[ How to specify different output-law in multiple circuits ] * The number in front of CP2500 is the total number of circuits. * The first output-law specified in the beginning will be the knob side. * Consecutive cases of the same output-law are combined into one. ( A10K / A10K >>>> 2-A10K ) * Taper-A and Taper-B and Taper-C: Please see "Potentiometer CP2500 Series. * If the total resistance is different, specify it separately. * The CP2511 Series cannot be mounted because the angle is different. [Please refer to the following] |
