Troubleshooting the Acoustic Research S112PS Subwoofer
|Why does the subwoofer POWER indicator LED light does not light Acoustic Research S112PS ?
Check that the Subwoofer's power switch is in the auto-on position.
If the power switch is in the AUTO ON position check the AC outlet the subwoofer is plugged into to be sure that it is live. Use a lamp or tester to test the outlet.
If the AC outlet is live, either the power cord or the subwoofer has a problem. Unplug the power cord from the Ac outlet and check the fuse by unscrewing the center piece from the holder. If it is blown replace the fuse only with a fuse of the same type and rating. If this doesn't help the unit needs service. There are no user serviceable parts inside.

|What do I do if the power is on, but the Acoustic Research S112PS subwoofer has stopped working?
- Be sure there is sound from the front speakers and that the receiver is hooked up correctly.
- Check the subwoofer's level control. If it is all the way counterclockwise there may be no sound.
- The subwoofer only reproduces deep base sound. If the program being played has no deep bass there will be no sound from the subwoofer. Play a program with plenty of bass to test.
