LOW-VOLTAGE (DC) POWER CONNECTION 
Your EM-ESL X 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 X 
speakers integrate a signal sensing circuit which will 
switch the EM-ESL X 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 X speakers are provided with a 
power supply for the power service supplied in the 
country of original consumer sale. The AC power 
requirements applicable to a particular unit is 
specified both on the packing carton and on the 
DC power supply.
If you remove your EM-ESL X 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 X speak-
er 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 
do not overtighten—do not use a tool to tighten the 
binding posts.
Be consistent when connecting the speaker cables 
to the signal input terminals. Take care to assign 
the same color cable lead to the (+) terminal on 
both the left and right channel speakers. If bass is 
nonexistent and you cannot discern a tight, coher-
ent image, you may need to reverse the (+) and 
(–) leads on one speaker to bring the system into 
proper polarity.
