Shure SLXD24D/SM58 Dual-Channel Digital Wireless Handheld Microphone System with SM58 Capsules (G58: 470 to 514 MHz)

The Shure SLXD24D/SM58-G58 is a wireless microphone package that gives you two independent channels of crystal clear, 24-bit digital audio for spoken word or vocal performances. Each channel relies on an SLXD2 handheld transmitter paired with the industry standard SM58 capsule, so voices cut through the mix while background noise stays under control. Operating in the G58 UHF band from 470 to 514 MHz, the system delivers a wide 120 dB dynamic range and keeps latency at a swift 3.2 ms, making it a strong fit for live sound where timing and clarity matter.

At the heart of the setup is the SLXD4D rackmount receiver. Its dual front-panel antennas use predictive switching diversity to keep the RF link stable, even when performers move across a stage up to 330 feet from the rack. An automatic scan routine finds clean frequencies in seconds, and IR sync locks each transmitter to the receiver with one button press. Separate XLR and quarter-inch outputs on the rear panel simplify routing to mixers, recorders, or powered speakers, while an Ethernet port allows network control or integration with Shure Wireless Workbench software when you manage multiple systems.

Each SLXD2 handheld runs for as long as eight hours on two AA batteries, or on the optional Shure SB903 rechargeable pack for venues that prefer a more sustainable power solution. The capsule mount follows Shure’s interchangeable design, so you can swap the SM58 heads for other Shure options if a different pickup pattern or tonal character is required.

This system feels right at home in mid-sized houses of worship, corporate presentation rooms, school auditoriums, or music clubs that need two reliable wireless microphones without the complexity of larger touring rigs. Engineers can deploy up to thirty-two SLX-D systems in one frequency band, giving you room to scale as events grow.
