Frequently Asked Questions 17

Will excessive smoke or dust cause any prob-

lems with my electrostatic speakers?

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. When not in use for

extended periods, you should unplug the speakers and

cover them with the plastic bags in which the speakers

were originally packed. It is a good idea to vacuum

the electrostatic portion of each speaker three or four

times a year. See the vacuuming FAQ.

A problem has recently developed with my

MartinLogan speakers. The right speaker

seems to be hissing even when the amplifier

and such are not connected. I was wonder-

ing if this sounds like any problem you have

encountered previously and have a simple

solution for or might it be something which will

need to be looked into more carefully.

Your speakers are dusty. See the vacuuming FAQ. The

electrostatic charge on the element has attracted airborne

dust or pollen. Since 1993, all of our speakers have

been built with a charging circuit board that only charg-

es the electrostatic element when music plays. At other

times they are not charged and cannot collect dust. You

can get the same benefit by simply unplugging them

whenever they are not in use. A power strip is an easy

way to do that.

Could my children, pets, or myself be shocked

by the high-voltage present in the electrostatic

panel?

No. High voltage with low current is not dangerous.

As a matter of fact, the voltage in our speakers is 10

times less than the static electricity that builds up on the

surface of your television screen.

How do MartinLogan speakers hold up over a

long term in the humidity of tropical climates?

We should tell you that MartinLogan indeed has a very

substantial number of customers in tropical regions of

the world. Our speakers have been serving them nicely for

many years. This concern may have come from our earlier

design of speakers, which were charged continuously.

Since 1993, all of our speakers have been designed so

that they only charge the panel while music is being

played. This improvement has made a tremendous

difference in the consistent performance of our prod-

uct. There may be a little more maintenance involved

in humid regions when not in an air conditioned envi-

ronment. Simply enough, the concern is to keep the

electrostatic panels dust free. Humidity will combine

with any dust on the panel to make it slightly conduc-

tive. This will result in a slight pathway for the charge

to leave the membrane of the speakers. The solution is

simple. They only require occasional vacuuming with a

strong vacuum hose.

How do I vacuum my MartinLogan speakers?

Vacuuming will be most effective if the speakers have

been unplugged for six hours to twelve hours (or over-

night). You need not worry about the vacuum pressure

damaging the "delicate" membrane. It is extraordi-

narily durable. Dirt and dust may be vacuumed off with

a brush attachment connected to your vacuum cleaner,

or you may blow them off with compressed air. When

vacuuming or blowing off your panels do so to both

sides, but focus the majority of your attention on the

front of the panels.

Should I unplug my speakers during a thun-

derstorm?

Yes, or before. It’s a good idea to disconnect all of

your audio/video components during stormy weather.
