What is the theory behind what's going on here? Would anyone mind explaining to me how this add-on works?
The differential op-amps use the varying currents to undulate the filter frequencies, right? Voltages coming into the op-amp inputs are changing, and their difference is output by these LM's as a current proportional to the difference in voltages are the inputs.. so as the input voltages change, the output currents change along with them and feed a bunch of resistor+capacitor LP/HP filters?
Thanks again Alex Your on fire pumping them out like crazy. I have a couple more weeks on the lm13600 chips. I sawthe one guy said it was better without But ill have to try for myself. I didnt really car for the mxr phase 100 6 stages might be too many i guess this has 8
