With the help of the book "Small Signal Audio Design" (Self Douglas), I'm trying to design a simple and cheap line mixer, mainly for monitoring.
I've tried to drawn a simple stereo input channel and this is what I came up with so far.
Now I need to connect the three pre-fader AUX sends. I want the stereo signal to be mixed in mono before hitting each AUX send.
I've seen various schematics where the signal from L and R is passively summed with 3.3K resistors. But I don't understand if I should take the signal before or after C15.
What would it be the difference?
Should I put additional coupling capacitors too?
thank you and sorry for the noob question
