Power Status Light
Your subwoofer is equipped with a multi-color LED to indicate the
current status of the subwoofer. This light is identical in function
to the Status light on the subwoofer's top panel. The following list
explains the meaning of the different colors:
No color: No power. The subwoofer is not plugged in or has
shutdown due to an overload condition. Unplug the subwoofer
and plug it back in to correct.
Green: Play mode. This indicates the subwoofer detects an
audio signal and has automatically switched into play mode.
Red: Standby. Your sub has switched into power saving mode.
