WARNING! Turn your amplifier
off before making or breaking any
signal connections!
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 on the rear panel of the
speaker. Use spade connectors for optimum con-
tact 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.
Take care to assign the same color cable lead to
the (+) terminal on both the left and right channel
speakers.

BREAK IN
Allow approximately 72 hours of break-in at 90
dB (moderate levels) before any critical listening.
COMPATIBILITY
The Motion AFX is designed to sit on top
of floorstanding and bookshelf speakers in
MartinLogan’s Motion series. At the time of this
manual’s publication these models include the
Motion 15, 20, 35XT, 40, and 60XT. The Motion
AFX will also work with other brands of speakers
with a relatively flat top. Note: The Motion AFX is
not recommended for use on top of MartinLogan’s
electrostatic speakers, as the electrostatic panels
will block the radiation of the AFX’s sound towards
the ceiling. The Motion AFX can be used with
electrostatic speaker if placed within 3 feet of the
electrostats and in such a way that their sound is
capable of radiating directly towards the ceiling.
