18 Frequently Asked Questions & Troubleshooting
FREQUENTLY ASKED QUESTIONS & TROUBLESHOOTING
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 is designed with a durable, stain-resis-
tant surface, we advise you not to set anything on your
Dynamo—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 subwoofer doesn’t use a shielded driver.
We recommend 3 feet between the Dynamo 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 Dynamo, when the power switch is set to ‘Auto’
or ‘Standby’, will draw about 13 watts when idle.
Should I unplug my subwoofer during a thunder
-
storm?
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 Dynamo 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 Dynamo 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 2A L 250V fuse (T 1A L 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 Mini ETC spikes.
• Decrease the level.
• Check your processor setup.
• If the problem persists, contact your dealer.
Hums or Unusual Sounds
• Turn the Dynamo off, unplug all signal inputs, turn the
Dynamo back on and turn up the level. If the problem
disappears, the hum is originating elsewhere in your
system.
• Connect the Dynamo’s AC connection to the same AC
circuit as the pre amp.
• If the problem persists, contact your dealer.
