Optional Wireless Connection - MartinLogan Balancedforce 210 User Manual

2 Connect the Multi Out of the subwoofer to LFE In / Multi In of
the next subwoofer. Use a quality RCA interconnect.
WARNING! Never connect the the subwoofer's
Multi-Out to the input of an amplifier connected to
a full-range speaker. The encoded signal from the
Multi-Out contains high-frequency information that
may potentially damage tweeters.
3 Repeat step 2 for each additional subwoofer in the chain.
Recommended Control Settings:
1 For the first subwoofer in the chain, adjust the control set-
tings using the procedure described for the connection
method used (e.g. 2-Channel Mode, Multi-Channel Mode, or
Simultaneous 2-Channel/Mulit-Channel Mode).
If you are using a custom low-pass filter, load the custom low-
pass only on the first subwoofer. There is no need to load this
filter on additional subs.
If you are using PBK room correction, after connecting all of
the subs, attach the PBK system to the first sub and run PBK as
you would if you were only measuring one subwoofer.
2 The Level, 25Hz Level, Low-Pass Filter, and Phase settings
for additional subwoofer will no longer function. The Tone
Sweep, Room EQ, and Custom Low Pass buttons will also no
longer function. The Mode control on additional subs must be
set to 'Auto (Trigger)' to allow the power status of additional
subwoofers to synchronize with the first subwoofer.
Regardless of how you use your sub, experimentation often
results in better sound. Don't be afraid to try different settings.
You can always return the controls to their previous settings.
