- A active circuit works with an external power supply and usually at low power. A passive circuit operates directly on a signal using the power coming from the surrounding circuitry.
This is the . Used . reason why an active crossover is, for the most part, placed before amps, containing integrated circuits (and line level signal processing). On the other hand a passive crossover is placed . Used . after amplifiers where power levels are much larger . ...Crossfade
