Shure SLXD24D+/B58-G57 Description

The SLXD24D+/B58-G57 is ideal for professional stages, houses of worship, and corporate AV setups where clean vocal performance and interference-free operation are critical. The included Beta 58A capsules provide high gain-before-feedback and a brightened presence peak—tailored for cutting through the mix while rejecting background noise. With the dual-channel SLXD4D+ receiver, both transmitters can operate independently and be managed from a single unit. Setup is fast and reliable, thanks to automatic channel syncing and wide 138 MHz tuning range. Once connected, ShowLink® enables real-time changes to transmitter settings such as frequency, gain, and control locks—without touching the mics. AES-256 encryption ensures signal security, while patented Digital Feedback Reducer technology helps maintain clean sound. The system runs up to 8 hours on AA batteries or optional Shure SB903 rechargeable batteries for added flexibility.
