[QUOTE="Rockman, post: 153136, member: 545869"] The 12V input voltage is rapidly turned on and off by a set of transistors. That allows transformer action to take place. The switched voltage is then stepped up by the power supply transformer to a higher voltage. That voltage is the rectified by diodes and smoothed out by capacitors. Then the voltage is applied to output transistors. A small input voltage( your rca input) is applied to the transistor as well. This small voltage can control the much larger output voltage on the transistor coming from the power supply. Basically the small voltage makes the transistor, or whatever kind of output device the amp uses to either conduct more or less. The output voltage swing will (should) follow the input signal. Very basic explanation but there is alot more to it especially transistor theory and such... [/QUOTE]
