Frequently Asked Questions
Frequently Asked Questions & Troubleshooting 15
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 Dynamo 1000 is designed with a durable, stain-
resistant surface, we advise you not to set anything on your
Dynamo 1000—especially containers holding liquids.
Is there likely to be any interaction between
my subwoofer and the television in my Audio/
Video system?
Yes. The Dynamo 1000 subwoofer doesn’t use a shield-
ed driver. We recommend 3 feet between the Dynamo
1000 subwoofer and video components that are suscep-
tible to magnetic fields..
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
(popping noises) is easily resolved by physically separat-
ing 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 microwave is operating.
Will my electric bill go 'sky high' by leaving my
subwoofer plugged in all the time?
No. The Dynamo 1000, when the power switch is set to
‘Auto On’, 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.
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 Dynamo 1000 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 5A L 250V fuse (T 2.5A L 250V if you are in a region
using 230V).
• 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 Dynamo 1000 off, unplug all signal inputs,
turn the Dynamo 1000 back on and turn up the level.
If the problem disappears, the hum is originating else-
where in your system.
• Connect the Dynamo 1000’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.
