Yuken setting adjusters that supply the command-signal voltage to proportional-control power amplifiers. As setting depends on the actual operating method, setters are normally built to customer request; the following are sold as standard products. MC-01 is the simplest manual dial setter (single 1 kΩ volume); MC-02 is a centre-tapped manual dial setter (1 kΩ·1 kΩ) suited to servo systems; AMC-V6 is a 6-point setter for individual setting of six points.
