Shure BLX24E/B58-M17

Shure BLX24E/B58-M17 Wireless Vocal System — Beta 58A Capsule

The Shure BLX24E/B58-M17 wireless handheld microphone system is built for singers, presenters, and event hosts who need dependable, cable-free vocal performance in a ready-to-go package. The system pairs the BLX4 single-channel receiver with the BLX2/B58 handheld transmitter, which carries an integrated Beta 58A supercardioid dynamic capsule. The M17 frequency band designation identifies the regional variant tuned for compliant operation in the markets Muziker serves.

Setting up the system takes moments rather than minutes. One-touch QuickScan on the receiver sweeps the available spectrum and locks onto the cleanest open channel, while Group and Channel buttons on the transmitter mirror that selection with a single press. Microprocessor-controlled internal antenna diversity on the BLX4 keeps the RF link stable as the performer moves across the stage.

What Sets the BLX24E/B58 Apart in Its Category

Two design choices give this wireless set a real edge at its price point. The Beta 58A capsule is a true supercardioid dynamic — its tight polar pattern rejects off-axis stage noise and monitor bleed far better than the entry-level PG58 found in cheaper BLX bundles, making it a smart upgrade for vocalists who fight feedback in loud rooms. The BLX4 receiver's QuickScan logic is paired with a two-color audio status LED, so the operator sees at a glance whether the channel is clean, clipping, or muted.

Wireless Performance and Range — Vocal Freedom on Stage

Range and reliability matter most when a vocalist leaves the mic stand. The BLX platform is engineered to keep the signal solid across typical stage and venue distances, with up to 12 compatible systems able to coexist per frequency band for multi-mic productions.

• Operating Range: 100 m line-of-sight — enough to walk the room, work the crowd, or roam a small-to-mid venue without dropouts
• Up to 12 simultaneous systems per band allow for scaling from solo gigs to full band or panel setups.
• Frequency Response: 50 Hz–15 kHz — captures the full body of a vocal performance from low chest tones to airy highs

Power and Battery Life — Show-Length Endurance

Wireless transmitters live or die by their battery story. The BLX2/B58 runs on a pair of standard AA cells, so spares are easy to source anywhere in the world — no proprietary packs, no charging dock required mid-tour.

• Battery Powered: Yes — runs on two AA batteries included in the box
• Battery Life: up to 14 hours of continuous use — covers long sets, conferences, and multi-act evenings on a single pair
• Power and Battery Status LED: on transmitter — visible warning before the cells run flat

Receiver and Capsule Specs — Built for the Working Performer

The receiver and capsule combination is what defines the daily experience of using this system. The BLX4 sits on a table or rack shelf, the BLX2/B58 sits comfortably in the hand, and the Beta 58A capsule does the heavy lifting on tone.

• Microphone Capsule: Beta 58A dynamic, supercardioid — focused vocal capture with strong feedback rejection
• Receiver Outputs: 1 x XLR, 1 x 1/4" — feeds any mixer, PA, or audio interface without adapters
• Antenna Diversity: internal, microprocessor-controlled — maintains a stable link as the performer moves

Who the System Is For

This wireless bundle is the right choice for working vocalists, worship leaders, MCs, and event hosts who want a proven wireless setup without stepping into the price bracket of Shure's SLX-D or QLX-D lines. Solo singers performing in clubs, churches, and small theaters will appreciate the Beta 58A's feedback resistance and the system's quick setup between acts. DJs adding a wireless mic to their rig, schools running theatre productions, and conference presenters who need a reliable handheld will find the 14-hour battery life and 100 m range more than adequate. Anyone moving up from a budget wireless bundle benefits most from the supercardioid capsule and the QuickScan workflow.

Shure and the BLX Wireless Line — Built on Decades of RF Engineering

Shure has been designing professional wireless microphone systems since the 1950s, and the BLX series reflects that accumulated experience in an affordable, easy-to-operate package. The Beta 58A capsule at the heart of this set shares its lineage with legendary dynamic microphones — a family trusted on stages worldwide for decades. BLX systems are available in vocal, guitar, headset, and lavalier configurations, letting performers start with a single handheld and expand into bodypack setups as their needs grow.
