This is a PCB for the Quattuor project. Basically it is a stereo amplifier with controls for volume, balance, bass and treble. This board in particular was defective by design and had to be rectified and repaired in order to work properly. The PCB is now connected to a pair of Visaton FR 10 speakers, as predicted in the final project. You can see it reproducing audio from the computer. In this video, all four sound control features of this project are displayed. The sound was recorded using the MP3 player attached to the camera, and the original soundtrack was replaced by the one recorded by the MP3 player.
