I thought active filters were ones that required a power supply ?
Its all semantics again. If they are in their own own box with some buffers, or make them part of a feedback loop then its easy to call them an active filter. But put them in front of a power amp and claim they are not part of the power amp (which has a power supply and gain stages) then they magically are passive filters. In reality they are both the same. Just depends where you draw the lines. But strangely one is a good thing and the other evil.
I get ya. Thanks. :grin:
