We know you are eager to hear your new MartinLogan subwoofer, so
this section is provided to allow fast and easy set up. Once you have
your subwoofer operational, please take the time to read, in depth, the
rest of the information in the enclosed manual. It will give you perspective
on how to attain the greatest possible performance from this most exacting
woofer system.
If you should experience any difficulties in the setup or operation of your
MartinLogan subwoofer, please refer to the Room Acoustics, Placement
or Operation sections of the enclosed owner’s manual. 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. Please retain the original
packing materials for future use—replacement packaging may be expensive.
Step 2: Placement
You may choose to begin by placing the subwoofer in a corner near the
front of the room. If placed in a corner, align the subwoofer diagonally
so both woofers are equidistant from the adjacent wall. Before decid-
ing on a permanent corner placement, experiment with other positions.
Locations away from corners often prove more effective in providing
ideal low-frequency performance and blend with the main speakers.
Please see the Placement section for details.
Step 3: Signal Connection
Use the best cables you can. High quality cables, available from your spe-
cialty dealer, are recommended and will give you superior performance.
Attach your preamplifier/processor outputs to the signal input connec-
tors located on the subwoofer’s rear panel. Please see the Controls and
Connections section for details.
If you plan to connect your subwoofer using Speaker Level (high level)
inputs, refer to the Speaker Level Inputs section for details.
Step 4: Power Connection (AC) (see warning)
Make sure the level knob is set at 0. Plug the subwoofer into a wall out-
let. Review the AC Power Connection section of this manual for details.
Step 5: Setting the Controls
• Set the Level knob to 3 or 4.
• Set the Mode switch to ‘Auto (Trigger)’.
• Set the 25Hz Level knob to 0.
• Set the Phase knob to 90°.
• Set the Low Pass Filter knob to a setting lower than the low-end fre-
quency response of your main speakers. If you are uncertain of your
main speaker low-frequency response, start with a setting of 35Hz.
Step 6: Listen and Enjoy.
