SHURE BLX24RE/B58-K14 Wireless Microphone System

Shure BLX24RE/B58-K14 Rack-Mount Wireless Vocal System

The Shure BLX24RE/B58-K14 is a professional wireless system designed for permanent installations and touring applications where reliable 19-inch rack mounting is required. The core of this kit is the robust, metal BLX4R receiver, featuring advanced capabilities such as detachable antennas (allowing the use of antenna splitters), adjustable output level, and an informative LCD display with RF and audio level meters.

The system comes with a handheld transmitter equipped with a Beta 58A supercardioid dynamic capsule. The Beta 58A outperforms standard models due to its higher sensitivity and better isolation from off-axis noise, ensuring vocals remain clear even in noisy environments. The system operates in the K14 frequency band (614–638 MHz) and utilizes "QuickScan" technology, which finds the best available frequency at the touch of a button.
