The traditional wireless microphone has finally met its match. Introducing the S-Track Lark 100, powered by cutting-edge Nearlink technology. It delivers an “invisible amplification” experience, ensuring every word is heard clearly in every corner of the room, without any of the traditional hassles.

Designed for Educators, Engineered for Excellence

We’ve solved the core challenges of classroom audio to create a seamless teaching partner.

Feather-Light Freedom: At just 10g, the compact transmitter is lighter than a coin. Clip it to your collar or wear it around your neck for complete freedom of movement during lessons, board work, or demonstrations.

Intelligent Sound Field Calibration: Four advanced audio algorithms (feedback suppression, automatic gain control, noise suppression, and equalization) work together to isolate your voice from background noise. With a signal-to-noise ratio >=80dB, every student, even in the back row, will hear you perfectly.

All-Day Power: Enjoy up to 6 hours of use on a single charge. The portable charging case provides additional charges, extending total battery life to 18 hours for uninterrupted, all-day teaching.

The Nearlink Advantage: Smarter, Clearer, Simpler

Next-generation Nearlink technology is at the heart of the Lark 100, delivering three key benefits that set a new standard for wireless audio in education.

Unshakably Stable Connection: Using the robust Nearlink SLE protocol, the Lark 100 maintains a rock-solid connection up to 20 meters, even through walls. Its automatic pairing allows transmitters and receivers to connect instantly, enabling simultaneous use in multiple classrooms without interference and boosting deployment efficiency by 90%.

Studio-Quality Audio: Experience CD-quality, 16bit/48kHz lossless audio transmission with a sampling rate twice that of conventional Bluetooth. This captures the subtle nuances of your voice and teaching aids. Smart voice enhancement also optimizes recordings, reducing post-production noise reduction costs by 70%.

Truly Effortless Operation: With NFC one-touch connection, pairing is instant—just power on and tap. An intuitive single button handles power and mute, making it accessible for every educator, regardless of tech skill.

Adaptable to Every Learning Environment

The Lark 100 seamlessly integrates into your existing educational spaces.

Standard Classrooms: The receiver fits discreetly into a standard wall (86-type) box, with the charging case stored neatly at the lectern. Dual analog outputs support both room amplification and recording simultaneously.

Lecture Halls & Auditoriums: Easily connect to a PA system to cover spaces of up to 300 people. Experience stable, delay-free audio transmission up to 60 meters, perfect for educators who move around while they teach.

Remote Collaboration: The UAC digital output ensures high-definition audio for live streaming, online classes, and cross-campus collaboration, making resource sharing smoother than ever.

A Global Vision, Powered by Domestic Innovation

The Lark 100 is equipped with a 100% domestic RISC-V chip and features deep integration with HarmonyOS for seamless “one-touch” connectivity. Future updates will enable smart campus ecosystem management. As a member of the Nearlink Alliance, our technology is gaining international recognition, with multi-language noise reduction solutions in development to serve global education markets.
