MartinLogan 212, 210 user manual Optional Wireless Connection, English

2Connect 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:

1For 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.

2The 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.
