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 interconnects to
connect the line-level sub-
woofer outputs on your receiver
or amplifier to the line-level
inputs on the subwoofer.
Use this installation method for
Dolby Digital, DTS or other
digital surround processors:
Use either the left or right line-
level input jack for the Low-
Frequency Effects channel; it
doesn’t matter which one you
choose.
IMPORTANT: Make sure that
the LFE/Normal toggle switch
is in the “LFE” position. This
will bypass the subwoofer’s
normal low-pass filter,
reducing the possibility of
signal degradation and more
accurately reproducing the
program materials. However, if
your receiver is passing a full-
range signal through its
subwoofer output, place the
toggle switch in the “Normal”
position, which will activate
the low-pass filter and protect
the subwoofer from possible
damage.
Connect this jack to the LFE
output or subwoofer output on
your receiver or amplifier. Con-
nect each speaker to the cor-
responding speaker terminals
on your receiver or amplifier.
Make sure that you have con-
figured your surround sound
processor for “Subwoofer On.”
Also, remember to configure
your receiver for 5.1-, 6.1- or
7.1-channel operation as
appropriate.

®
(OR OTHER DIGITAL SURROUND MODE) CONNECTION
IMPORTANT: Make sure that
the LFE/Normal toggle switch
is in the “Normal” position.
This will activate the sub-
woofer’s low-pass filter, pro-
tecting the subwoofer from
possible damage and enabling
it to operate most efficiently by
reproducing only the low-
frequency materials that it is
best at handling.
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 interconnects. Finally,
plug the RCA-type intercon-
nects into the line-level inputs
on the subwoofer.
Connect each speaker to
the corresponding speaker
terminals on your receiver
or amplifier.
Make sure your receiver or
processor is correctly config-
ured to indicate that the sub-
woofer is “On.”
Note for advanced users: If
your receiver/processor has
a built-in low-pass crossover
filter for the subwoofer output,
you may switch the LFE/ Nor-
mal toggle switch to the “LFE”
position to bypass the sub-
woofer’s internal crossover.
