Unfortunately the most often asked question regarding
amplification is the most difficult to answer and that is
“How much power do I need?” The best advice we can
offer is that you consider that video is very dynamic and
the peak energy demands can last much longer than in
most musical presentations. Therefore it is our recom-
mendation that your A/V amplifiers be at least as large if
not larger than your current audio amplifier.
As for how much power should be available to each
channel compared to the others it is our feeling that the
front three speakers should receive the same amount of
power and the surround speakers at least 75% of the
power available to the front speakers . As discrete digital
surround becomes available all five speakers should
receive the same amount of power.

Yes. Or before. It’s a good idea to disconnect all of your
audio/video components during stormy weather.

Actually, there is less interaction between a television and
an electrostatic speaker than between a television and a
conventional system. The magnets in conventional
speakers do interact with televisions tubes. However, in
the Logos the conventional drivers' magnetic structure
has been physically shielded and the crossover has been
electrically shielded, so there will be no interference with
your television.

Our research department has literally punctured hun-
dreds of holes in a diaphragm, neither affecting the
quality of the sound nor causing the diaphragm to rip.
However, you may be able to see the actual puncture
and it can be a physical nuisance. If this is the case,
replacing the electrostatic transducer will be the only
solution.

Your Logos is equipped with a device we call the signal
sensing circuit. Here's how it works. The signal automati-
cally diminishes the bias voltage of the ESL cell to
conserve energy and prolong the life of the system. If you
like, you can think of it as an attendant who turns off the
lights when you aren't using them. Your Logos doesn't
use much energy anyway (it may cost you about as much
to operate as one 15 watt light bulb) but after five minutes
of the absence of any program material, the circuit will
turn it off.

We recommend that you not place any loudspeaker in
direct sunlight as the ultraviolet (UV) rays from the sun
can cause deterioration of grill cloth, speaker cones, etc..
Exposures through glass will not cause a problem,
however the heat generated by the sun will age the finish
on the speaker as it would any fine furniture. Martin-
Logan speakers are not recommended for outdoor use.

Exposure to excessive contaminants, such as smoke or
dust, may potentially affect the performance of the
electrostatic membrane and may cause discoloration of
the diaphragm membrane.
