Shure SLXD24D/SM58 Dual-Channel Digital Wireless Handheld Microphone System with SM58 Capsules (H55: 514 to 558 MHz)

The Shure SLXD24D/SM58-H55 is a microphone system that offers two independent channels and digital transmission for clear, reliable sound. It pairs a rackmount SLXD4D receiver with two handheld SLXD2 transmitters that carry SM58 capsules, a dynamic design with a cardioid pickup pattern trusted on stages around the world.

Because the audio stays in a 24-bit digital format, the system maintains a 120 dB dynamic range and only 3.2 ms of latency, so performers hear what they expect without noticeable delay. The UHF link works in the H55 band from 514 to 558 MHz, giving you 44 MHz of tuning range and 1,760 selectable frequencies that help you find a clean channel even in busy RF environments.

The SLXD4D receiver uses true diversity circuitry to reduce dropouts. Quick IR sync locks each transmitter to the receiver, while an Ethernet port enables coordinated scans and control across as many as 32 compatible systems on the same network—ideal for multi-mic conference rooms, mid-sized music venues, and rental inventories that need fast setups.

Each handheld runs up to eight hours on two AA batteries, and you can swap to the optional SB903 rechargeable pack when you prefer a sustainable power solution. With an operating range that reaches up to 328 feet line of sight, presenters and vocalists can move freely across large stages, lecture halls, and houses of worship without worrying about signal loss.

Whether you manage corporate events, install sound systems in performance spaces, or tour with a small band, the SLXD24D/SM58-H55 delivers the sound quality, battery life, and network-ready control features that keep shows running smoothly.
