(1) Volume Control

Manual volume control to regulate your subwoofers power output, to prevent clipping and distortions caused by overpowering.

(2) 50Hz - 160Hz Frequency Adjustment

This controls the high frequency cutoff point. With the control set to the middle, the subwoofer will reproduce frequencies up to 105Hz. If the control is set fully clockwise, the crossover is bypassed and the subwoofer will reproduce a wide frequency range. With the control fully counter-closkcwise the subwoofer reproduces a narrow range, up to 50Hz.

Rotate the control until the bass sound natural. If the mid-bass sounds natural but you want more low bass, turn the control down a little.

The LED will light red when the amplifier is in standby mode and green when the amplifier is on and receiving a signal.

(5) Line Level RCA Inputs

Connect with RCA type patch cords to the line level output of your receiver or pre-amp.

If your pre-amplifier or receiver has a single sub/LFE output, connect it to the subwoofer's left input jack.

There is no need to use the subwoofers right input jack. If you want to run your main/satellite speakers full range, use a "Y" adapter at the pre-amplifier outputs.

In this way, you can send the pre-amplifier's output signal to your main amplifier and to the subwoofer at the same time.

(3) 0-180° Phase Shift

This control is used to acoustically match the subwoofer’s output to your main speakers. Select the position, either 0° or 180°, in which your subwoofer has more output at the listening position.

(4) Power Status LED

Earthquake powered subwoofers have an LED on the panel that indicates the status of the built-in amplifier.

(6) Sub Operation Switch

In LFE position, the Frequency adjustment becomes disabled and the subwoofer runs in a Full range mode, from 20Hz - 2kHz.

While in Sub position the subwoofer reverts to the manual frequency adjustment, allowing the user to operate and fine tune the subwoofer to their personal taste.
