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-connec-
tor into your receiver or ampli-
fier’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 config-
ured 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 con-
figured 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.
