2) If your receiver/amplifier
has subwoofer outputs 
or preamp output jacks
for the left, center and
right channels, or left
and right only.
If your receiver/amplifier
has a single (mono) sub-
woofer output or LFE out-
put, you may connect the
output to either the Left,
Right or Center line-level
input on the subwoofer.
However, to maximize the
subwoofer’s performance, we
recommend that you use a
“Y”-connector (not includ-
ed). Plug the single male
end of the “Y”-connector
into the subwoofer output
on the receiver/amplifier,
and connect each of the 
2 female connectors to an
RCA-type interconnect
cable. Then connect the 2
interconnect cables to the
Left and Right line-level
inputs on the PSW-D115.

3) If your receiver/processor
contains Dolby* Digital or
DTS® surround processing
technology, then connect
the subwoofer or LFE out-
put from your receiver/
processor to the Center
line-level input as shown.
Set the “Low-Pass” control
to the 180Hz position.
When hooked up using this
method, all of the crossover
and level adjustments are con-
trolled through the receiver/
processor.
