4 Way Crossover for the MonsterSpeakers
Today marked another milestone; the cross-over for my 4 way active speaker is done. The input is a XLR followed by a very common instrumentation amplifier before entering the real crossover it is buffered and split to the signal detection circuitry. This last bit of circuitry is not mine; I originally designed one with a 2.5v voltage reference and another one with a comparator with build-in reference like a LT6703HV however, Rod Elliott’s idea on Project 38 was very nice; a simple dual op-amp and voltage divider.
