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 interconnects
to connect the line-level
subwoofer 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 intercon-
nects. Finally, plug the RCA-
type interconnects 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 5.1-channel
operation, and the front left,
front right, center and rear
speakers should all be set to
“Small.” If your receiver
allows you to set the cross-
over frequency between the
subwoofer and the main
speakers, select either 120Hz
or 150Hz, or select the set-
ting that is the closest fre-
quency below these.
