Use this installation method for
Dolby Pro Logic applications
(not Dolby Digital, DTS

®

or

other digital processing), where
the receiver/processor is
equipped with a subwoofer
output, or a volume-controlled

preamp (line-) level output:
Use RCA-type patch cords 
to connect the line-level
subwoofer outputs on your
receiver or amplifier to the line-
level inputs on the subwoofer. 

IMPORTANT: Do not use the
LFE input on the subwoofer
with Dolby Pro Logic
processors. 
Note: If your receiver or
amplifier only has one sub-
woofer output jack, then you
will need to use a Y-connector
(not included). Plug the male
end of the Y-connector into
your receiver or amplifier’s
subwoofer output jack, and
connect each of the two female
ends to separate RCA-type
patch cords. Finally, plug the
RCA-type patch cords into the
line-level inputs on the
subwoofer.
Connect each speaker to the
corresponding speaker
terminals on your receiver or
amplifier.

Connect this jack to the LFE
output or subwoofer output 
on your receiver or amplifier.
Connect each speaker to the
corresponding speaker
terminals on your receiver or
amplifier.
Make sure that you have
configured your surround-
sound processor for
“Subwoofer On.” The front left,
front right, center and rear
speakers should all be set to
“Small.”

Note:
When using the LFE input, the
subwoofer's Crossover control
is NOT active, because this
function is controlled by your
surround processor.
When using the LFE input, set
the subwoofer's Volume control
to "Max" and calibrate the
subwoofer level along with the
other speakers according to
the set-up instructions in the
owner's manual for your
surround receiver/amplifier.

Use this installation method for
Dolby Digital, DTS

®

or other

digital surround processors: 
Use the line-level input jack
marked “LFE” for the Low-
Frequency Effects channel.
