Phase Setting
If your speaker system or DB12 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 can-
celed out, which can result in a poor listening experience. By adjusting the phase setting
of the DB12, you can ensure the DB12’s woofer is moving in the same direction as your
other speakers, which will result in a more pleasant listening experience.

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.

What is the purpose of the speaker wire inputs and outputs?
The speaker wire inputs can be used as an alternative to connect your DB12 to your
home theater receiver, however, Fluance recommends using the Low Level input
connected via subwoofer cable.
Note: To connect passive speakers to the speaker outputs on the DB12 ensure the amplier/
home theater receiver is connected to the DB12 via speaker wire (not subwoofer cable).
What is the purpose of the Low Level outputs?
The Low Level outputs can be used to connect an additional powered subwoofer to
your home theatre setup. Most receivers only have one subwoofer output so this
feature allows the connection of an additional subwoofer.
How do I adjust the volume settings of the DB12?
The DB12 features a Volume knob on the back of the subwoofer that can increase/
decrease the amplication of the subwoofer output.
What does the LED behavior mean?
Green LED = Power On
Red LED = Protection Mode
What is Protection Mode?
Amplier Protection Mode is a shutdown state that ampliers 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 DB12 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 man-
ual, ensure no wires are touching
