Scheme Description:

In the multimedia audio-visual classroom, the teacher can operate the computer and physical display devices such as painting, follow one's inclinationsly text, projection, audio, video and other modern teaching media, as an education wisdom, intelligent multimedia audio-visual teaching room, a complete set of audio and video management system is very necessary, source device is mainly composed of multimedia audio-visual classroom blackboard in the classroom, copy and play equipment, computers, audio, etc. Through the matrix system to make a variety of signal sources more convenient and rapid interconnection with a number of display devices.

Case application:

1. Releasing the shackles of the traditional program on the speaker, the speaker can walk freely in the classroom without wearing any audio picking equipment.

2. Adopts AI artificial intelligence speech separation and feedback elimination algorithm, which can achieve good sound amplification effect no matter the speaker is far or near to the microphone.

3. The two microphones do DSP distributed processing, and the two microphones work together to pick up sound evenly in the podium area. When the speaker speaks in the podium area, the sound amplification effect has no obvious difference, which avoids the result that the single microphone has obviously different sound amplification effect due to the difference of the distance between the speaker and the microphone.

4. It has a unique fade-in and fade-out switching mode function. When two capacitors are connected at the same time, the signal received by MIC of one capacitor is higher than that of the other one, the fade-in and fade-out switching is carried out, and the switching process is smooth without eating words or dropping words.
