AC Power Connection

Because your Martin-Logan Logos uses an internal power
supply to energize its electrostatic cells with high-voltage
DC, it must be connected to an AC power source. For
this reason it is provided with the proper IEC standard
power cords. This cord should be firmly inserted into any
convenient AC wall outlet. The Logos has been designed
to remain on continuously and should remain connected
to a continuous AC power source. As mentioned earlier,
power consumption of the Logos is very small and the life
expectancy of its components will not be reduced by
continuous operation.

The power cord should not be installed, removed, or

connected to an AC power source.

Your Logos speaker is wired for the power service
supplied in the country of original consumer sale. The AC
power rating applicable to a particular unit is specified
both on the packing carton and on the serial number
plate attached to the speaker.

If you remove your Logos speaker from the country of
original sale, be certain that AC power supplied in any
subsequent location is suitable before connecting and
operating the speaker. Substantially impaired perform-
ance or severe damage may occur to the Logos if
operation is attempted from an incorrect AC power
source.

Signal Connection

Connections are done at the Signal Input

Signal Input section on the

back panel of the Logos. Use spade connectors for
optimum contact and ease of installation. Make certain
that your connections are tight.

Use the best speaker cable you can! The length and type
of speaker cable used in your system will have an audible
effect. Under no circumstance should a wire of gauge
higher (thinner) than #14 be used. In general, the longer
the length used, the greater the necessity of a lower
gauge, and the lower the gauge, the better the sound,
with diminishing returns setting in around #8 to #12.

A variety of speaker cables are now available whose
manufacturers claim better performance than with
standard heavy gauge wire. We have verified this in
some cases, and the improvements available are often
more noticeable than the differences between wires of
different gauge.
