INSTALLATION IN BRIEF
We know you are eager to hear your Script loudspeakers,
so this section is provided to allow fast and easy set up.
Once you have them operational, please take the time to
read, in depth, the rest of the information in this manual.
It will give you perspective on how to attain the greatest
possible performance from this most exacting transducer.
If you should experience any difficulties in the setup or
operation of your Scripts, please refer to the Installation or
Operation sections of this manual.
Should you encounter a persistent problem that cannot be
resolved, please contact your authorized MartinLogan
dealer. They will provide you with the appropriate technical
analysis to alleviate the situation.
WARNING!
•Hazardous voltages exist inside—do not
remove cover
•Refer servicing to a qualified technician
•To prevent fire or shock hazard, do not
expose this module to moisture
•Turn amplifier off and unplug speaker
should any abnormal conditions occur
•Do not operate if there is any visual
damage to the electrostatic panel element
•Do not over drive speaker beyond its rated power
Step 1: Unpacking
Remove your new Script speakers from their packing.
Step 2: Mounting
Mount each Script at its desired location on your front, side,
or back wall(s). Please see the Mounting the Script section
(pages 6–9) of this manual for details on installation and
determining the proper mounting height.
Step 3: Power Connection (AC) (see warning)
MartinLogan speakers require AC power to energize their
electrostatic cells. Using the AC power cords provided,
plug them in
first to the AC power receptacle on the rear
panel of the speaker
, making sure that you have made a
firm
connection, and then to the wall outlet. Please see the
Operations section (pages 5) of this manual for more details.
Step 4: Signal Connection
Use the best speaker cables you can. Higher quality cables,
available from your specialty dealer, are recommended
and will give you superior performance. Spade connectors
are suggested for optimum contact and ease of installation.
Attach your speaker cables to the Signal Input section on
the rear panel. Be consistent when connecting speaker
leads to the terminals on the back of the Script: take great
care to assign the same color to the (+) terminal on both
the left and right channels. If bass is nonexistent and you
cannot discern a tight, coherent image, you may need
to reverse the (+) and (-) leads on one side to bring the
system into proper polarity.
Please see the Operations section (pages 5) of this manual
for more details.
Step 5: Listen and Enjoy
Now, you may turn on your system and enjoy!

4 Introduction
INTRODUCTION
Congratulations! You have invested in one of the world’s
premier loudspeaker systems.
The MartinLogan Script represents the culmination of an
intensive, dedicated group research program directed
toward establishing a world class reference monitor
utilizing leading-edge technology, without compromising
durability, reliability, craftsmanship or aesthetic design.
The result of cumulative technology gleaned from previous
research and development projects, the Script represents
the latest developments in electrostatic and hybrid loudspeaker technology.
Combining our proprietary curvilinear electrostatic transducer with a compact, but powerful woofer, we have
designed a product, in one package, that reproduces music
with uncomprimised electrostatic clarity.
The materials in your new Script speakers are of the highest
quality and will provide years of enduring enjoyment and
deepening respect. The cabinetry is constructed from the
highest quality composite material for acoustical integrity and
is finished with our attractive custom matte finish.
Through rigorous testing, the curvilinear electrostatic panel
has proven itself to be one of the most durable and reliable
transducers available today. Fabricated from a custom tool
punched high-grade steel, the patented panel is then coated
with a special polymer that is applied via a proprietary
electrostatic deposition process. This panel assembly houses
a membrane just 0.0005 of an inch thick. Ruggedly constructed and insulated, as much as 150 watts of continuous
power has driven the Script’s energized diaphragm into
massive excursions with no deleterious effects.
The other sections of your User’s Manual will explain in
detail the operation of your Scripts and the philosophy
applied to their design. A clear understanding of your
speakers will insure that you obtain maximum performance and pleasure from this most exacting transducer. It
has been designed and constructed to give you years of
trouble-free listening enjoyment.
OPERATION
Operation 5
Because your Scripts use an internal power supply to energize their electrostatic cells with high-voltage DC, they must
be connected to an AC power source. For this reason they
are provided with the proper IEC standard power cords.
These cords should be firmly inserted into the AC power
receptacles on the rear connection panel of the speakers,
then to any convenient AC wall outlet. The Stript’s integrate
a signal sensing power supply which will switch 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 Scripts are 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 Scripts from the country of original
sale, be certain that 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 Script 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
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 speaker cables are now available whose
manufacturers claim better performance over 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 different gauge. The effects of
cables may be masked if the equipment is not the highest quality.
We also recommend, if possible, that short runs of speaker
cable connect the power amplifier(s) and speakers and that
high quality long interconnect cables be used to connect
the preamplifier and power amplifier. This results in the
power amplifiers being close to the speakers, which may
be practically or cosmetically difficult, but if the length of
the speaker cables can be reduced to a few meters, sonic
advantages may be obtained.
Connections are done at the Signal Input section on the
rear electronics panel of the Script. Use spade connectors
for optimum contact and ease of installation. Make certain
that all of your connections are tight. 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, coherent image,
you may need to reverse the (+) and (-) leads on one speaker
to bring the system into proper polarity. (See figure 1)
WARNING! Turn your amplifier off before making
or breaking any signal connections!
Break-In
When you first begin to play your Script speakers, they will
sound a bit bass shy. This is due to the high-quality, long-life
components used in our woofer. Our custom made, butyl
surround woofer requires 30 hours of break-in at 90 dB
(moderate listening levels) before any critical listening. The
break-in requirements of the crossover components (and, to
a lesser degree, the stator) are equivalent.

