What's the function that suppresses the torque of the channel rotary fader knob?

The channel rotary fader knob uses a unique mechanism that suppresses the load torque when the knob is turned at a certain speed or higher.

When turning it at low speeds, you can make delicate adjustments with a soft texture, and at high speeds, you can make dynamic adjustments that instantly reach the target volume, allowing you to perform a variety of techniques, from long mixes to short mixes. This provides the best operation feeling.

The Master Isolator knob and Master Level knob employ a mechanism in which the load torque is proportional to the knob operation speed, achieving the optimal operation feeling for each knob.
