Shure BLX24R/B58 – Rack-Mount Wireless Vocal System

Product Overview

The Shure BLX24R/B58 is a rack-mount analog UHF wireless vocal system built for permanent commercial AV installations, houses of worship, and equipment racks. It pairs the rack-mountable BLX4R receiver with a BLX2 handheld transmitter and the Beta 58A supercardioid capsule for clear, feedback-resistant vocal capture. The rack-mount form factor makes it a clean fit for integrators standardizing wireless microphone systems in AV racks.

Product Description

This rack-mount wireless vocal system combines dependable wireless operation with the Beta 58A capsule for conference rooms, auditoriums, training rooms, and worship spaces. The BLX4R receiver is designed to mount in a standard equipment rack, keeping wireless gear organized and secured in fixed installs, while its audio output integrates with house mixers and DSP. The Beta 58A handheld transmitter delivers a tailored supercardioid pattern that rejects off-axis sound for strong feedback control. Each BLX transmitter runs up to 14 hours on two AA batteries with an operating range of up to 300 ft (100 m) line of sight. The system is available across multiple frequency bands (H9, H10, H11, J11) for clean RF coordination. For a tabletop receiver version, see the Shure BLX24/B58, or the Shure BLX24/SM58 for SM58 capture.
