making it possible for us to do what we love.

6 Introduction and Installation in Brief
introduction and installation in Brief
Congratulations! You have invested in one of the
world's premier subwoofers.
The MartinLogan Dynamo 1000W and 700W
subwoofers represent the extension of an intensive,
dedicated team research program directed toward estab-
lishing a world class line of reference subwoofers using
leading-edge technology, without compromising durabil-
ity, reliability, craftsmanship or aesthetics.
These subwoofers use high-excursion drivers to achieve
deep, tight, well-defined bass. A proprietary amplifier is
used to drive the output stage with precision and extremely
high efficiency. Low-pass filtering and phase control have
been designed to make integrating the Dynamo 1000W
and Dynamo 700W subwoofers with MartinLogan and
non-MartinLogan products both seamless and simple.
The materials in your new subwoofer are of the highest
quality and will provide years of enduring enjoyment and
deepening respect. The cabinet is constructed from the
finest composite material for acoustical integrity and is fin-
ished with an attractive custom coating.
This User's Manual will explain in detail the operation of
your subwoofer and the philosophy applied to its design.
A clear understanding will insure that you obtain maxi-
mum performance and pleasure from this most exacting
subwoofer.
Installation in Brief
We know that you are eager to hear your new subwoofer,
so this section is provided to allow fast and easy set up. Once
you have it operational, please take the time to read, in depth,
the rest of the information in this manual. It will give you per-
spective on how to attain the greatest possible performance
from this most exacting subwoofer system.
If you experience any difficulties in setup or operation
of the subwoofer, please refer to the Placement, Room
Acoustics and Connections and Control Settings sections.
Should you encounter a persistent problem that cannot
be resolved, please contact your authorized MartinLogan
dealer. They will provide you with the appropriate techni-
cal analysis to alleviate the situation.
Step 1: Unpacking
Remove your new subwoofer from its packing.
Step 2: Placement
Ideally, place the subwoofer in a corner near the front of the
room. This is a good place to start. Please see the Placement
section (page 11) of this manual for more details.
Step 3: Signal Connection
The Dynamo 1000W and Dynamo 700W subwoofers
are provided with the SWT-2 subwoofer wireless trans-
mitter. We recommend using a physical wire connection
if possible. However, if ideal subwoofer placement is a
challenge the SWT-2 will provide a seamless wireless
connection with an extremely detailed and articulate bass
performance.
Use the best cables you can. High quality cables, available
from your specialty dealer, are recommended and will
give you superior performance.
Attach your preamplifier/processor outputs through cables
to the signal input area located on the subwoofer’s rear
panel. Please see the Connections and Control Settings
section (pages 8–10) of this manual for more details.
Step 4: Power Connection (AC) (see warning)
Make sure the level knob is set at 'Min'. Plug the
subwoofer into a wall outlet. Review the AC Power
Connection section (page 10) of this manual for more
details.
Step 5: Setting the Controls
Set the level knob to a medium volume position (12
o'clock). Set the power switch to ‘Auto On'.
Step 6: Listen and Enjoy
Now, you may adjust your system and enjoy!
Introduction

Level Knob
Setting the level too high will cause the bass to seem bloat-
ed and is the single most common cause of bad sounding
subwoofers. A rule of thumb is that the subwoofer should
not draw attention to itself, but should simply make the sys-
tems low end seem more extended and accurate.
Phase Control Switch
The phase control is entirely dependent on the size and
configuration of your listening environment, the placement
of the unit, and your seating arrangement. Due to the way
bass sound waves develop in different rooms, there is
no rule of thumb for setting phase. For instance, if your
room has a peak at the subwoofer crossover area, you
may wish to set the phase so the actual acoustic outputs
of the subwoofer and main speakers are out of phase.
Experiment, try different settings and be patient.
Crossover
When the subwoofer is connected in multi-channel mode
(via LFE), the crossover switch should be set to 'Bypass (LFE
In)' so that the low pass filter is not active and your proces-
sor handles the bass management.
When connected in 2-channel mode (via left/right input),
the crossover switch should be set to 'Variable (L&R In)' so
that the low-pass filter is active.
Low Pass Filter Knob
When the subwoofer is connected in multi-channel mode
(via LFE), the low pass filter is not active and your proces-
sor handles the bass management. When connected in
2-channel mode via its left/right input, the low-pass filter
is active.
As a general rule the low pass filter should be set equal
to approximately 70% of your speaker’s lowest frequency
response. Remember, this is a general rule. We advise
that once you try the recommended setting using the for-
mula above, you should try the surrounding settings to see
which sounds best.
Wireless Sync Button and Status LED (not shown above)
The wireless sync button is used to establish connection to
the SWT-2 MartinLogan Subwoofer Wireless Transmitter.
The Wireless status LED indicates the current status of the
wireless connection (see page 10 for further details).
Status LED (not shown above)
When the status LED (located on the back of the
subwoofer) is blue, the subwoofer is on. When the status
LED is red the subwoofer is in standby mode.
Master Power Switch (not shown above)
Located on the back panel of the subwoofer, the Master
Power switch must be set to 'Auto On' for the subwoofer
to operate. When set to 'Auto On' the subwoofer will
automatically enter a power saving mode when no audio
signal is detected. The subwoofer will automatically come
out of power saving mode when a signal is detected.

