Simultaneous 2-Channel/Multi-
Channel Mode
The advantage of this dual mode is that you are able to achieve
an optimum setup for stereo listening and still allow for multi-channel
(movie) mode listening. When listening to stereo source mate-
rial the system achieves optimum music integration. In this mode
the subwoofer plays only below the front main speaker's lowest
response frequency. While in movie mode the LFE track and the
bass from the surrounds can be fed to the subwoofer using cross-
over settings from the processor's bass management system.

XLR LFE connections discussed here.
Signal Connection:
1 Connect the left out/right out from your processor to the Left
In/Right In of the subwoofer. Use either RCA or speaker level
connections, but choose only one connection method—do not
use both at the same time for left/right inputs. Use quality RCA
interconnects or speaker cable. Speaker level connections are
discussed in detail later in this manual.
2 Connect the Sub output of the processor to the subwoofer's
LFE In. Use quality RCA or XLR interconnects. Please note, the
connection method for the LFE In does not need to match Left
In/Right In. If you used RCA interconnects or speaker level con-
nections for Left In/Right In it is acceptable to use XLR for the
LFE Input. Be flexible, experiment, and listen to determine what
sounds best in your unique installation. Do not use multiple
methods of connection at the same time for the LFE input (i.e.
connecting both XLR LFE In and Line Level LFE In).
Recommended Control Settings:
IMPORTANT! If you intend to use Anthem Room Correction (ARC)
room correction we recommend running ARC and optimizing
placement of your subwoofer prior to adjusting the subwoofer's
controls. When engaged, ARC will affect the acoustic output of
your subwoofer and influence the settings described below.
1 Set the subwoofer's Control Setting to App.
12
2 Set your processor controls for front speakers to wide, large, or full
mode. If your front speakers are small (e.g. bookshelf type speak-
ers) we recommend that you not use this method for connecting
your subwoofer and instead refer to the "Multi-Channel Mode"
section. Set processor controls for center and effects type speak-
ers to narrow, small, or limited mode. Remember, few center and
effects type speakers are designed to go much lower than 70Hz,
which means that any bass information in a soundtrack lower than
this frequency will be lost. When you set your center and effects
type speakers to narrow, small, or limited mode, all of the bass
lower than the assigned crossover point will be redirected to the
subwoofer along with the LFE output—guaranteeing that no bass
information from these channels is lost.
Please note: Some processors allow the changing of speaker
configuration based on source material type. Under these con-
ditions the user may want to run the fronts in narrow, small, or
limited mode for multi-channel source material and run the fronts
in wide, large, or full mode for 2-channel stereo source material.
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.
3 Calculate the number equal to 70% of your main loudspeaker's
lowest frequency rating. Us the Subwoofer Contrl App to set
the Low Pass Filter to a setting equal to the resulting number. If
the resulting number is lower than 30Hz, set this to 30Hz.
4 Play familiar music with bass content. Use the Subwoofer
Control App to increase the Volume (level) until the music has
deep extended bass. Be careful to avoid levels that become
overwhelming.
5 Using the Subwoofer Control App, try Phase and Polarity
(Inverted) in different settings until the best blending is obtained.
Play familiar music with deep, repetitive bass. Adjust the Phase
and Polarity (Inverted) so the bass notes seem their loudest and
without blur when heard from your typical listening position.
If you are augmenting MartinLogan loudspeakers, we suggest
you start with Phase set at 90° (with Inverted polarity turned on)
when experimenting.
6 With multi-channel source material playing, use the bass man-
agement section of your receiver/processor's speaker setup
