Mic Preamps

If you are talking about microphone preamps, they take very small signals (on the order of millivolts) and apply gain to bring them to line level (on the order of a volt or so).

The input impedance is optimzed for microphones (low impedance) but some have instrument inputs that are optimized for guitars and basses (high impedance).

There are a lot more esoteric details that could be covered, but are probably only of interest if you are looking for a certain 'sound'.
