Frequently Asked Questions

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 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..
Plamsma, LCD, and LED television are not suceptible to
magnetic interference.
Is there likely to be any interaction between
my subwoofer and other electrical devices in
my house?
yes. When operating wirelessly this subwoofer may be
susceptible to RF interference in the 2.4GHz bandwidth
from microwave ovens and wireless devices such as
WiFi systems, video game consoles, cordless telephones,
blue tooth devices, and baby monitors. Generally, this
issue (intermittent sound or slight popping noises) is eas-
ily resolved by physically separating problematic devices
from one another—a distance as little as two feet will
often alleviate the interference. In the case of microwave
ovens, the interference will only occur when the micro-
wave is operating.
Will my electric bill go 'sky high' by leaving my
subwoofer plugged in all the time?
No. When the power switch is set to 'Auto On' the
subwoofer will draw about 15 watts when idle and only
1 watts in standby mode.
Should I unplug my subwoofer during a thun-
derstorm?
Yes, or before. It's a good idea to disconnect all of your
audio/video components during stormy weather.

Troubleshooting

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 'Auto On'.
• Check your wires and connections.
• Check all interconnecting cables.
• Make sure the level control is not turned down.
• Turn off and unplug the subwoofer 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
fuse.
• 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 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.
Intermitent Output With Wireless
• Make sure that no other wireless devices are within 2
feet of the SWT-2 transmitter.
• Check placement and make sure the SWT-2 wireless
transmitter is at least 1 foot off of the ground.
• Move the SWT-2 transmitter and sub closer together.
• Remove barriers from between the devices. Although
the SWT-2 uses an RF signal, it may not penetrate
some walls or cabinetry.