About the Controls 7
Figure 1. Dynamo 1000W and Dynamo 700W controls.

MartinLogan's engineering and design team developed
the Dynamo 1000W and Dynamo 700W subwoofers
for easy setup and system integration. Before beginning
to connect your subwoofer, please review the controls
discussed in the last section. An understanding of these
will help speed you along as you connect and integrate
your subwoofer with your system. All signal connections
are done on the rear connections panel of the subwoofer-
Make certain that all of your connections are tight.
WARNING! Turn your subwoofer to 'Off'
before making or breaking any signal con-
nections!
2-Channel Mode
This setup is recommended if your subwoofer will be used
in a 2-channel system with main speakers playing full
range. When a signal is connected via left/right inputs
and the crossover switch is set to 'Variable (L&R In), the
subwoofer's internal low pass filter is active.
If you will be using your system for both 2-channel and
multi-channel listening we recommend connecting the
subwoofer as recommended in 'Multi-Channel/LFE Mode'
on the next page. Some modern receivers and processors
allow users to route left and right channel low-frequen-
cy information, in addition to discrete LFE information,
through the LFE output.
Signal Connection (see figure 2):
1 Connect the left and right outputs of your preamplifier
to the left and right inputs using quality RCA intercon-
nects. If your preamplifier only has one set of outputs
you may need to obtain Y adapters from your dealer.
Recommended Control Settings (see figure 3):
1 Set the crossover switch to 'Variable (L&R In)' .
2 Set the 'Low Pass Filter' knob to approximately 70% of
your loudspeakers lowest frequency response.
3 While playing music with bass content, turn the level
control up until the music has deep extended bass,
being careful to avoid levels that become overwhelming.
4 Try the phase control in different settings until the
best blending is obtained. If you are augmenting
MartinLogan loudspeakers, we suggest you start with
the phase set at 90°.

Connections and Control Settings 9
This setup is recommended if your subwoofer will be used
in a dedicated home theater or multi-channel system. When
a signal is connected to the subwoofer’s LFE input, and the
crossover switch is set to 'Bypass (LFE In)' the internal low pass
filter is not active. By following this setup, you will allow your
processor to handle most of the bass management.
If you will be using your system for both 2-channel and
multi-channel listening we recommend using this setup
and connection method. Some modern receivers and
processors allow users to route left and right channel
low-frequency information, in addition to discrete LFE infor-
mation, through the LFE output.
Signal Connection (see figure 4):
1 Connect the LFE output of the processor to the LFE input
using a quality RCA interconnect.
WARNING!
Based on the performance of most proces-
sors, it is recommended that MartinLogan
center and effects type speakers not be run
in large, wide, or full range mode. Doing
so may potentially damage the speaker if
the processor attempts to drive the speaker
beyond its rated frequency range. This
warning also applies to products from other
manufacturers.
It is recommended to run center and effects
type speakers in limited or narrow mode.
Some processors have an option to route the LFE
channel to your main and/or surround speakers.
We recommend that you do not use this option.
Recommended Control Settings (see figure 5):
1 Set the crossover switch to 'Bypass (LFE In)' .
2 Use the bass management section of your processor‘s
speaker level setup option to set the subwoofer level at an
appropriate level. Follow the instructions in your processor
manual to fine-tune the subwoofer level.
3 If your processor offers the option to setup crossovers for a
subwoofer, we recommend that you start with the following
settings—Crossover: 70Hz, High-Pass: 12dB, and Low-
Pass: 24dB. The optimal setting for these options may vary
depending on your room and listening preferences.
4 Adjust the phase control until ideal blending is obtained. If
you hear no discernible difference leave the phase at 0°.
5 Follow the instructions in your processor manual to fine-
tune the subwoofer level

