System Configurations

The following pages show some typical connections 
that you might make in your installation. They show 
how the inputs and outputs of the Earthquake sub are 
connected to your pre-amplifier or receiver.

Connections to a pre-
amplifier's subwoofer output

If your pre-amplifier has a subwoofer output (often 
labeled LFE for Low Frequency Effects), it can be 
connected to the subwoofer's Left (Mono) input as 
shown. This is the simplest and recommended 
connection. A receiver with a sub/LFE output can be 
connected in the same way.

The subwoofer will play the low frequency range and 
the other speaker will play the frequency range 
delivered to them by your amplifier.

If you have a home theater pre-amplifier, it may have 
an independent subwoofer volume control. Make sure 
this is correctly adjusted, and that the Earthquake 
subwoofer's crossover frequency is set to 100Hz. This 
is by no means an iron-clad rule, rather it is a good 
starting point. 

You can set the subwoofer's Bass Level control on 
your receiver to 0dB, and then use the pre-amplifier's 
subwoofer level control for normal and routine 
adjustments.
