Passive line filter (Oris Horns)

Hi Martin,

Nice setup!

Why do you use the filter between your pre-amp and the bass amp? It was not designed for that use....that filter should be connected between the output of your main amplifier and the bass amplifier....

If you have enough gain(!!) then you can use such a filter between the pre-amp and bass amp but in that case I would increase the value of the resistors and at the same time reduce the value of the capacitors.

10x resistor value means ten times less value for the capacitors for the same filter character.

If you are using a buffer for the bass amp then connect the filter after that, this will then influence the output of your pre-amplifier the least..
