Use this installation method with
an analog receiver/
processor that does not have
digital processing or bass
management, and is equipped
with a full-range subwoofer out-
put or a volume-controlled pre-
amp (line-) level output:

Use RCA-type patch cords 
to connect the line-level sub-
woofer outputs on your receiver
or amplifier to the line-level
inputs on the subwoofer. 

IMPORTANT: Make sure that the
LFE toggle switch on the
subwoofer is in the “Normal”

position. Do not use the “LFE”
position with Dolby Pro Logic-
only processors. 

Note: If your receiver or ampli-
fier has only one subwoofer out-
put jack, then you may connect
the subwoofer output on your
receiver/preamplifier to either
the left or right line-level input
on the subwoofer. It makes no
difference which jack you
choose.

Connect each speaker to the
corresponding speaker
terminals on your receiver or
amplifier.

Make sure your receiver or
processor is configured cor-
rectly: Make sure that the sub-
woofer is configured as “On.”

Note for advanced users: If your
receiver/processor has 
a built-in low-pass crossover
filter for the subwoofer output,
then the LFE switch should be
set to the “LFE” position to
bypass the subwoofer’s internal
crossover.

For LFE use L or R
