The SLXD24+/B58 digital wireless handheld system combines the precision and presence of the Beta 58A supercardioid dynamic microphone with Shure's advanced SLXD+ digital wireless platform. Designed for professional vocal performance, houses of worship, corporate events, and live sound applications, it delivers pristine 24-bit digital audio with over 118 dB of dynamic range for clear, detailed, and powerful sound reproduction.
With a wide 138 MHz tuning range, the system ensures dependable RF stability across a variety of environments, supporting up to 11 simultaneous systems in 6 MHz TV bands and 14 in 8 MHz bands. Automatic Setup keeps transmitters and receivers locked in sync—even in challenging RF conditions—while Shure's patented Digital Feedback Reducer technology helps minimize unwanted feedback for confident live performance.
ShowLink Ease provides advanced remote management capabilities, allowing engineers to change transmitter frequency, adjust power levels, lock controls, and perform firmware updates over the air from the receiver. AES-256 encryption ensures secure wireless transmission, while integration with Wireless Workbench desktop software and the WWB Mobile app allows full monitoring and control via Wi-Fi or Bluetooth. Powered by two AA batteries or the optional Shure SB903 rechargeable battery, the SLXD24+/B58 delivers up to 8 hours of reliable operation with professional-grade durability.
