16 Frequently Asked Questions and Troubleshooting
FREQUENTLY ASKED QUESTIONS AND TROUBLESHOOTING
How do I clean my speakers?
Just use a dust free cloth or a soft brush to remove the dust
from your speakers. We recommend a specialty cloth
(available at the Xtatic shop at www.martinlogan.com)
that cleans your speakers better than anything else we
have tried. Do not spray any kind of cleaning agent
on or in close proximity to the ATF element.
What size amplifier should I use?
We recommend an amplifier with 100 watts per channel
for most applications. Probably less would be adequate
when used in home theater where a subwoofer is
employed. Our hybrid designs will perform well with
either a tube or transistorized amplifier, and will reveal
the sonic character of either type. However, it is impor-
tant that the amplifier be stable operating into varying
impedance loads: a stable amplifier will be able to
deliver twice its rated wattage into 4 Ohms and should
again double into 2 Ohms.
Could you suggest a list of suitable electronics and
cables that would be ideal for MartinLogan speakers?
The area of electronics and cable choice is probably
the most common type of question that we receive. It is
also the most subjective. We have repeatedly found that
brands that work well in one setup will drive someone
else nuts in another. We use many brands with great
success. Again, we have no favorites; we use electronics
and cables quite interchangeably. We would suggest
listening to a number of brands—and above all else—
trust your ears. Dealers are always the best source for
information when purchasing additional audio equipment.
Is there likely to be any interaction between my speak-
ers and the television in my Audio/Video system?
The MartinLogan Fresco loudspeaker is fully shielded
and can go anywhere.
Will exposure to sunlight affect the life or perfor-
mance of my speakers?
We recommend that you not place any loudspeaker in
direct sunlight. The ultraviolet (UV) rays from the sun can
cause deterioration of grill cloth, speaker cones, etc. Small
exposures to UV will not cause a problem. In general,
the filtering of UV rays through glass will greatly reduce the
negative effects.
