Dolby Pro Logic (Non-Digital)-Line Level
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: 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
amplifier only has one
subwoofer output 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
correctly; Make sure that the
subwoofer 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.
