Based on Quattuor, Unus is a stereo multimedia speaker system capable of delivering up to 4.7W per channel. Unlike Quattuor that has four controls, this circuit has one control for volume. Shown here is the prototype PCB (printed circuit board). The difference between this and the final circuit (that will never be materialized), is that the final circuit uses two additional bypass capacitors in order to improve supply filtering. The circuit uses two TDA2003 power amplifiers. Both components side and copper side are shown.
