I need to sum the 4 discrete line outputs of my Bose 4401 preamp to feed the 2 sub inputs on the discrete line inputs on my Marantz receiver. How do I do this without losing separation between them? I get the low freq but also some mids which I don't want. The Marantz doesn't seem to be able to fix this for the discrete LF analog inputs
Is there a simple passive circuit that can do this and if so, how much gain would I lose?
Or is there some simple active box that can do this at low cost. I know I could use a 4ch mixer and mix down the 4ch to a L and R and then use an electronic crossover but that seems complicated and expensive. I'd like to feed everything below about 50 Hz to the sub inputs for my 18" Gauss 12 cu ft sub cabinets.
Also how important is it to sum all four outputs, or should I just be using the front two outputs?
