Shure BLX4 Wireless Receiver — H11 Band (572-596 MHz)
BLX4 Overview
The Shure BLX4 is a single-channel analog wireless receiver built for the BLX Wireless System, operating in the H11 frequency band (572-596 MHz). It features microprocessor-controlled internal antenna diversity for consistent signal integrity, along with frequency QuickScan to identify and lock onto clean frequencies quickly. Designed for houses of worship, corporate AV, live performance, and rental applications, the BLX4 delivers a straightforward deployment path without sacrificing RF reliability. A two-color audio status indicator LED provides at-a-glance monitoring of signal and audio levels during operation.
Group and channel scan simplifies coordination across multiple units, making the BLX4 a practical choice for integrators and engineers managing multi-channel wireless setups.
