The input voltage (from your battery or PSU) is dropped by a 7812 voltage regulator (or a simple zener+transistor circuit) to provide a stable 12V (or 5V) for the LM324 op-amp. Note: This is a critical flaw—if the battery voltage drops below 7V, the op-amp loses control. The XH-M203 is a compact audio amplifier module
