Shure SM39 Microphone: The Acoustic Revolution for Stage Performances

In modern stage performances, the microphone is not only a tool for capturing sound, but also a bridge between the artist and the audience. Shure launchedSM39 head-mounted microphone, redefining the audio standard for stage performances with superior acoustic performance, ergonomic design and cutting-edge wireless technology.

1. Design philosophy: the balance between comfort and performance

The SM39 is designed for high-intensity stage performances, with design details that reflect ingenuity:

• Lightweight and unburdened: The weight of the bare metal is only 54-55 grams, with a streamlined head beam structure, and there is no sense of pressure when worn for a long time;

• Dynamically stable: Adjustable cantilever and shockproof bracket with hydrophobic coating shell to calmly cope with intense limb movements;

• Hidden aesthetics: The low-key metallic shell blends perfectly with a variety of costumes, ensuring professionalism and trendiness.

Sweat-resistant plating and sealed microphone protection ensure reliability in extreme environments – whether it's sweat-soaked or bumped, the sound quality is always the same.

2. Acoustic performance: Accurately capture every note

Quick overview of core parameters

Dynamic range up to 112dBEffortlessly covering the detonating highs from whisper-like softness to rock scenes, the SM39 accurately restores every detail of the sound, whether it's pop, K-Pop or hip-hop.

3. Cutting-edge technology: unleash wireless freedom

1. Axient Digital Wireless System Compatibility

The SM39 is deeply integrated with the Shure wireless ecosystem, supporting full-band scanning and 20-bit high-resolution transmission for Axient Digital systems. With the help of adaptive frequency selection technology, the interference frequency band is automatically avoided, and the frequency interruption and zero noise are maintained in complex electromagnetic environments such as concerts and music festivals.

2. Dynamic range extension

With a multi-stage compressor (adjustable from 10:1 to 40:1) and an instantaneous peak suppressor, the SM39 is able to handle extreme dynamics from faint airs to roaring singing, avoiding distortion while preserving impact.

3. Real-time feedback suppression

The built-in Anti-Feedback Canceller accurately identifies and eliminates resonance frequencies, and with the supercardioid polar pattern, it achieves clear vocal transmission with zero feedback in large stadiums.

4. Scene adaptation: one microphone with multiple stages

1. Large-scale concerts

Equipped with the SM Series' exclusive windscreen, it ensures clean and transparent sound even on windy outdoor stages, such as rock festivals. The TA4F connector is designed for quick disassembly and assembly, which is convenient for emergency adjustment at the sideline.

2. Stage interactive plays

The compact size and flexible pointing adjustment allow the actor to move without having to worry about the microphone position during the movement, dance or martial arts performance, and the director can remotely control the gain and mute to ensure the flow of the narrative.

3. Virtual idol live streaming

The low-latency digital audio output supports real-time streaming, and the AI noise reduction algorithm eliminates room reverberation, making the virtual anchor's voice as vivid as a live stream.

5. User experience: details define professionalism

• Rapid deployment: Integrated windproof net design, eliminating cumbersome installation steps; The intelligent battery level display (red/green/blue LED) provides intuitive feedback on the remaining battery life.

• Cross-device compatible: Support USB-C direct connection and wireless synchronization, laptops and mobile devices can be plug-and-play.

• Long-lasting and durable: Passed MIL-STD-810G military standard test, can withstand extreme temperature difference from -20°C to 60°C, and supports more than 500 times of severe bending without performance degradation.

VI. Conclusion

The Shure SM39 is more than just a tool, it's an extension of artistic expression. Its revolutionary dual-mode wireless architecture, precise sound field capture ability, and extreme environment resistance allow artists to completely free themselves from the shackles of technology and focus on the creation itself. Whether it is the shocking shouts of the stadium of 10,000 people or the delicate chanting of the small theater, SM39 always allows every emotion to penetrate time and space with stable and clear sound quality.
