All electro-mechanical parts eventually wear down, and that holds true for the motorized faders in our X-TOUCH controllers – they undergo the wear and tear of heavy use. The MF100T is the same motorized 100 mm fader that came in your X-TOUCH or X-TOUCH COMPACT, making it the ideal replacement part for maintaining like-new functionality. The MF100T will extend the lifespan of your X-TOUCH for many more years of the flawless performance you’ve come to rely on.
