I know that a multimeter is incapable of reading the voltage the capsule actually receives due to loading induced thereof, but short of buying an expensive meter, is there a reliable method of ensuring the pattern in practice lines up with the settings on the knob?
This is necessary in general but more specifically I have a poctop/Dany D-12 and I notice that the resistors on the pattern switch are not changed from stock APEX 460 values and thus do not reflect the original AKG schematic values (poctop's 150k and a final 150k after the switch vs 400k and a 1M after the switch). Is this because voltage has been adjusted accordingly? I know the current drawn by the backplate of the capsule is almost nonexistent, which via Ohm's law leads to the necessity for high value resistors to induce a sufficient voltage drop.
How, then, do these resistors affect the voltage so dramatically? Shouldn't voltage drop mostly on the 30M resistor, leaving the change derived from the switched resistors negligible?
I know the macroscopic mechanisms of capsule polarization, specifically that it is a function of the potential difference between the backplate and the membrane, with 0V on the back membrane being cardioid and 120v being figure-eight, assuming 60v backplate.
Sorry if my questions are inane. Thanks for your help
