SHURE BLX288E/B58-K3E Microphone

Shure BLX288E/B58-K3E Dual Wireless Vocal System with Beta 58A Microphones

The Shure BLX288E/B58-K3E is a professional two-channel wireless system that allows two microphones to be used simultaneously with a single compact receiver. This set is designed for vocal duos, event hosts, and bands looking for superior sound quality and easy operation. The system comes with two handheld transmitters featuring Beta 58A supercardioid dynamic capsules. Unlike standard microphones, the Beta 58A offers higher sensitivity and better isolation from ambient noise, ensuring clear and crisp vocals even on a noisy stage.

The system operates in the K3E frequency band (606–630 MHz) and uses "QuickScan" technology, which finds the best available frequency for both transmitters with a single button press. The BLX88 dual receiver features microprocessor-controlled internal antenna diversity, ensuring a stable connection and reducing the risk of signal dropouts. The transmitters operate for up to 14 hours on standard AA batteries, providing freedom of movement up to 100 meters.
