Shure BLX24R/B58 Rackmount Wireless Handheld Microphone System with Beta 58A Capsule

The Shure BLX24R/B58-H9 is a wireless handheld microphone system that pairs the renowned Beta 58A capsule with a rack-mountable BLX4R receiver. It is built for singers, speakers, and hosts who need dependable sound without a complicated setup.

The Beta 58A capsule inside the transmitter has a dynamic design and a supercardioid pickup pattern, so it focuses on the voice and minimizes bleed from instruments or stage noise. Performers in small clubs, wedding venues, houses of worship, and corporate rooms rely on this capsule for its consistent clarity and resistance to feedback.

Setting up is straightforward. Mount the BLX4R receiver in a standard rack, power it on, and press QuickScan. The receiver automatically finds the cleanest channel from 123 available frequencies, limiting the chance of interference even when multiple wireless systems are active. An easy-to-read LCD shows signal strength, audio levels, and the selected group and channel.

The handheld transmitter runs up to 14 hours on two AA batteries, giving you an entire day of rehearsals, services, or back-to-back events without a battery swap. A reliable 300-foot line-of-sight range lets you move freely across stages, aisles, or conference floors while keeping audio stable. When you need to adjust input sensitivity, the built-in gain control on the transmitter makes quick level matching simple.

On the receiver, balanced XLR and unbalanced 1/4-inch outputs connect easily to mixers, powered speakers, or recording interfaces, so the system integrates smoothly into existing rigs. Rugged construction on both the microphone and receiver ensures they can handle frequent transport and daily use.
