Figure 1. CLX Controls and Connections
The power cords should be firmly inserted into the AC
power receptacle on the rear connection panel of the
CLX, then to any convenient AC wall outlet. Your CLX
speakers use an internal power supply to energize their
electrostatic panels and must be connected to an AC
power source with the proper IEC standard power cords.
CLX’s signal sensing power supply will switch off after 5
minutes of no signal, and requires less than four seconds
to recharge the panels when a music signal is present.
Your CLX speakers are wired for the power service
supplied in the country of original consumer sale. The
AC power rating for each unit is specified both on the
packing carton and on the speaker’s serial number plate.
If removed from the country of original sale, be certain
that the AC power supplied in any subsequent location
is suitable before connecting and operating the speakers.
Substantially impaired performance or severe damage
may occur to an CLX speaker if operation is attempted
from an incorrect AC power source.
WARNING! The power cord should not be
installed, removed, or left detached from the
speaker while the other end is connected to an
AC power source.
Signal Connection
Connections are made on the rear electronics panel of the
CLX. Use spade connectors for optimum contact and ease
of installation. Hand tighten the binding posts, taking care
to assign the same color cable lead to the (+) terminal on
both the left and right channel speakers. If bass is weak
and you cannot discern a tight, coherent image, you may
need to reverse the (+) and (–) leads on one speaker to
bring the system into proper polarity.
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 higher (thin-
ner) than #16 gauge be used. The longer the wire, the
greater the necessity of a lower gauge, and the lower the
gauge, the better the sound, with diminishing returns set-
ting in around #8 to #12.
WARNING! Turn your amplifier off before
making or breaking any signal connections!
Break-In
Proper break in will improve bass extension. The high
quality components used in our electrostatic panels may
cause your CLX speakers to sound a bit bass shy when
they are first used. CLX requires approximately 100 hours
of break-in at 90 dB (moderate listening levels) before any
critical listening. The break-in requirements of the cross-
over components are equivalent.
ML Logo and CLX Light Switches
The light control switches allow the illuminated
MartinLogan logo and CLX logo to be turned off or on.
