MartinLogan Dynamo™ 1500X 사용자 매뉴얼

Connections and Control Settings     23

MartinLogan's engineering and design team developed 
the Dynamo 1500X subwoofer for easy setup and system 
integration. Before beginning to connect your subwoofer, 
please review the controls discussed in the last section. An 
understanding of these will help speed you along as you 
connect and integrate your subwoofer with your system. 
All signal connections are done on the rear connections 
panel of the subwoofer. Make certain that all of your con-
nections are tight.

WARNING! Unplug your subwoofer before 
making or breaking any signal connections!

This setup is recommended if your subwoofer will be used in 
a 2-channel system with main speakers playing full range.

If you will be using your system for both 2-channel and 
multi-channel listening we recommend connecting the 
subwoofer as recommended in 'Multi-Channel/LFE Mode' 
on the next page. Some modern receivers and processors 
allow users to route left and right channel low-frequen-
cy information, in addition to discrete LFE information, 
through the LFE output.

1  Connect the left and right outputs of your preamplifier 

to the left and right inputs using quality RCA intercon-
nects. If your preamplifier only has one set of outputs 
you may need to obtain Y adapters from your dealer.

1  Set the 'Low Pass Filter' knob to approximately 70% of 

your loudspeakers lowest frequency response.

2  While playing music with bass content, turn the level 

control up until the music has deep extended bass, 
being careful to avoid levels that become overwhelming.

3  Try the phase control in different settings until the 

best blending is obtained. If you are augmenting 
MartinLogan loudspeakers, we suggest you start with 

the phase set at 90°.
