Shure BLX288E/B58-K3E — Dual Wireless Vocal System for Stage and Events

The Shure BLX288E/B58-K3E is a complete dual-channel wireless microphone package pairing two BLX2/B58 handheld transmitters with the BLX88 dual receiver, all tuned to the K3E frequency band (606–630 MHz). Built for live vocals, conferences, weddings, and mobile DJ setups, this system delivers proven sound without the cable clutter. It is the right choice for performers and presenters who want professional-grade wireless reliability straight out of the box.

What Sets This Wireless System Apart

At the heart of each transmitter sits the Beta 58A, a supercardioid dynamic capsule known for its warm vocal character and tight feedback rejection in loud stage environments. The BLX88 receiver adds one-touch Quick Scan that automatically locates the clearest open frequency, eliminating manual tuning guesswork during setup. Together, the system supports up to 12 simultaneous compatible channels per frequency band, making it well suited to multi-mic productions.

Who Should Choose the BLX288E/B58-K3E

This model is the right choice for vocal duos, worship teams, conference hosts, and mobile DJs who need two dependable wireless channels without complicated setup. The supercardioid Beta 58A capsules handle lead and harmony vocals equally well, while the dual receiver keeps the rig tidy in a single unit. Bands upgrading from entry-level wireless systems will appreciate the 14-hour battery life and the freedom to roam up to 100 m from the stage. Event professionals running weddings or panel discussions benefit from Quick Scan, which finds clean frequencies in congested RF environments.
