MartinLogan MLT-1 - Manual (Page 14)

13
Will my electric bill go 'sky high' by leaving my subwoofer plugged
in all the time?
No. The MLT-1 5.1 subwoofer, when the power switch is set to ‘Auto On’, will draw about
12 watts when idle and only 12 watts in standby mode.
Should I unplug my subwoofer during a thunderstorm?
Yes, or before. It's a good idea to disconnect all of your audio/video components during
stormy weather.
