Hi, I design all my schematics, layouts and final projects. A preamp raises the signal level from a source, like a CD player to a level sufficient for the power amps. It acts as a way to control the volume and selects the input source. Some include other features such as phonograph gain and equalization and headphone outputs. The one in the originally posted question has neither nor does the one I posted. There is a class of devices that incorporate the preamp and power amp functions in one unit. Usually called an integrated amplifier. It is convenient for the user, but not as flexible for enthusiasts.
Good Listening
Bruce
