WARNING! The Summit features a down-firing woofer on the bottom of the cabinet. Setting the Summit flat on the
floor without the feet installed can damage this woofer. For this reason the Summit ships from the factory with the feet
installed. If, for some reason, you need to remove the Summit’s factory installed feet, carefully place the Summit on its
side until the feet are replaced. The down-firing woofer on the Summit requires at least 2 inches of clearance from the
floor for optimal performance. The Summit’s factory installed feet are specifically engineered to meet this requirement.
WARNING! Do not use your Summit loudspeakers outside of the country of original sale—voltage requirements
vary by country. Improper voltage can cause damage that will be potentially expensive to repair. The Summit is
shipped to authorized MartinLogan distributors with the correct power supply for use in the country of intended
sale. A list of authorized distributors can be accessed at www.martinlogan.com or by emailing info@martinlogan.com.

6 Introduction
Light Knob
The light control knob allows
the brightness of the illuminated strip to be adjusted.
25Hz Level Knob
The 25Hz Level knob significantly adjusts the level
between 20 and 30Hz by
±10dB. This is an area where
peaks and dips of different
amplitudes often manifest in
real environments. This setting is dependent on room
size and construction, system
configuration and personal
preference.
ESL Signal Input
This set of binding posts provides a place to connect the
signal that drives the XStat™
ESL transducer.
Woofer Signal Input
This set of binding posts provides a place to connect
the signal that drives the
PoweredForce™ woofers.
CONTROLS AND CONNECTIONS
50Hz Level Knob
The 50Hz Level knob significantly adjusts the level
between 40 and 60Hz by
±10dB. This is an area where
peaks and dips of different
amplitudes often manifest in
real environments. This setting is dependent on room
size and construction, system
configuration and personal
preference.
Status Light
The Summit is equipped with a
multi-color LED to indicate the
current status of the woofers.
The following list explains the
meaning of the different colors:
No color: No power. The
Summit is not plugged in.
Green: Play mode. This indicates the Summit detects an
audio signal and has automatically switched into play
mode.
Yellow: Standby mode. This
indicates the Summit has
detected no audio signal for
approximately 5 minutes and
has automatically switched
into standby mode.
AC Power Connection
Because your MartinLogan
Summit speakers use an internal power supply to energize
their electrostatic cells, they
must be connected to an AC
power source.
Red: Initializing or Safe mode.
This indicates that the Summit
is initializing. This also indicates
if the Summit’s temperature has
exceeded nominal operating
range. If the Summit overheats,
please allow the Summit to
cool and reset it by unplugging
the unit and plugging it back in.

Controls and Connections 7
AC Power Connection
Because your Summit speakers use an internal power
supply to energize their electrostatic cells and to power
the PoweredForce™ woofers, 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 Summit’s integrate a signal
sensing power supply which will switch off after five minutes of no music signal, and requires less than two seconds
to recharge the panels when a music signal is present.
Your Summit speakers 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 Summit speakers 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 Summit
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 cables are available whose
claim better performance than standard heavy gauge wire.
manufacturers
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 equipment is not of the highest quality.
Connections are done at the signal input section on the
rear electronics panel of the Summit. 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, coherent image, you may need to reverse
the (+) and (–) leads on one speaker to bring the system
into proper polarity.
WARNING! Turn your amplifier off before
making or breaking any signal connections!
Break-In
When you first begin to play your Summit 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 approximately
72 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.
Jumper Clips
In some countries federal law prohibits MartinLogan from
supplying jumper clips. If none are found installed under
your speakers binding posts, please refer to ‘Bi-Wire
Connection’ for connection instructions.
8 Controls and Connection
Single Wire Connection
Bi-Amplification
Please take note of the jumper clips installed under the
binding posts. These clips attach the high and low frequency sections of the crossover together. Leaving these
in place, connect the (+) wire from your amplifier to
either red binding post and the (–) wire from your amplifier to either black binding post (see figure 2).
Bi-Wire Connection
Bi-wiring the Summit is not necessary. The Summit is provided with a bi-wiring option to allow consumers who
already own quality bi-wire cables to use their existing
cables. This connection method replaces the jumper clips
installed
speaker wire from your amplifier. This doubles the signal
carrying conductors from the amplifier to the speaker, thus
direct-coupling each portion of the crossover to the amplifier.
First you must remove the jumper clips. Connect one set
of wires to the upper set of ESL binding posts. Next, connect a second set of wires to the lower woofer binding
posts. Finally, connect both sets of wires to the appropriate terminals on your amplifier. Please take care to
connect both (+) wires to the (+) amplifier terminals and
both (–) wires to the (–) amplifier terminals. This is also
known as a parallel connection (see figure 3).
under the binding posts with individual runs of
The Summit’s PoweredForce™ woofers are internally
powered. Because of this, we do not recommend either
active or passive bi-amplification.
25Hz and 50Hz Level Control
After you have determined the speaker position and primary listening position (see pages 11–12) you will want to
adjust the 25Hz and 50Hz level controls
On the rear of the Summit are two knobs that control
the 25Hz and 50Hz frequency responses by ±10db.
MartinLogan engineers have found this frequency area
(20–75Hz) to be problematic. Low frequencies tend to
react to a room environment by creating nodes (boomy
and unnatural bass) or nulls (nonexistent bass). By adjusting the 25Hz and 50Hz level knobs you can ‘dial out’
undesirable nodes or nulls and create a balanced and
seamless presentation.
To help find the optimal setting for your room, play material with (which you are familiar) with low frequency
information (such as a drum or a pipe organ). When
adjusting the 25Hz and 50Hz levels we recommend doing
so with two or three people—one located at the listening
position and one or two people at the controls.
