Earthquake Sound P8 System Configurations, Connections to a pre- amplifiers subwoofer output

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.
