The simple solution is calibrate at full gain, even if that is
too sensitive for practical use. Then depending on the circuit,
you could just remove the pot (if it is used as a divider), or
replace it by a fixed resistor of the same value.

A multiface is an excellent card for measurements (no pots at
all). Another good one is the RME RPM. It's easy to bypass the
RIAA preamps (just a few alsamixer commands), and the outputs
are *real* balanced (i.e. two signals with opposite polarity).
