30     Frequently Asked Questions and Troubleshooting

Use a dust free cloth or a soft brush to clean your 
subwoofer. We recommend a specialty cloth (available 
through the Xtatic shop at www.martinlogan.com) that 
cleans better than anything else we have tried.

While your subwoofer is designed with a durable, stain-
resistant surface, we advise you not to set anything on 
your subwoofer—especially containers holding liquids.

Yes. The subwoofer doesn’t use a shielded driver. We 
recommend 3 feet between the subwoofer and video 
components that are susceptible to magnetic fields.
Plasma, LCD, and LED television are not susceptible to 
magnetic interference.

No. When the power switch is set to ‘Auto’ the subwoofer 
will draw about 15 watts when idle and only 10 watts in 
standby mode. 

Yes, or before. It's a good idea to disconnect all of your 
audio/video components during stormy weather. 

•  Check that all your system components are turned on.
•  Check your wires and connections.
•  Check all interconnecting cables.
•  Make sure the level control is not turned down.
•  If the problem persists, contact your dealer.

•  Check placement. Try moving the subwoofer closer to 

the front and side walls.

•  Check the type of feet that are being used. Try install-

ing the ETC spikes.

•  Decrease the level.
•  Check your processor setup.
•  If the problem persists, contact your dealer.

•  Turn the subwoofer off, unplug all signal inputs, turn the 

subwoofer back on and turn up the level. If the problem 
disappears, the hum is originating elsewhere in your 
system.

•  Connect the subwoofer’s AC connection to the same 

AC circuit as the pre amp.

•  If operating in wireless mode, move the subwoofer 

away from microwave ovens and/or any devices that 
use wireless technology.

•  If the problem persists, contact your dealer.
