DIGITAL RECEIVER/PROCESSOR – 
LFE CONNECTION
Use this installation method for
Dolby Digital, DTS
®
or other digi-
tal surround processors that
have bass-management
programming, or for analog
receivers/processors that have
a filtered subwoofer output: 
IMPORTANT: Make sure that the
LFE toggle switch on the sub-
woofer is in the “LFE” position.
Use the line-level input jacks for
the Low-Frequency Effects
channel.  Connect these jacks to
the LFE output or subwoofer
output on your receiver or
amplifier. 
Note: If your receiver or ampli-
fier has only one subwoofer out-
put jack, then you may connect
the subwoofer output on your
receiver/preamplifier to either
the left or right line-level input
on the subwoofer. It makes no
difference which jack you
choose. 
Connect each speaker to the
corresponding speaker termi-
nals on your receiver or ampli-
fier.
Make sure that you have config-
ured your surround-sound
processor for “Subwoofer On”
or “LFE On.” The front left, front
right, center and rear speakers
should be set to “Small” or
“Large” depending on their size
and frequency response.
Consult your receiver’s or
processor’s owner’s manual.
