The D100W D100R NearLink Wireless Microphone System is designed for educational applications, providing clear and stable sound reinforcement and recording for classroom teaching and lecture capture. With advanced NearLink wireless transmission technology, it creates an interference-free teaching environment. Powered by a domestically developed RISC-V processor, the system ensures high performance, low latency, and exceptional stability. Integrated with intelligent algorithms such as feedback suppression, automatic gain control, smart noise reduction, and intelligent sound field calibration, the microphone delivers clear, consistent audio across the entire classroom without volume fluctuations. Its compact, lightweight design ensures a comfortable fit throughout the class. Compared with traditional handheld microphones, it frees the user’s hands for natural gestures and movement. Compared with far-field microphones, it provides superior sound quality and a wider pickup range, allowing free movement without loss of clarity.
A complete microphone set includes a charging case, a transmitter, and a receiver. The charging case enables quick recharging of the transmitter, while the receiver supports both UAC digital output and dual analog outputs for flexible integration into various classroom systems.
