Before Connecting the Dynamo
6 Connections and Control Settings

MartinLogan's engineering and design team developed
the Dynamo 1000 for easy setup and system integra-
tion. Before beginning to connect your Dynamo 1000,
please review the controls discussed in the last section.
An understanding of these will help speed you along as
you connect and integrate your Dynamo 1000 with your
system. All signal connections are done on the rear con-
nections panel of the Dynamo 1000. Make certain that
all of your connections are tight.
WARNING! Turn your Dynamo 1000
subwoofer to 'Off' before making or
breaking any signal connections!
2-Channel Mode
This setup is recommended if your Dynamo 1000 will be
used in a 2-channel system with main speakers playing
full range. When a signal is connected to the Dynamo
1000’s left/right inputs and the crossover switch is set to
'Variable (L&R In), the Dynamo 1000’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
Dynamo 1000 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 infor-
mation, 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 of the Dynamo 1000 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 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°.
