Many Op-Amped Active Crossover Network

Matttcattt · 21st June 2004, 07:57 PM

I dont know where to put this, but as it is active, I thought it would fit best here.

I saw a while ago a site containing verious crossover designs, the most recent being an active network containing at least 16 Op-Amps. It had bandpass and notch filters for four channels, one each for bass, mid-bass, midrange and high frequencies. I cannot remember the web address. Does anyone know what im talking about?

Perhaps you were thinking of Jens Rasmussen's DELTA ACTIVE FILTER ONE at:

http://www.delta-audio.com/Active%20filter%20one.htm

Great manual explaining the filter types, schematics etc.

His DIYaudio ID is "JensRasmussen"

Yes! Thank you very much.

Ive been searching for ages, but "active crossover" is a bit vague a search term.

[edit]: Thank you again.
