BLX24R/SM58 Overview
The Shure BLX24R/SM58 delivers professional wireless vocal performance in a rack-mountable configuration designed for fast deployment and reliable operation. The system centers on the legendary SM58 handheld transmitter microphone, paired with the BLX4R half-rack single-channel receiver, operating in the J11 frequency band (596–616 MHz). With up to 14 hours of battery life from two AA batteries, this system is built for extended live performance, houses of worship, and installed sound applications. Audio engineers and system integrators will find the BLX24R/SM58 ready to perform straight out of the box with minimal configuration required.
