ANALOG AUDIO INPUT DIGITAL THRU CONNECTOR LOUDSPEAKER CONNECTORS (ONLY USED WHEN THE AMPLIFIER IS MOUNTED SEPARATELY IN A RACK) Front Panel Light Functions Green light on the DCW panel of a 1237A or 1238A enclosure indicates normal operation. A yellow light indicates certain activities when the GLM control software is used. The light turns red in an overload condition. The overload light (red) is activated by several events: 1.
