If you are using a pream-
pli fi er which does not have
a sub/LFE output, you can
send its left and right front
output into the sub woof er’s
line-level inputs and then
connect the sub woof er’s
high-pass outputs to the
inputs of your amplifi er.
The subwoofer will play
the low frequencies and
your amplifi er and front
speakers will play the
fre quen cy range above the
subwoofer’s fi xed high-
pass crossover point.
The signals coming out of
the subwoofer’s high-pass
outputs are not affected
by any of the controls.
They are just a copy of the
signals going in except that
the low bass is fi ltered out.
This uses the sub woof er’s
passive crossover network,
rather than the active net-
work and con trols.
This is an excellent
method if your speakers are small satel-
lites or mini-monitors, and/or your power
amplifi er is of limited power, such as a
tube amp.
