Digital power amplifier DN series

Digital amplifiers, also known as Class D amplifiers (also known as Class D amplifiers in China), have the basic circuit of existing Class D amplifiers. The main function of digital amplifiers is that music signals cannot be directly amplified and must be converted into switch signals first. The amplifier operates in a switching state, and the power transistor is a field-effect transistor. The output end of the power amplifier has a low-pass filter composed of a coil and a capacitor.

14. 4 * 4 analog channels, 4 * 4DANTE, 2 * 2 USB sound card, internal core algorithms APC, AEC, ANS, AGC, AM, POE: DC12V, replacing the original analog interface. The conference microphone is input through internal DSP processing, and DANTE digital transmission is transmitted to the system for seamless integration with the video conference host. By using two separate channels within the DSP, the AEC analog processing system can process four sounds, and by combining a USB sound card with a speech recognition system, the conference content can be recorded into files. Digital amplifiers have a stylish industrial appearance and are designed and manufactured specifically for commercial sound applications.
