Overview

The Shure BLX288/SM58-H9 is a complete dual-channel wireless vocal system built around two of the most recognized microphone capsules in professional audio — the SM58. Each handheld transmitter integrates a genuine SM58 cartridge, delivering the same warm midrange presence and effective pop rejection that has made the SM58 an industry standard for decades. The included BLX88 dual-channel receiver manages both channels simultaneously, making the system ideal for duets, co-hosted events, worship services, or any application requiring two independent wireless vocal channels.

Setup is intentionally straightforward: power on the receiver, sync the transmitters, and you're performing within minutes. The system operates across a 300-foot range and each transmitter runs for up to 14 hours on a pair of AA batteries, so reliability during long events isn't a concern. With support for up to 12 channels per frequency band, the BLX platform also scales for larger productions that need additional wireless channels. The complete kit ships with the dual receiver, both transmitters, mic clips, batteries, and a power supply — everything needed to go wireless out of the box.