10 Connections and Control Settings
AC Power Connection
WARNING! The power cord should not be
installed, removed, or left detached from
the subwoofer while the other end is con-
nected to an AC power source.
The IEC power cord should be firmly inserted into the AC
power receptacle on the rear connection panel of the
subwoofer, then to any convenient AC wall outlet. The sub
also integrates a signal sensing power supply that automati-
cally switches off after sensing no music signal for several
minutes (this will occur when the power switch is set to 'Auto').
Your subwoofer is wired for the power service supplied in
the country of original consumer sale. The AC power rat-
ing applicable to a particular unit is specified both on the
packing carton and on the serial number plate attached to
the subwoofer.
If you remove your subwoofer from the country of original
sale, be certain that AC power supplied in any subsequent
location is suitable before connecting and operating the
subwoofer. Substantially impaired performance or severe
damage may occur to the subwoofer if operation is attempt-
ed from an incorrect AC power source.
Replacing the Fuse
If the fuse in your subwoofer should require changing, turn
off and unplug your subwoofer before removing the fuse.
Replace with a matching fuse.
Break-In
Our custom made woofers require approximately 50 hours
of break-in at moderate listening levels before their optimal
performance occurs. This will factor in on any critical listen-
ing and judgment.
Optional Wireless Connection
The Dynamo 1000W and 700W subwoofers incorporate
a wireless receiver for use with the MartinLogan SWT-2
Subwoofer Wireless Transmitter. To establish a wireless
connection, connect a transmitter to your electronics and
follow these two easy steps.
1. Press the subwoofer’s sync button and hold for 3 sec-
onds. The LED will blink quickly.
2 Press the sync button on the SWT-2 transmitter and hold
for 3 seconds. The LED will blink quickly. If pairing has
completed successfully both LEDs will stop blinking and
remain on. Please note: If a link is not established
after 30 seconds this transmitter’s LED will start blinking
slowly. Repeat both steps.
WARNING! For best performance we recommend that
the SWT-2 wireless transmitter not be placed on the floor.
WARNING! When operating wirelessly this subwoofer
may be susceptible to RF interference in the 2.4GHz
bandwidth from microwave ovens and wireless devices
such as WiFi systems, video game consoles, cordless
telephones, blue tooth devices, and baby monitors.
Generally, this issue (intermittent sound or slight popping
noises) is easily resolved by physically separating prob-
lematic devices from one another—a distance as little as
two feet will often alleviate the interference. In the case of
microwave ovens, the interference will only occur when
the microwave is operating.
Figure 6. Establishing a connection between the subwoofer and the
SWT-2 Subwoofer Wireless Transmitter (included).

Placement
Placement 11
Generally, subwoofers have the most output when placed
in the corner of a room. However, this can also exagger-
ate the subwoofers output making blending difficult. We
recommend starting by placing the subwoofer in a cor-
ner. If, after the full range of tuning techniques have been
employed, the subwoofer sounds like it has too much upper
bass energy try pulling it away from the wall, toward the
listening position. This will lessen the reinforcement of these
problematic frequencies from the wall and likely smooth out
the response. Repeat the tuning techniques with the woofer
controls after you move it (see figure 7).
Ask Your Dealer
Your MartinLogan dealer can suggest many options for
optimal subwoofer placement. They also have many tools
at their disposal, such as experience, familiarity with the
associated equipment, and even sound analysis equipment
which may make the task of determining optimal subwoofer
placement easier.
Enjoy Yourself
The Dynamo 1000W and Dynamo 700W are very
refined subwoofers and will benefit from care in setup.
With the above placement tips in mind you will find, over
months of listening, that small changes can result in mea-
surable differences. As you live with your subwoofer, do
not be afraid to experiment with positioning until you find
the optimal relationship between your room, settings and
subwoofer that gives you the best results. Your efforts will
be rewarded.
Installing in a Cabinet
When placing the subwoofer inside of a cabinet it is rec-
ommended that there be a minimum of three inches of open
space between the cabinet and the front and back sides
(see figure 8).
Listening Position

inches of open space on the front and back.

12 Placement
Changing Woofer Orientation
When installing the subwoofer in a cabinet it is recom-
mended that the subwoofer be converted to a front firing
configuration. (see figure 9).
1 Prepare a flat surface with a blanket to protect the finish.
Unplug signal and power connections. Remove the grill
cloth.
2 Carefully lay the subwoofer on its side. Using a coin,
unscrew the attached feet. (see figure 10).
3 Change the location of the four feet.
4 Using a coin, reinstall the feet (see figure 10).
Please note, 90° RCA adaptors may be required to
make signal connections. Two 90° RCA adaptors are
included with the subwoofer.
Figure 10. To change woofer orientation, use a coin to unscrew the
attached feet, change location, and reinstall.

