Operation

Understanding Cascading Input Jacks

MLT uses switched, or normalled, connections between some of its input jacks. With no cable inserted, a signal flows down from one input jack to another. This connection is overridden when a cable is inserted. Normalled inputs are indicated on the front panel with arrows.
