OK, they don't really spec an output impedance,

and, I imagine that might depend on whether or not on engages the "gain" portion of the circuitry.

But, assuming the input impedance of your FP 2 is, in fact, 100k or better, and, presuming that the maximum output impedance of the passive is approximately 10kOhms or less, then it may just be that it will all work out.

That, of course, is a lot of assumptions, but I really can't see that you could hurt anything by trying. Chances are, though, that you won't have a lot of control range, 'cause unless the FP 2 has been modified, it will have a lot more gain than you need. You may want to try BOTH sets of attenuators at their minimum settings at first, then experiment with what you consider to be the optimum setting on the FP 2, given good sound and a good control range from the passive.

Once you have established this, you may wish to go no further. Or, if you want to bypass the selector and attenuators on the FP 2, you will have a bit more info.