room acoustics
Room Acoustics 13
This is an area that requires both a little background to
understand and some time and experimentation to attain
the best performance from your system. Your room is actu-
ally a component and an important part of your system.
This component is a large variable and can dramatically
add to or subtract from a great sonic experience.
All sound is composed of waves. Each frequency has its
own wave size, with the lower, or bass frequencies literal-
ly encompassing from 10 feet to as much as 40 feet. Your
room participates in this wave experience like a swim-
ming pool with waves reflecting and becoming enhanced
depending on the size and shape of the room and the
types of surfaces in the room.
Remember that your audio system can actually generate all
of the information required to recreate a sonic event in time,
space, and tonal balance. Acoustically, the role of an ideal
room would be to neither delete nor contribute to that infor-
mation. However, nearly every room does to some degree.
Terminology
Standing Waves
Sound coming from a speaker bounces around in a room
until a pattern emerges—this is called a standing wave.
Typically, this is only a problem with frequencies below
100Hz. When this happens different parts of your room
experience either an excess or a lack of bass.
Some people believe that having a room without parallel
walls will eliminate this effect. The truth is that non-parallel
walls only generate different standing wave patterns than
those that occur in rectangular rooms.
Usually, you can excite most of the standing waves in
a room by putting the subwoofer in a corner. Listening
position determines which standing waves you will expe-
rience. For instance, if you sit in a corner you will hear
most of the standing waves. This can be an overpowering
experience. Sitting next to a wall can also intensify the
levels of the standing waves that are experienced.
Resonant Surfaces and Objects
All of the surfaces and objects in your room are subject to
the frequencies generated by your system. Much like an
instrument, they will vibrate and "carry on" in syncopation
with the music, and may contribute in a negative way to
the sound. Ringing, boominess, and even brightness can
occur simply because surfaces and objects are "singing
along" with your speakers.
Resonant Cavities
Small alcoves or closet type areas in your room can be
chambers that create their own "standing waves" and can
drum their own "one note" sounds.
Solid Footing
After living and experimenting with your subwoofer,
you may want to use ETC™ (Energy Transfer Coupler)
Spikes (see figure 11). With the use of these spikes,
the subwoofer will become more firmly planted on the
floor and, consequently, bass will tighten. It is best not
to implement the spikes, however, until you are secure in
the positioning, as the spikes can damage the floor if the
subwoofer is moved.
Spike Installation Instructions:
1 Carefully lay the subwoofer on its side to gain access
to the bottom of the feet.
2 Firmly press the spikes into the feet.
Caution: Make sure your hands and any cabling are
clear of the spikes. Do not slide the subwoofer as spikes
are sharp and can damage your floor or carpet.

14 Home Theater
home theater
It had long been the practice of stereo buffs to connect their
television to a stereo system. The advantage was the use
of the larger speakers and more powerful amplifier of the
stereo system. Even though the sound was greatly improved, it
was still mono and limited by the broadcast signal.
In the late 1970’s and early 1980’s two new home
movie formats became widely available to the public:
VCR and laser disc.
By 1985, both formats had developed into very high quality
audio/video sources. In fact, the sonic performance of some
video formats exceeded audio-only formats. Now, with
theater-quality sound available at home, the only element
missing was the "surround sound" presentation found in
movie houses.
Fortunately, Dolby and DTS encoded DVD’s emerged
with the same surround sound information encoded on
home releases as the theatrical release. Additionally,
new high-resolution home-viewing formats such as Blu-ray
as well as high-definition content provided via cable or
satellite have evolved which include multi-channel encod-
ed audio that is virtually master tape quality. All that is
required to retrieve this information is a decoder and addi-
tional speakers and amps to reproduce it.
Home theater is a complex purchase and we recommend
that you consult your local MartinLogan dealer, as they
are well versed in this subject.
Each piece of a surround system can be purchased sepa-
rately. Take your time and buy quality. No one has ever
complained that the movie was too real. The following list
and descriptions will give you only a brief outline of the
responsibilities and demands placed on each speaker.
Front Left and Front Right
If these speakers will be the same two used for your stereo
playback, they should be of very high quality and able to play
loudly (over 102 dB) and reproduce bass below 80 Hz.
Center Channel
This is the most important speaker in a home theater
system, as almost all of the dialogue and a large por-
tion of the front speaker information is reproduced by the
center channel. It is important that the center speaker
be extremely accurate and mate well with the front
speaker, and that it is recommended for use as a center
speaker. This is not the place to cut corners.
Surround Speakers
We recommend (along with the film industry) that the sur-
round speakers play down to at least 80 Hz. Surround
speakers contain the information that makes it appear that
planes are flying over your head. Some may suggest that
this is the place to save money and purchase small, inex-
pensive speakers. If you choose to do so, be prepared
to upgrade in the future as discrete multi-channel digital
encoding is proliferating rapidly and the demands on sur-
round speakers have increased.
Subwoofer
With any good surround system you will need one or
more high-quality subwoofers (the .1 in a 5.1, 6.1, or 7.1
channel surround system). Most movie soundtracks contain
large amounts of bass information as part of the special
effects. Good subwoofers will provide a foundation for the

