introduction and installation in Brief
Introduction
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 establishing a world class line of reference subwoofers using
leading-edge technology, without compromising durability, 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 finished 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 maximum performance and pleasure from this most exacting
subwoofer.
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.
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 transmitter. 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.
Installation in Brief
We know that you are eager to hear your new subwoofer,
so this section is provided to allow fast and easy
you have it operational, please take the time to
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 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.

aBout the controls
Level Knob
Setting the level too high will cause the bass to seem bloated 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 systems 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 processor 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 formula 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.

connections and control settings
Before Connecting the Dynamo
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 subwooferMake certain that all of your connections are tight.
WARNING! Turn your subwoofer to 'Off'
before making or breaking any signal connections!
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-frequency information, in addition to discrete LFE information,
through the LFE output.
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°.
Figure 2. Signal connection for 2-channel mode.
Signal Connection (see figure 2):
1 Connect the left and right outputs of your preamplifier
to the left and right inputs using quality RCA interconnects. 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
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.

Multi-Channel/LFE Mode
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 information, 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 processors, 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.
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
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-

AC Power Connection
WARNING! The power cord should not be
installed, removed, or left detached from
the subwoofer while the other end is connected 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 automatically 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 rating 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 attempted from an incorrect AC power source.
1. Press the subwoofer’s sync button and hold for 3 seconds. 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 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 microwave is operating.
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 listening 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.
10 Connections and Control Settings
Figure 6. Establishing a connection between the subwoofer and the
SWT-2 Subwoofer Wireless Transmitter (included).
Listening Position
Generally, subwoofers have the most output when placed
in the corner of a room. However, this can also exaggerate the subwoofers output making blending difficult. We
recommend starting by placing the subwoofer in a corner. 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.

Placement
Figure 7. Dynamo subwoofers as the LFE (effects) channels, MartinLogan
speakers as front, center, and surround (effects) channels. Note the corner
placement of the subwoofers at the front of the listening room.
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 measurable 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 recommended that there be a minimum of three inches of open
space between the cabinet and the front and back sides
(see figure 8).
