Overview

The Shure BLX24R/B58 Rack‑Mount Wireless System is designed for professional performers, presenters, and installed sound environments where dependable wireless audio matters. It combines the BLX4R rack‑mount receiver with the BLX2 handheld transmitter housing the Beta 58A microphone capsule. This package ships with essential accessories for quick, tidy integration into existing rigs, including rackmount hardware, antennas, a power supply, a microphone clip, two AA batteries, and documentation. The system emphasizes practical reliability, clean signal handling, and straightforward setup that fits venues ranging from small clubs to larger halls.

Frequency and Range

Operates in the H10 (542–572 MHz) UHF band, a spectrum that supports stable wireless transmissions in regions where it is authorized. Always verify local compliance before ordering to ensure a smooth, compliant deployment. The design supports up to roughly 300 ft (100 m) of line‑of‑sight coverage, enabling performers to move freely while maintaining a solid connection.

Power, Performance, and Capacity

The handheld BLX2 transmitter delivers long‑lasting performance, with typical operation up to 14 hours on two AA batteries. This extended endurance minimizes mid‑set interruptions and makes it suitable for longer performances or multi‑set events. On the receiver side, the BLX4R provides a reliable, rack‑mountable home for the system with straightforward control and monitoring, while remaining compatible with multiple channels per band for future expansion.

Real‑World Use and Setup

Designed with professional environments in mind, this system works effectively for concert stages, houses of worship, conference venues, and touring installations. A key value is QuickScan—Shure’s frequency selection tool that helps identify clean channels quickly, reducing setup time and lowering the risk of interference in busy RF environments. When you’re preparing for a show or a speech, the BLX24R/B58 setup offers flexibility without compromising on reliability.
