Active - Description :
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 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 after amplifiers where power levels are much larger . |
