Connection and Setup (continued)
IMPORTANT NOTE: One terminal on each channel
input is marked with a red band (+) and the other
is marked with a black band (–). Make certain that
you connect the wire from the red (+) terminal of
your amplifier or receiver to the red (+) terminal
of the subwoofer and the wire from the black (–)
terminal of your amplifier or receiver to the black (–)
terminal of the subwoofer. It is essential to connect
all speakers in the system to the amplifier in the
same way (to the correct polarity.) If you experience
poor bass, one or more of the channels may be
connected to the incorrect polarity and may need to
be rewired. Pay close attention and connect positive
to positive and negative to negative on all channels.
3. Connect the subwoofer to an AC power source
and turn it on (see page 10).
4. Start with the default volume and adjust as needed.
5. If the system is 2-channel, skip to step 9 below.
6. If the receiver is a multi-channel device, turn on
the receiver's power and access the "speaker setup"
or "speaker configuration" menu.
7. Set the subwoofer to "None" or "Off".
8. Set front left and right speakers to "Large".
9. Proceed to page 13 for subwoofer adjustment
and system tweaking.
