[sdiy] isolator vs low/band/high pass filter

[Jean Bender]

Hi !
I need again your knowledge and explanations.. I'm wondering how works
an isolator, and if it can be made using several filters in parralel..
If i get it, it's just a sound source splitted into three different
frequencies, and for each one a volume control ?
SO, is it a bad idea to use three filters without resonance control to
do that ? I"ve got some lm13600 spare, and was thinking about it.

If somebody here has already built an isolator.. i would be interested
in talking about that !

cordially !
Jean
