As well as standard audio and video cables, the Palmer Pro AHMCT XL also tests the major data cables (USB, RJ45). The test sequence can be either automated or manual, meaning the Pro AHMCT XL from Palmer is as ideal for the layperson as it is for the engineer. The sturdy metal housing with practical handle effortlessly withstands even the toughest on-stage demands. Yet despite its impressive array of functions, it remains sufficiently compact to fit in any professional workshop or well-equipped tool case.
