User's Manual

If you are using a receiver or
processor which does not have
a Sub/LFE output, you can send
its left and right front output
into the subwoofer’s Line-Level
inputs and then connect the
subwoofer’s High-Pass outputs
to the inputs of your amplifier.
The subwoofer will play the
low frequencies, and your
amplifier and front speakers
will play the frequency range
above the subwoofer’s fixed
(70 Hz) high-pass crossover
point.
The signals com-
ing out of the sub-
woofer’s high-pass
outputs are not
affected by any of
the controls. They
are just a copy of
the signals going
into the subwoofer
except that the
low bass is filtered
out. This uses
the subwoofer’s
passive crossover
network, set at 70
Hz, rather than the
active network and other controls.
This is an excellent method if your
speakers are small satellites or mini-
monitors, and/or your power amplifier is
of limited power, such as a tube amp.
For the ultimate in computer sound
systems, connect the left and right audio
output from your computer sound card
into the subwoofer inputs. Connect the
sub's high-pass outputs to the inputs of
your powered speakers. You may need
some RCA-to-mini plug adaptors to make
the connections. Adjust the sub's volume
control to match low-powered speakers.
See the note about magnetic fields on
page 10.
