MartinLogan engineers designed the Depth for easy setup
and system integration. Before beginning to connect your
Depth, please review the controls discussed in the last sec-
tion. An understanding of these will help speed you along as
you connect your Depth with your system. All signal con-
nections are done at the signal input section on the rear
connections panel of the Depth. Make certain that all of
your connections are tight.
WARNING!
Turn your Depth subwoofer off
before making or breaking any signal connections!
2-Channel Mode
This setup is recommended if your Depth will be used in a
2-channel system with main speakers playing full range.
When a signal is connected to the Depth’s Left/Right Inputs,
the Depth’s internal low pass filter is active.
Signal Connection (see figure 2):
1 Connect the left and right outputs of your preamplifier to
the left and right inputs of the Depth using quality RCA
interconnects. If your preamplifier only has one set of out-
puts you may need to obtain Y adapters from your dealer.
Recommended Control Settings (see figure 3):
1 Set the 25Hz Level control to 0.
2 Set the low-pass filter switch to to the closest option equal
to 70% of your loudspeakers lowest frequency response.
3 While playing music with bass content, turn the level con-
trol 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 using the Depth to aug-
ment other MartinLogan products, we suggest you start
with the phase set at 90° (0° if you are using Script™
loudspeakers).
5 If you have completed steps 1–4 and still have weak or
boomy bass, adjust the 25Hz knob to compensate for
these anomalies. Turn the 25Hz control up and down and
listen to the effects that it has on the music. Try to find a
position that sounds correct to you. Experiment by chang-
ing the level control while adjusting this knob. You should
be able to find a position that gives you deep extended
bass and good blending with your main speakers.
