LOW-VOLTAGE (DC) POWER CONNECTION

Your EM-ESL C speakers use external low-voltage
power supplies to energize their electrostatic pan-
els. For this reason the proper low-voltage power
supplies are provided. A power supply should be
firmly inserted into the 'DC Power In' receptacle on
the rear connection panel of each speaker, then
to any convenient AC wall outlet. Your EM-ESL C
speakers integrate a signal sensing circuit which will
switch the EM-ESL C off after a few minutes of no
music signal, and requires less than two seconds to
recharge the panels when a music signal is present.
Your EM-ESL C speakers are provided with a power
supply for the power service supplied in the country
of original consumer sale. The AC power require-

ments applicable to a particular unit is specified both
on the packing carton and on the DC power supply.
If you remove your EM-ESL C speakers from the
country of original sale, be certain that the AC
power supplied in any subsequent location is suit-
able before connecting the low-voltage power
supply. Substantially impaired performance or
severe damage may occur to a EM-ESL C speaker
if operation is attempted from an incorrect AC
power source.
WARNING! The DC power
supply should not be installed,
removed, or left detached from
the speaker while connected to an
AC power source.
SPEAKER LEVEL CONNECTION
Use the best speaker cables 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 #16
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 cables are available whose manufactur-
ers claim better performance than standard heavy
gauge wire. We have verified this in many cases,
and the improvements available are often more
noticeable than the differences between wires of dif-
ferent gauge. The effects of cables may be masked
if equipment is not of the highest quality.
Connections are done at the signal input section
on the rear electronics panel of the speaker. Use
spade connectors for optimum contact and ease
of installation. Hand tighten the binding posts, but
