Thank you very much for the response. It reminds me that I once talked to the late Bill Thalmann about this problem, and he suggested 20K resistors, too. But why a 20K pot vs a resistor on the positive leg?
In any case, the circuit if I tap off the linestage would be...
20K between the negative phase of the balanced output and ground.
20K potentiometer or resistor between the positive phase of the balanced output and positive of the SE output.
Is that correct? I guess the 20K pot on the positive leg would permit control of gain, but the subwoofers I plan on using have built in attenuators.
