Connections and Control Settings 9
This setup is recommended if your Depth will be used in a
2-channel only system. 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 8):
1 Connect the left and right outputs of your amplifier to
the left and right speaker level (high level) inputs of the
Depth using quality speaker cable.
If your amplifier only has one set of outputs you may
connect your amplifier to your speakers as normal and
run an additional set of cables from your speakers to the
Depth’s left and right speaker level (high level) inputs.
It is also possible to connect the left and right outputs of
your amplifier to the left and right speaker level (high
level) inputs of the Depth and run an additional set of
cables from your Depth to the speakers.
Recommended Control Settings (see figure 9):
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.
