Placement
Note: Always provide adequate space for
ventilation
of the Subwoofer amplifier. Do not
place the Subwoofer directly against a wall,
curtainsoranyothersurface.
For best results, try to place the subwoofer
in the
same horizontal planeand along the
-same wall as
thefront satellite speakers (Positions
A, BorC).
Connections
Make sure all components are powered off and
that the Subwoofer
is not plugged in to the AC
outlet until all connections are completed.
1 Connecting Your Subwoofer to Your AV
Surround Receiver
The most common connection for receivers is to
run a single audio cable from the receiver
Subwoofer or LFE output to the LFE input. The
LFE input bypasses the Subwoofer's crossover
control. Follow the instructions in your receiver's
speakersetup menu to enable the subwooferand
makecrossoversettings.
2 Connecting Your Subwoofer Using Your
Receiver's Preamp Out
Some older surround receivers/processors only
offered preamp outputs. Connect a pair
of audio
cables from the Left and Right Preamp output to
thetwo Line In jacks on the Subwoofer. Followthe
instructions
in Control Settings below for setting
the Subwoofer'scrossoverpoint.
Some newer stereo receivers have pre-amp
outputs and in some cases they also have a
subwooferoutput. Ifconnecting from the preamp
out
on your receiver follow the instructions
immediately above. If connecting from a
subwooferout, use a single RCAcable to the Line
in (either left or right). Follow the instructions in
Control Settings below for setting the
Subwoofer'scrossoverpoint.
