Step Four (Optional) Step Five
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.
Connect the Power Adapter to the
wall outlet. Set the Power Switch to
either ON or AUTO.
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.

7
Auto Setting
Phase 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.
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.

What is the purpose of the speaker wire inputs?
The speaker wire inputs can be used as an alternative to connect your DB10 to your
home theater receiver, however, Fluance recommends using the LFE/Low Level input
connected via subwoofer cable. LFE (Low Frequency Effect) refers to a channel
specically intended for deep, low-pitched sounds ranging from 3-120Hz.
How do I adjust the volume / change the crossover settings?
The volume/crossover settings can be adjusted via the volume/crossover knob located
on the back panel of the DB10. The crossover setting changes the cut off frequency for
the subwoofer.
What is the auto setting and what are the parameters?
By selecting the auto setting the DB10 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.
What is the phase setting and what is the optimal 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.
What does the LED behavior mean?
Green LED = Power On
Red LED = Protection Mode
What is Protection Mode?
Amplier Protection Mode is a shutdown state that ampliers can enable to prevent
serious damage to the unit or other components in the system. Protection Mode can be
activated in two scenarios:
1. Unit is overheated – Ensure the area surrounding the DB10 is at room temperature,
power off and unplug the power adapter.
2. The unit is not installed properly – consult the included quick start guide and
manual, ensure no wires are touching.
