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
crossover frequency
between the subwoofer and
the main speakers, select
100Hz or the setting that is the
closest frequency below it.
NOTE: If your receiver or
amplifier only has one sub-
woofer 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 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.
