First Time Setup

Step One
Place the Subwoofer in the most optimal position.

Fluance recommends having the woofer face the listener while being positioned near the front channel speakers in a corner if possible.

Step Two
Attach the Subwoofer Cable to the LFE/LOW Level Input on the backside of the Subwoofer.

Step Three
Attach the same Subwoofer Cable to the Subwoofer Output of your home theater receiver.

Step Four (Optional)
Attach Speaker Wire to the speaker inputs of the Subwoofer. Attach same Speaker Wire to the channel outputs of your choice on the home theater receiver. Refer to receiver manual for setup instructions.

Additional Settings

Crossover Settings

The Volume/Crossover settings can be adjusted with the Volume/Crossover knob located on the back panel of the Subwoofer. The Crossover setting changes the cut off frequency for the Subwoofer.

Auto Setting

By selecting the Auto setting, the Subwoofer will automatically turn on when it detects a signal from the home theater receiver. The auto setting turns the Subwoofer on when the frequency signal reaches a required voltage. A 100Hz signal requires 3mV and a 1KHz signal requires 5mV.

Phase Setting

If your speaker system or DB10 is out of phase, it means that the driver/woofer is moving in the opposite direction of the other drivers/woofers. This causes frequencies to be canceled out, which can result in a poor listening experience. By adjusting the phase setting of the DB10, you can ensure the DB10's woofer is moving in the same direction as your other speakers, which will result in a more pleasant listening experience.
