Multi-Channel Mode - MartinLogan Dynamo 800X User Manual

Multi-Channel Mode

This setup is recommended if you will use your subwoofer in a
dedicated home theater or other multi-channel system. When a
signal is connected to the subwoofer's LFE In, the setting for the
Low-Pass Filter control is not used. Your processor handles most of
the bass management.
• D 600X and 800X: These subwoofers do not offer the
ynamo
XLR LFE connections discussed here.
• D 600X: If connecting a D
ynamo
od, please note that the Right In doubles as the LFE In and you
should set the subwoofer's Low Pass Filter to Bypass using the
Subwofoer Control App.
• SWT-X Wireless System used with any subwoofer: If connect-
ing the sub using a SWT-X wireless system, please note that the
SWT-X receiver's Right In doubles as the LFE In and you should
set the sub's Low Pass Filter to Bypass using the Subwoofer
Control App.
Signal Connection:
1 Connect the Sub output of the processor to the subwoofer's LFE
In. Use either an RCA or an XLR interconnect—do not use both
at the same time.
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.
2 If your front speakers are large (e.g. full-range floorstanding
type speakers) set your processor controls for front speakers to
wide, large, or full mode. If your front speakers are small (e.g.
bookshelf type speakers) set your processor control for front
speakers to narrow, small, or limited mode. Set processor con-
trols for center and effects type speakers 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 normally 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
10
600X using this meth-
ynamo
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
receivers/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 pro-
cessor attempts to drive the speaker beyond its
rated frequency range. This warning also applies
to products from other manufacturers.
3 With multi-channel source material playing, use the Subwoofer
Control App to adjust the Volume (level) control to your preferred
level. Be careful to avoid levels that become overwhelming.
4 D 600X and SWT-X Wireless System used with any
ynamo
subwoofer: Use the Subwoofer Control App to set the Low
Pass Filter to Bypass.
D 800X, 1100X, and 1600X: When using a cable to
ynamo
connect your receiver/processor to the LFE Input changing the
Low Pass Filter will have no effect on the sub's output. Their LFE
input internally bypasses the sub's Low Pass Filter.
5 Use the Subwoofer Control App and try the 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 0° (although we suggest 90° elsewhere, in this
specific connection method we suggest 0° since your processor
will be doing most of the bass management).
6 If you have completed steps 1–5 and still have weak or boom-
ing bass consider using the Subwoofer Control App to adjust
20–30Hz Level to compensate for these anomalies. Experiment
with the settings and listen to the result. Try to find a position
that sounds correct to you. Experiment by changing the Volume
(level) setting while adjusting the 20–30Hz Level. Find a posi-
tion that gives you deep extended bass and good blending
with your main speakers.
