LARK1.0 Pro Wireless Microphone is a professional 2.4G wireless microphone system primarily designed for the education industry, ideal for sound reinforcement, recording, and broadcasting scenarios during teaching. Based on 2.4G wireless transmission technology, it creates an interference-free lecture environment with high performance and stability. The built-in intelligent algorithms—including Acoustic Feedback Cancellation, Automatic Gain Control, Adaptive Noise Suppression, and Room Acoustic Calibration—ensure every word is delivered clearly to students. The ultra-lightweight and compact transmitter frees the teacher’s hands, while the 86-box receiver supports both UAC digital output and analog outputs for flexible integration.
