Audio And AC Power Connections

Note: Make all connections with the
Powered Subwoofer switched off.
The Powered Subwoofer can be
connected to the main amplifier's
speaker outputs, from stereo
preamp outputs or from a mono
subwoofer output.
Using the speaker outputs of
your main amplifier to drive the
Powered Subwoofer is usually the
best way to connect the Powered
Subwoofer, even if you have a
separate preamp or subwoofer
output (like the subwoofer output
on a Dolby Digital ® (AC-3) system).
If you have large Left and Right
speakers and a Dolby Digital (AC-3)
system, please be sure to read the
note at the end of this section.
Connection Method One:
Connect directly to an amplifier or
receiver's speaker output terminals
using conventional speaker wire
(Figure 1 on page 3). You can use
lightweight speaker wire (20-22
gauge) because this is a high im-
pedance connection. The Powered
Subwoofer uses virtually none of
the amplifier or receiver's output
power. Be sure to connect these
new speaker wires to the same
2
speaker outputs used by your main
speakers. Do not use any additional
speaker output terminals your
amplifier or receiver may have.
Alternatively, you may connect
the speaker wires between the
Powered Subwoofer and the input
terminals of your main speakers
instead of the amplifier or receiver's
speaker output terminals.
Be sure the speaker wire connects
the positive (+) terminals of the
subwoofer to the positive (+)
terminals of the amplifier or re-
ceiver (and similarly connects the
negative (–) terminals together). All
two-conductor speaker cable is
coded along one conductor by
lettering, a stripe or a raised bead
-or- the appearance of the two
conductors differs, usually one
copper and one silver. This allows
you to easily connect the proper
conductor to each terminal.
Connection Method Two: Connect
from a stereo preamp output to the
Powered Subwoofer's Line Level
inputs. A suitable length of conven-
tional stereo phono cable with RCA
plugs at each end is all you need if
your preamp has an unused stereo
preamp output.
