Dolby Pro Logic (Non-Digital) – Line Level
Use this installation method
for Dolby Pro Logic appli-
cations (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

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.

Make sure your receiver or

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.
