ features an interchangeable capsule design, allowing users to tailor the microphone to specific applications. In addition to the included Beta 58A, compatible Shure capsules include the Beta 87A, SM58, KSM8, Nexadyne 8/S, and Nexadyne 8/C, offering a range of pickup patterns and sonic characteristics.

Secure Operation and Flexible Power Options

The SLXD2+ supports AES-256 encryption for secure wireless transmission. It operates for up to 8 hours using two AA batteries, with support for optional Shure SB903 lithium-ion rechargeable batteries. When used with compatible Shure charging accessories (available separately), rechargeable batteries provide precise runtime readouts in hours and minutes directly on the transmitter display.
