* Replacing it from other brands tests it enough, and please consider.
* Caution in Ladder circuit use.

   Important points in using audio curve and log curve of TKD faders >>
* If distortion rate is a concern, consider the potentiometer circuit type.

Custom model number
[ How to specify different output-law in multiple circuits ]
* The number in front of CP2511 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 )
* If the total resistance is different, specify it separately.
* The CP2500 Series cannot be mounted because the angle is different.
