How do I clean my subwoofer?
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.
Is it safe to set things on my subwoofer?
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.
Is there likely to be any interaction between my
subwoofer and the CRT television in my Audio/ Video
system?
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.
Will my electric bill go 'sky high' by leaving my subwoofer
plugged in all the time?
No. The subwoofer, when the power switch is set to
‘Auto’ or ‘Standby’, will draw about 30 watts when idle.
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.
No Output
• Check that all your system components are turned on.
• Check that the master power switch adjacent to the AC
receptacle is set to 'On'.
• Check that the power switch on the subwoofer is set to
either 'Auto' or 'On'.
• Check your wires and connections.
• Check all interconnecting cables.
• Make sure the level control is not turned down.
• Turn off and unplug the Descent i and check the fuse
near the AC power cord receptacle on the back. If the
fuse has blown, replace the bad fuse with a matching
T 10A H 250V fuse (T 5A L H 250V if you are in a region
using 230v–240v current).
• If the problem persists, contact your dealer.
Muddy Bass
• Check placement. Try moving the subwoofer closer to
the front and side walls.
• Check the type of feet that are being used. Try installing
the ETC spikes.
• Decrease the level.
• Check your processor setup.
• If the problem persists, contact your dealer.
Hums or Unusual Sounds
• 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 the problem persists, contact your dealer.
