Description：
The digital audio processor uses environmental noise suppression technology, automatic equalization technology, intelligent mixing technology and echo cancellation technology, etc., to solve the echo and noise problems of interactive recording and broadcasting classrooms.
Features：
1. It adopts industrial embedded architecture, adopts dedicated chip and embedded operating system, which is stable and reliable.
2. Integrated automatic noise suppression technology (removal of noise interference including air conditioners, exhaust fans, etc.) to ensure sound quality.
3. With echo cancellation function, the mix of wireless microphone and hanging microphone needs to be processed by AEC, and the reference signal is remote audio signal.
