Advantages of the plan
Ultra-long and ultra-wide range sound collection - One array microphone for the entire classroom area can achieve sound pickup in all directions and throughout the entire classroom. Collect the sound information of the courseware completely.
Speak freely and easily - Omnidirectional array microphones replace traditional directional microphones, achieving sound collection without blind spots throughout the classroom. This not only frees up teachers‘ hands but also minimizes the difficulty of use to the greatest extent.
Super strong noise reduction capability - Intelligent adaptive noise reduction algorithm, capable of handling steady-state noises such as air conditioners and fans, as well as transient noises like knocking, flipping books, dragging stools, ringing bells, and cicada chirping. And it does not damage the human voice quality, and the recorded sound is clear and natural.
Adaptive multi-party echo cancellation - In remote two-party or multi-party interactive teaching, the AEC adaptive echo cancellation capability is utilized to completely eliminate echo phenomena, enabling simultaneous interaction among multiple classrooms.
Perfectly realizing classroom interaction, sound amplification and recording - with completely independent intellectual property rights core algorithms, the three major parts of interaction, sound amplification and recording are processed by different units respectively, ensuring that the quality of interaction, sound amplification and recording is perfectly compatible with each other.
The system has excellent stability and saves maintenance costs - 1-2 array microphones are easy to install without affecting the classroom‘s simplicity and beauty, and no decoration is required. The entire system requires no debugging at all and can be used immediately after installation.
AI2000 sound reinforcement interactive audio processor, adopting professional audio processor chips, 4 cores, 1.5G main frequency It is also equipped with industry-leading audio preprocessing algorithms such as Automatic Feedback Suppression (AFC), Automatic Noise Suppression (ANS), Automatic Echo Cancellation (AEC), automatic Gain Control (AGC), reverberation suppression (ARR), stationary noise, transient noise, and beamforming, which can effectively improve the quality of voice amplification interaction. It is equipped with a 2*150W power amplifier module, which can provide outstanding audio quality performance, featuring clear, delicate and layered sound effects, making the sound amplification more realistic and dynamic.
LM600 bar array microphone
The LM600 array directional microphone is equipped with 6 high-quality professional condenser sound heads and a deep suppression circuit, which has strong anti-interference ability and endows the microphone with excellent performance. 180° directional sound pickup, high sensitivity, and clear sound pickup within an 8-meter range. The pre-circuit ensures the microphone‘s excellent frequency response characteristics, with full sound quality, high fidelity, compact and beautiful appearance, and flexible and convenient installation. Designed specifically for high-frequency response, high sound pressure and low latency transient response processing applications in teaching interactive environments, it is mainly used for teaching sound reinforcement, interaction and long-distance sound pickup. Recording, meeting, broadcasting, speech and other scenarios.
