The SLXD24D+/B58 dual wireless system combines two SLXD2+/B58 handheld transmitters featuring the renowned Beta 58A supercardioid dynamic microphones with the half-rack SLXD4D+ dual-channel receiver. Designed for live performance, houses of worship, corporate events, and broadcast applications, the system delivers transparent 24-bit digital audio with over 118 dB of dynamic range and consistent, interference-free operation.
With a wide 138 MHz tuning range, the SLX-D+ platform supports up to 11 simultaneous systems in 6 MHz TV bands and up to 14 systems in 8 MHz bands, providing flexible frequency coordination in complex RF environments. Automatic Setup keeps transmitters and receivers linked even during interference, while ShowLink Ease technology enables remote adjustment of transmitter frequency, RF power, lock settings, and firmware updates directly from the receiver.
Each SLX-D+ system includes AES-256 encryption for secure transmission and Shure's patented Digital Feedback Reducer to help minimize unwanted feedback. Engineers can monitor and manage system performance via Wireless Workbench desktop software or the WWB Mobile app over Wi-Fi or Bluetooth. With rugged metal construction and up to 8 hours of operation using AA batteries or optional SB903 rechargeable batteries, the SLXD24D+/B58 delivers dependable, professional wireless performance.
