I use a deqx; about 3k$, however, I have tried with good success the Behringer dcx 24/96. However, I have heard great things about marchand xovers if you like analog. I really need the steep (up to 300db octave) slopes a digital gives me, as the 20s suffer from standing waves/cancelation. I am sitting at 96db now for low to mid/high, 24db to sub.
Tell me though: I have read the manual on recombine, It seems that if I set the CC2 freq to 200 (2x 100) then what is below 200 does go to the mains, and currently I have the mains set to bypass, so output is full range. (actually in my situation, it is only 40hz to 325hz as xover by the DEQX, and the below 40 of the mains goes to the sub.) What I want is the 40hz cutoff be handled by the ICBM, but the manual makes it sound like if recombine is on, and mains set to 40, then the sub output will be 40 and below, but the mains will still be full range (at least as much of the range as I feed it) Is this true? Or does it apply the 40hz high pass to the mains output too?
