The project for the IFEC 2024 competition was the development and design of a stereo audio amplifier in class D with two stereo channels and one subwoofer channel. The nominal power of the device is 420 W, and the efficiency is 96.2%. Compared to conventional amplifiers, the advantages of this device include improved energy efficiency, better sound quality and frequency response, as well as reduced weight.
We won the 4th place and The Best Sound Quality Award. In a subjective test, the judges rated the sound quality of our device as the best compared to all other teams in the competition.
