Good morning, good evening all !
I'm asking for your help.
I would like to add/create a summing and a gain stages to an existing crossover design (from the 3-Way Linkwitz Riley Crossover circuitry by Rod Elliott) but my skills are not sufficient.
How could I correctly set the gain stage as follow ?
Potentiometer fully counter-clockwise = full kill
Potentiometer at 0 = unity gain
Potentiometer fully clockwise = +18db
How could I summ the Hi/Med/Low channels ?
My idea :

Would you mind helping me out with the design and components value?
Thanks !

A pretty standard volume circuit would be a Baxandall active volume circuit, which is mentioned (section 2) in Rod Elliot's site: ESP - A Better Volume Control
Summing from low-impedance sources can simply a question of combining with resistors and buffering with non-inverting opamp.
