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 volumecontrolled
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
subwoofer. IMPORTANT: Do
not use the LFE input on the
subwoofer with Dolby
Pro Logic processors. NOTE: If your receiver or
amplifier has only 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
output jack, and connect each
of the two female ends to
separate RCA-type
interconnects. Finally, plug the
RCA-type interconnects 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
configured to indicate that the
subwoofer is “On.”
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 “Sub-
woofer On.” Also configure
your receiver for 5.1-, 6.1-
or 7.1-channel operation as
appropriate. 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 100Hz or
the setting that is the closest
frequency below it.
