Shure BLX288E/SM58 Wireless set H8E: 518-542 MHz

Dual Wireless Vocal System with Legendary SM58 Clarity

The Shure BLX288E/SM58-H8E brings dual-channel wireless freedom to vocalists, presenters, and worship teams in the 518–542 MHz UHF band. Two BLX2 handheld transmitters with SM58 capsules work alongside the compact BLX88 tabletop dual receiver, delivering warm, clear vocal sound immediately. Setting up is fast with one-touch QuickScan technology, which finds the cleanest frequency from 123 available. Each channel features a two-color audio status LED: green for normal, red for overload or clipping, offering instant visual feedback.

What Stands Out About This Dual System

Two SM58 capsules are included — eliminating the need to buy microphones separately, a detail that sets this model apart for busy venues. Microprocessor-controlled antenna diversity in the BLX88 receiver helps maintain a stable signal, even in crowded RF environments. Unexpected volume spikes are controlled by a -10 dB gain attenuation switch.

Wireless Performance and Connectivity Specs

Technical details assist users in setting up for stable, interference-free performance in any room size.

• System Type: UHF wireless — reliable analog transmission compatible with many venues and regions
• Frequency Band: 518–542 MHz (H8E) — a band dedicated to European operation supporting up to 12 simultaneous systems
• Frequency Response: 35 Hz – 20 kHz — captures full-range vocal warmth and clarity
• Moving freely up to 100 m line of sight is possible on stage, in halls, or places of worship.
• Battery Life: 14 hours on 2× AA — enough for all-day events without swapping batteries

Optimized for Dual-Microphone Setups

This system is ideal for teams, DJs, conference organizers, and small-venue performers who require two handheld microphones to work at once, without frequency clashes. Rugged construction and simple setup serve both traveling and fixed-location users well. Educators and presenters benefit from the SM58's cardioid pattern, minimizing feedback from monitors or room echoes. Space-saving tabletop receiver design suits portable PA systems and temporary installations.

The SM58 Capsule: Industry Standard in a Wireless System

SM58 capsules have long been chosen by professionals for their durability and predictable sound. Incorporating this trusted element into the BLX wireless system allows the same vocal quality that made SM58 famous to be accessed in wireless form.
