DOLBY PRO LOGIC (NON-DIGITAL) – LINE LEVEL
Use this installation method
for Dolby Pro Logic appli-
cations (not Dolby Digital,
DTS or other digital process-
ing), 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 sub-
woofer outputs on your
receiver or amplifier to the
line-level inputs on the sub-
woofer. IMPORTANT: Do not
use the LFE input on the sub-
woofer with Dolby Pro Logic
processors. NOTE: If your
receiver or amplifier only has
one subwoofer 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 out-
put 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 sub-
woofer.
Connect each speaker to
the corresponding speaker
terminals on your receiver
or amplifier.
Make sure your receiver or
processor is correctly con-
figured to indicate that the
subwoofer is “On.”
Note for advanced users: If
your receiver/processor has
a built-in low-pass crossover
filter for the subwoofer out-
put, you may use the LFE
input to bypass the sub-
woofer’s internal crossover.
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.
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
receiver should be config-
ured for 6.1-channel opera-
tion (if available), and the
front left, front right, center
and rear speakers should all
be set to “Small.” If your
receiver allows you to set
the crossover frequency
between the subwoofer and
the main speakers, select
120Hz or the setting that is the
closest frequency below it.
