The SLXD2+/B58 is a digital wireless handheld transmitter featuring the Beta® 58A supercardioid dynamic capsule, combining a tighter pickup pattern and higher output with the intelligent wireless management of the SLX-D+ platform. It suits demanding live vocals where maximum feedback rejection is essential.

Beta® 58A Supercardioid Capsule

The Beta 58A supercardioid dynamic capsule delivers a brighter, more detailed sound than standard cardioid dynamic capsules, with a tighter pickup pattern that significantly reduces off-axis bleed and feedback susceptibility on loud stages.

24-Bit Digital Audio

Transparent 24-bit digital audio with over 118 dB dynamic range captures every nuance of the vocal without compression, preserving the Beta 58A's extended frequency response in the wireless chain.

Wide-Tuning RF & Automatic Setup

The 138 MHz wide-tuning range and Automatic Setup maintain a stable RF link regardless of interference, supporting up to 14 simultaneous systems in a single venue.

ShowLink® Ease & Remote Management

Transmitter gain, frequency, and output power are adjustable over the air from the linked receiver via ShowLink® Ease, with full monitoring available through Wireless Workbench or the WWB Mobile app.

AES-256 Encryption & Battery

AES-256 encryption is active on every unit for complete transmission security. Up to 8 hours of runtime from 2 AA batteries or the optional Shure SB903 Li-ion rechargeable battery.
