Sporting the classic glass faceplate so familiar to McIntosh lovers, the MX406 is a reference control center, providing the traditional volume and balance functions as well as full changer controls and a large blue fluorescent information panel. Mounted in a car's dashboard, the MX406 brings the instant look of class, as well as familiar touches like the rotary volume control and analog bass and treble controls. The total performance in a car audio system depends upon the individual performance of each of its components.