Frequently Asked Questions
Frequently Asked Questions & Troubleshooting 15
How do I clean my subwoofer?
Use a dust free cloth or a soft brush to clean your subwoofer.
We recommend a specialty cloth (available through the
Xtatic shop at www.martinlogan.com) that cleans better than
anything else we have tried.
Is it safe to set things on my subwoofer?
While your subwoofer is designed with a durable, stain-
resistant surface, we advise you not to set anything on your
subwoofer—especially containers holding liquids.
Is there likely to be any interaction between
my subwoofer and the television in my Audio/
Video system?
Yes. The subwoofer doesn’t use a shielded driver. We
recommend 3 feet between the subwoofer and video
components that are susceptible to magnetic fields..
Plamsma, LCD, and LED television are not suceptible to
magnetic interference.
Is there likely to be any interaction between
my subwoofer and other electrical devices in
my house?
yes. When operating wirelessly this subwoofer may be
susceptible to RF interference in the 2.4GHz bandwidth
from microwave ovens and wireless devices such as
WiFi systems, video game consoles, cordless telephones,
blue tooth devices, and baby monitors. Generally, this
issue (intermittent sound or slight popping noises) is eas-
ily resolved by physically separating problematic devices
from one another—a distance as little as two feet will
often alleviate the interference. In the case of microwave
ovens, the interference will only occur when the micro-
wave is operating.
Will my electric bill go 'sky high' by leaving my
subwoofer plugged in all the time?
No. When the power switch is set to ‘Auto On’ the
subwoofer will draw about 15 watts when idle and only
1 watts in standby mode.
Should I unplug my subwoofer during a thun-
derstorm?
Yes, or before. It's a good idea to disconnect all of your
audio/video components during stormy weather.
No Output
• Check that all your system components are turned on.
• Check that the master power switch adjacent to the AC
receptacle is set to 'Auto On'.
• Check your wires and connections.
• Check all interconnecting cables.
• Make sure the level control is not turned down.
• Turn off and unplug the subwoofer and check the fuse
near the AC power cord receptacle on the back. If the
fuse has blown, replace the bad fuse with a matching
fuse.
• If the problem persists, contact your dealer.
Muddy Bass
• Check placement. Try moving the subwoofer closer to
the front and side walls.
• Check the type of feet that are being used. Try installing
the ETC spikes.
• Decrease the level.
• Check your processor setup.
• If the problem persists, contact your dealer.
Hums or Unusual Sounds
• Turn the subwoofer off, unplug all signal inputs, turn the
subwoofer back on and turn up the level. If the problem
disappears, the hum is originating elsewhere in your
system.
• Connect the subwoofer’s AC connection to the same AC
circuit as the pre amp.
• If operating in wireless mode, move the subwoofer
away from microwave ovens and/or any devices that
use wireless technology.
• If the problem persists, contact your dealer.
Intermitent Output With Wireless
• Make sure that no other wireless devices are within 2
feet of the SWT-2 transmitter.
• Check placement and make sure the SWT-2 wireless
transmitter is at least 1 foot off of the ground.
• Move the SWT-2 transmitter and sub closer together.
• Remove barriers from between the devices. Although
the SWT-2 uses an RF signal, it may not penetrate
some walls or cabinetry.

If you did not receive a Certificate of Registration with your
new subwoofer you cannot be assured of having received
a new unit. If this is the case, please contact your autho-
rized MartinLogan dealer.
Should you be using your MartinLogan product in a country
other than the one in which it was originally purchased,
we ask that you note the following:
1 The appointed MartinLogan distributor for any given
country is responsible for warranty servicing only on units
distributed by or through it in that country in accor-
dance with its applicable warranty.
2 Should a MartinLogan product require servicing in a
country other than the one in which it was originally
purchased, the end user may seek to have repairs per-
formed by the nearest MartinLogan distributor, subject
to that distributor's local servicing policies, but all cost
of repairs (parts, labor, transportation) must be born by
the owner of the MartinLogan product.
3 If, after owning your subwoofer for six months, you relocate
to a country other than the one in which you purchased
your subwoofer, your warranty may be transferable.
Contact MartinLogan for details.