WARNING! Installing the Script on a wall
requires only 1 person, but an assistant can
be helpful.
NOTE: To assure that your Scripts are safely wall mounted,
these instructions must be carefully followed. Study them
thoroughly before beginning to install your Scripts.
NOTE: The following instructions assume the mounting
surface is of standard wood frame and standard sheet rock
construction. If you wish to mount the Script to another
type of material, you should consult a bonded contractor.
The functional Script wall bracket is designed to mount the
Script securely to your wall and allows the Script to pivot
on a nearly 180 degree axis for maximum versatility.
Before you begin to install your Scripts on a wall, prepare a
work area—either on a carpeted floor or on a sturdy tabletop
covered by a soft blanket or other cloth to prevent damaging
the speaker cabinet.
The Wall Mount Bracket
The functional Script wall bracket is designed to hold the
Script securely to your wall and allows the Script to swing
on a nearly 180 degree vertical axis for maximum versatility.
1 The Script is shipped with the wall bracket mounted on
and positioned to the side of the speaker cabinet, protected by micro-foam packing material. Set the Script on
its side with the bracket facing up. Loosen the knob on
the bottom and the knob on the top. Swing the bracket
down until the bracket is nearly parallel to the back of
the Script (see figure 2, step A).
2 Loosen and remove the knob on the bottom of the
speaker—notice that the 5/8 inch fiber washer and 1-
1
/2
inch diameter rubber spacer are shipped installed. The
fiber washer will come free when you remove the wing
nut—set the washer aside. Loosen and remove the knob
on top of the bracket while holding the bracket with
your free hand—set the fiber washer and 1-1/2 inch rubber spacer aside (see figure 2, step B).
3 Carefully pivot the top of the wall bracket away from
the Script until the wall bracket clears the top of the
speaker cabinet (see figure 2, step C). Next, move the
bracket down to free it from the threaded stud projecting
from the bottom of the speaker cabinet. Make sure that
the 1-1/2 inch spacer remains on the projecting threaded
stud (see figure 2, step D). Finally, remove the micro-foam
packing material.

MOUNTING THE SCRIPT
Mounting the Script 7
1 Mark a center point on the wall where you want to mount
the Script, 38 inches above the floor. This point is the
height recommended by MartinLogan to mount the Script
wall bracket and will be the location into which the
wall brackets upper mounting wall anchor and screw
are driven. You may choose to mount the Script higher or
lower—your seated ear level should be approximately
4 inches higher than the point that you just marked.
Make sure that the wall is clear of obstructions 6 inches to
the left and to the right of the center point, and from the
floor to 26 inches above the center point (see figure 3).
2 Use a hammer to tap a nylon wall anchor through the
center point and then drive the anchor all the way into
the wall by using a #2 Phillips bit and an electric drill
(see figure 3).
3 Mount the wall bracket to the wall by placing a #12 metal
washer on a screws and driving it through the hole at
the top-back of the wall bracket (the hole immediately
above the MartinLogan zig cutout) and into the center
point-mounting anchor. Do not tighten (see figure 3).
4 Allow the wall bracket to hang freely, and use a level to
assure the wall bracket is perfectly vertical (see figure 5).
Mark your second wall anchor location at the center of
the slot on the bottom-back of the wall bracket (the slot
immediately below the MartinLogan zig cutout). Pivot the
wall bracket to one side so that you can sink the wall
anchor into the location that you just marked. Use a
hammer to tap a nylon wall anchor through the center
point and then drive the anchor all the way into the wall
by using a #2 Phillips bit and an electric drill (see figure 4).

5 Move the wall bracket back into position over the wall
anchor and place #12 metal washer on one of the screws
and drive it through the slot at the bottom-back of the
bracket into the mounting anchor. Do not tighten (see
figure 5).
6 Use a level to assure that the wall bracket is perfectly
vertical, then securely tighten the screw at the bottom
of the wall anchor. Next, securely tighten the screw at
the top of the wall bracket (see figure 5).
WARNING! When pivoting the Script into place
in step 7, be careful so as not to damage the top
of the Script cabinet.
7 Check to make sure that a 1-
1
/2 inch rubber spacer is on
the threaded stud on the bottom of the speaker. Pick up
the speaker and carefully angle the bottom of the Script
into the bracket by inserting the projecting threaded stud
on the bottom of the speaker cabinet through the slot
in the bottom support of the wall bracket (see figure 6).
Figure 5. Figure 6.
Mounting the Script 9
8 Position a black rubber spacer over the threaded hole in
the top of the speaker cabinet and carefully pivot the top
of the Script into the wall bracket. Carefully move the
speaker cabinet so that the center of the rubber spacer,
the top-support hole, and the threaded hole on top of
the Script cabinet are aligned. You may find it helpful to
secure the rubber spacer over top of the wall brackets
top support hole with loosely applied masking tape that
you can easily remove once the knob is in place. Insert the
male threaded knob through a fiber washer, the wall
bracket and rubber spacer, and into the speaker cabinets
threaded hole (see figure 7).
9 Install the female knob on the bottom of the Script by
threading a fiber washer onto the threaded stud projecting
for the bottom of the speaker cabinet, then screwing the
female knob onto the threaded stud (see figure 7).
10 Your Script is no mounted on the wall (see figure 8). To
direct the speaker at the listening position, loosen the
top and bottom knobs slightly and pivot the speaker to
the optimum angle. Re-tighten the knobs.
