This is my stumbling block. I have a kit preamp (lite audio a-15) which I dont know the impedance to. I have attached the schematic. Its supposedly a clone of a ML 20.5...I doubt it shares much with the actual ML product, however ive been unable to find anything better than it so far. Anyway I do not know its input impedance.

TO further complicate things, I do not have access to the schematics for the MD10 so I have no way to figure out where the gain is set.

My reason for wanting to attenuate is that my preamp has very little volume control.
