Lol...I thought of putting a "but Dave will disagree" in my post and now wish I had.

The tricks used by manufacturers to talk about things like amp power or frequency response are the bits that everyone NEEDS to know before making a purchase or integrating one bit of gear with another.
Beyond that, the OP says he only has a few weeks until the end of the course anyway, hence my suggestion to stick to the totally practical stuff rather than getting into underlying theory.
That's my story and I'm sticking to it!
That's what I do. I drink and I know things.
