I’m glad to hear you were able to get the new one working…although I still think you could have successfully repaired the first one. There is a table in the owner’s manual that shows the crossover frequencies based on the dip switch settings. When the phase switch is on the “in” setting, the crossover frequency doesn’t matter because both sides are going up and down the same…there are no frequencies crossed over. But you still can determine the amount of highs and lows you hear based on how the trim pots are set.
I hope that answers your question.
Enjoy your Quaverato!
