Placing Speakers
All stereo-encoded information is heard through the primary speaker
system. The subwoofer contains no stereo imaging, and its sound is
non-directional. As a result, the subwoofer doesn't have to be placed
in any particular relationship to the speaker system. However, placing
the subwoofer on the floor close to a wall or room corner provides
better bass efficiency and optimum sound.
Warning: The subwoofer is not magnetically shielded. As such, it
SHOULD be placed at least 2 feet (0.6m) from TVs, computer monitors,
computer hard drives or any other magnetic media (e.g., floppy disks,
Zip disks, computer or audio tapes, etc.).

Making Connections
Warning: Do not insert the subwoofer's power plug into a wall outlet
until all connections are made. Also, turn off the primary speaker
system and audio source (i.e., your PC, MP3 player, Sony PlayStation,
etc.) before connecting the subwoofer.
To ensure first-time operation as expected, please carefully follow the
connection sequences described below in the order indicated.
• Locate the 3.5mm stereo cable that came with the BB2001
subwoofer.
• Plug one end of the 3.5mm stereo cable into the output labeled
"SUB OUT' on the back of the primary speaker system.
• Plug the other end of the 3.5mm stereo cable into the input
labeled "SUB IN" on the back of the BB2001 Powered Subwoofer.
Powering On
1. After all other connections are made, plug the AC power cord
(on the back of subwoofer) into a wall outlet. The speaker system
is now ready to operate.
2. Turn on the audio source.
3. Turn on the primary speaker system.
4. Turn on the BB2001 Powered Subwoofer by rotating the
POWER/VOLUME knob clockwise.
Note: To avoid hearing a popping sound when you turn on the primary
speaker system, always turn on your audio source first.
Volume
The POWER/VOLUME knob on the back of the BB2001 Powered
Subwoofer controls the subwoofer volume. Turn the knob clockwise to
increase the subwoofer volume and counterclockwise to decrease the
subwoofer volume.
Phase
The PHASE switch on the back of the unit can improve the acoustic
performance of the BB2001 Powered Subwoofer by allowing you to
put the subwoofer in phase with your primary speaker system.
Depending on its placement, it is possible that the output of the
subwoofer is out of phase with the primary speaker system. This will
result in an overall decreased bass response. To set the switch, compare
listening to the BB2001 Powered Subwoofer together with your
primary speaker system with the switch in, then out, then simply leave
the switch in the position that sounds best.
