Automatic timed power on / off
This subwoofer amplifier has an automatic audio signal detection system. When the switch is set to
"AUTO", the sub will turn on immediately when an audio signal is detected at the input. In "ON" mode, the
detector is inactive and the subwoofer remains permanently on. On the other hand, if no signal is detected
coming into the subwoofer after approximately 15 minutes, the detection system will automatically place
the subwoofer in stand-by mode. In the event of prolonged absence for several days, we recommend
turning the power switch to "OFF". In the event of a storm, unplug the mains cable.

features are simultaneously achieved.
