Setting the AUTO switch to ON automatically turns the
subwoofer on when a signal is detected at any of the inputs and
turns it off (Standby Mode) after a period of inactivity. We

operational. If your subwoofer is disconnected from the mains
or the Power switch is “Off”, the indicator will be extinguished.
