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 Grotto is designed with a durable, stain-resistant
surface, we advise you not to set anything on your Grotto—
especially containers holding liquids.
Is there likely to be any interaction between my
subwoofer and the television in my Audio/ Video
system?
Yes. The Grotto subwoofer doesn’t use shielded drivers.
We recommend 3 feet between the Grotto subwoofer and
video components that are susceptible to magnetic fields.
Will my electric bill go 'sky high' by leaving my sub-
woofer plugged in all the time?
No. The Grotto, 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 power switch on the Grotto 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 Grotto and check the fuse near
the AC power cord receptacle on the back. If the fuse
has blown, replace it with a matching, 5 Amp slow-blow
fuse (3 Amp slow-blow 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
ETC spikes.
• Decrease the level.
• Decrease the 25Hz level.
• Check your processor setup.
• If the problem persists, contact your dealer.
Hums or Unusual Sounds
• Turn the Grotto off, unplug all signal inputs, turn the Grotto
back on and turn up the level. If the problem disappears,
the hum is originating elsewhere in your system.
• Connect the Grotto’s AC connection to the same AC circuit
as the pre amp.
• If the problem persists, contact your dealer.
