Owner's Manual
AC POWER SOCKET*
Supplies AC power to the PSB subwoofer. Connect the supplied 
power cord to the AC power socket. Plug the power cord into 
any standard wall outlet. The same receptacle as the rest of the 
system or another on the same electrical circuit should be used to 
avoid ground hum.
The PSB subwoofer has its own self-contained amplier and thus 
requires AC power (keep this in mind when selecting a location). 
You may plug the power cord into any standard wall outlet and 
leave the connection in the wall as the PSB subwoofer draws 
extremely little current when idle. If you are away for an extended 
period you may want to turn off the power switch or unplug your 
PSB subwoofer.
POWER SWITCH
The Power Switch turns off the subwoofer’s internal amplier.
AUTO STANDBY CONTROL SWITCH
Switching to Auto allows the sub to go into 0.5W Standby after 20 
minutes of inactivity.
EXTERNAL FUSE* 
When you turn on the subwoofer and there is no LED light and/or 
sound, please check the fuse (accessible from the rear panel) to 
ensure it is electrically intact. A spare fuse is contained within the 
fuseholder compartment behind the inscribed text. Use a wide slot 
screwdriver to pry the fuseholder compartment from the AC power 
socket. If it is necessary to replace the fuse, use a fuse equivalent 
to the type and rating of the fuse shipped with the product. See the 
specications page at the end of the manual for a detail description 
of the fuse required for your model of subwoofer.
*Not applicable on all models 
Note: On some models, the fuse has been mounted on the inside of the 
amplier panel. Removal of the amplier panel from the cabinet would be 
required in these cases. This should only be done at a PSB Service Center 
with the power cord disconnected.
