Shure SLXD2+/B58 Digital Wireless Handheld Transmitter with Beta 58A (G57 Band)

The Shure SLXD2+/B58 handheld transmitter pairs Shure’s SLX-D+ digital wireless platform with the Beta 58A dynamic supercardioid microphone cartridge for reliable, high-quality vocal performance in live sound, installed sound, and house of worship environments. Built for everyday stage use, it delivers consistent wireless operation with a rugged metal design.

SLX-D+ expands on the SLX-D system with a wide tuning range (region-dependent) and a dedicated ShowLink® Ease control link for remote transmitter management. When used with compatible SLX-D+ receivers, the system can automatically address interference, scan for clear channels, and keep transmitters and receivers connected for stable operation.

Bluetooth® monitoring and control, AES-256 encryption, and professional-grade 24-bit / 48 kHz audio conversion make the SLXD2+/B58 a strong fit for venues that need dependable RF performance, clear vocals, and secure wireless workflow.
