MTM - MTM is an extremely extensive modular range: it is furnished with modules that function on 5 different systems and that allow numerous functions to be performed. The basic design makes the external unit attractive on all surfaces and, at the same time, functional in daily use. The aluminium satin finishes ensure brightness and long duration, while the attention to the details enabled small refinements such as the elimination of the speaker holes and the dual colour backlighting of the keys.
